He dynoed @ the wheels & made 700 HP @ 6500 RPM w/only 7 PSI of boost pressure..

His engine is designed to go to 9000 RPM.

Normally aspirated (no turbo) car made 411 HP @ 6500 @ the wheels..

Very impressive!!! Douglas.Sorry Douglas,,,I had to give some updates before you,,,but I could not wait.

I tried asking you when I IM you,,but I think you fell asleep.



MBHD

wow! how many psi does he think he will need? 7 psi really woke it up. 14 may break it. hope not. when is douglas going to run it down the 1/4?

sure wish we had more specs on his motor.
cam- lift /duration /type
compression
fuel type.

tom

700 HP at 6500 with 7PSI, is serious! What is it, a good NA engine at sea level is 85% efficient? If I could make my 292 work here like a 100% sea level engine I'd feel great! A few psi is all you need, but a few more..........

Specs on cam are big,solid roller,,Approx 255-260 degress duration @ .050
.700 lift,115 lobe center or there abouts IIRC?

He is planning on running 30-35 psi.
8.5 to 1 compression.

Fuel type is methanol.

The engine is a 250 L6 w/a Kirby/Sissell 12 port head.

The engine is not built to run normally aspirated,he just did the normally aspirated runs to do baseline tunning & make sure there are no other problems before he put the turbo on.

He hopes to make 1100-1400 HP to the wheels.

He ran it in the 1/4 mile but had problems w/the converter not stalling high enough.

I am pretty sure when he has time to post some more news & pics here ,he will,,,he better!


MBHD

A bit more boost should fix that.

Best of luck to him with it, truly amazing what they are getting out of them at that lattitude.

Some video links.

Correction on the compression ,,it has 10.7:1

MBHD

His car ran 15.2 @ 130 MPH with the boost still only @ 7 psi.

Once he gets the turbo to spool up & make boost on the initial launch,,,,whatch out!!

He might break the record now in Brazil of 8.4 seconds w/just the 700 HP.

The guy that set the record,,his car makes 1000 HP.

Should be interesting to see it run good.


MBHD

from the vids, it looks as though he has abit more tuning to do. no surprise to me. once he gets the tune ironed out then he will have the cat by the tail. tom

I gave a few tips on hopefully to get the turbo to spool up tunning wise.

We will hopefully see it set all new records.

He really put in a lot of time,effort & not to mention money into his really nice looking car.

MBHD

Another pre update.
Tomorrow 7-12-09,,, Douglas told me he is going to the race track.

He said he will be running 20-22 psi of boost pressure.
He estimates it will me making over 1000 HP.

Hope all goes well!

GO DOUGLAS!


MBHD

Yes, good luck to Douglas.

OK,
here's the update,he ran two passes with the nitrous (only used to spool up turbo,meaning launch only)

1st,10.15

2nd 9.0 @ 155 MPH 243 KPM,,no time requested

http://www.youtube.com/watch?v=95Jk6jw345k

1.3 60 ft time.

Launched @ only 4800 rpm & 7 psi of boost pressure ran 14 psi up until it reached 7000 rpm in 2nd & he saw 26 PSi,so he let off.

He said he needs to look into why it did that.
But he said it is scary fast & during the passes he only saw 35-45% TPS,he is getting used to the car still.

He was the limiting factor as why it was only seeing 35-45% ,,, his foot. LOL.

It has a lot more potential.

Way to go Douglas,!!!

Keep it up!!!


MBHD

Thanks guys!!

We finally ran the car launching like we want!
The car runs straight as an arrow... I´m really happy!

I´m just a little scared about how the car keep pushing on all rpm ranges. It seems that the engine have NO END!!!

We are not revving what the cam needs yet, but we are upgrading the power level as I´m getting used with the car...
It´s like I´m racing for the first time!!!

Next step, we´ll see what was the problem with that 26PSI boost at 2nd gear, and we´ll try to get more boost on the launching.
The goal is a 1.1 60ft time...

Here is some more videos of the testing day:

First Burnout: http://www.youtube.com/watch?v=nC2ZKgJJcb8&feature=channel_page

First 10.15s pass: http://www.youtube.com/watch?v=ek7wCI9wEJo&feature=channel

Second Burnout: http://www.youtube.com/watch?v=uqfscY9192c&feature=channel

Talk to you later, guys...
Hope you like it!!

Douglas Carbonera - Brazil

Douglas,

Your car sounds great! Keep up the good work.

That is good to here! That is when all the long nights in the work shop pay off. Now you give me a ET goal to shoot for LOL.

[quote=MIGHTY6]

Ahh, a challenge ;-) .

Douglas is shooting for 7's

7s

Yes, good luck indeed, that's a lofty goal for anyone with a full bodied car.

Well,,, it is a complete tube chassis car ,that weighs approx 2400 LBS,maybe less.
His orange Opala weighs 2000 LBS

He is looking to make 1400 + HP.


MBHD

It is all in good fun!

I think a honest goal for us is 8.80-8.90 @ 3000 lbs. That is with a 10.5 wide tire and stock style suspension.

Steven

Yes, but it's still not a rail car, so there's going to be some aditional difficulty there.

Not insurmountable, just a bit more of an accomplishment when it's achieved.

Hank,
Any news on Douglas's car at the higher boost.

Harry

Hi Harry,

his next race is August 8th.

Not sure if he has done anything else to his car.

I believe he will turn the boost up more,he says driving his race car is just like learning to drive a car all over again.

Very intimidating/scary ;-)

He has a new Y2K Turbonetics BB turbo he will eventually use, but for now he is going to play around/tunning with the 94 MM non BB turbo.

Other than that,I think he is just waiting for the next race.

MBHD

Update,Douglas 1st run today 8.8 2nd run 8.6.

Numbers Taken from a local forum in Brazil.

The record holding Black Opala wagon ( which is 8.4 seconds),seemed to be on an 8.0 pass,but blew up the rear end.
BTW he was running a lot of boost,but now also running Nitromethane.
This info taken from a friend in Brazil.

MBHD

Update, the class record was broken w/Black Opala wagon,record is 7.8 seconds now.
No nitromethane was used,(3rd or 4th hand info) ,but he was running as much as 45 psi!!!

Douglas running 25 psi in 2nd gear & only 14 psi in 1st.

Douglas, still can only launch on 10 psi of boost pressure.

Trans brake problems.

Ran a 1.31 60 ft.

This time out ,,no nitrous to spool up turbo.

Switching to smaller BB Turbonetics turbo next time out.
This pass 9.?? ran lean

Still not dialed in yet,but it's pretty damm fast so far.

http://www.youtube.com/watch?v=jBMHJ-O4l...player_embedded


MBHD

Thats making a little progress!




Soon as he gets issues worked out I think it should go 7.9-8.0 pretty easy



BTW- Why no nitrous to spool the turbo?

Steven

[quote=MIGHTY6] [quote]

Agreed.

Soon as he gets issues worked out I think it should go 7.9-8.0 pretty easy

Yes,transbrake,acting wierd also, w/trans brake, he could only launch @ 7 psi,w/out tranbrake he could get 10 PSI.

BTW- Why no nitrous to spool the turbo?

He decided just to spool it up w/no nitrous,it took several seconds in doing so though.

Going from memory,,The specs on his turbo were 99 MM inducer,104 MM exducer,,w/a 1.45 A/R T6 turbine housing,,,,that's too big,and part of the reason he could only get up to 14 psi in first gear.

S[b]The Turbonetics Y2K turbo has a .96 turbine housing,,,that should help out a lot along w/it being a BB turbo.

His plans (as stated earlier) on running a 1.1 60 ft time & of course setting the record & run 7's.

GO DOUGLAS!!!
MBHD

Here is Douglas' 8.8 second pass

Launching @ a mesily (SP) 7 psi


http://www.youtube.com/watch?v=wYsHgExjA...player_embedded


MBHD

That car really gets the power to ground quick. It just squats on the rears and goes. No chassis flex(or minimal) and no front end lift.

Those of us who have trouble keeping our street cars on the road are fortunate to have guys like Douglas carrying our Inline Banner into battle! Thanks to everyone who is pushing an inline to the extreme. Old Red Chevy pickups at Bonnivelle , little blue pickups that saw off V8 Mustangs and lots more. It gives us all hope and bragging rights at the local watering hole! Tom

Hank this has got me wondering



is this a typo "nitromethane" or "nitrous"

VP Raceing Fuels M5 has a little nitro in it?

Any idea how much hp Doug car make with 25 psi boost?

The cars run on methanol ,,,ALKY

The same source I got my info from,,told me the Black wagon was using nitromethane,,,but later I found out this was bogus info,,sorry bout that.

Douglas has not dynoed his car w/25 psi,,,, but when he raced the record seting Black wagon,,,Douglas was 10-15 KM lower trap speed.IIRC?

I was told that the Black wagon dynoed at 1300 HP,,,,but he is running 45 psi!!! Yow!!

Also,,,the Black wagon boost launches @ 30 PSI also,,where as Douglas launched @ 7 PSI,but still got a 1.31 60 ft.

Douglas, needs to fab up some parts for the Turbonetics Y2K turbo before he installs it.


MBHD

Any pictures of this setup floating around on the internet?

Any pictures of this setup floating around on the internet? [/quote]

I will ask if Douglas can post a link here.


MBHD

Thanks guys!!

We are making some upgrades on my car to make teh car launch harder, and we´ll make some dyno session to get more power from the engine.

I´m really happy with the goals... we are the third 6cyl car in Brazil to run on the 8s, and we did it in the second race of the car!!! That´s great!!!!

So.... here is some pictures of the black wagon engine.
This guy is racing that car since 2003.
Pretty simple setup, but this car have a LOT os power!!!
The turbo is a Bullseye S480 (80mm), 1.22 A/R.



Steven...
Nice work on the Mighty6!!! Hope to hear good news about the engine pretty soon!!

Thanks Doug



Is it me or does that turbo look big for a 80mm. Maybe I am used to seeing my dinky 78mm

Any body notice there are no front brake rotors or radiator.
What does that car weight because looks very simple and well thought out.

Those turbos are T6 size,they are huge!!!


MBHD

That would explain it!

Look at how much wheel stagger is in the front end

Thats explain why the car run shaking side to side all the track!! It´s scary how it´s unstable!!

http://www.dragtimes.com/horsepower-et-t...epower+Estimate

Just a guestimate ;-)


MBHD

Last I talked w/Douglas,he had installed the Y2K turbo on & tried a few boost launches & then the turbo let go.

It had gone to 20 PSi while on the transbrake as compared to 7 psi before w/other turbo.

Wiped out the BB turbo.

I contacted Turbonetics to see if they could help him out w/the repair or replacement of his turbo,(only had 30 day warranty)
But I had no response from them.

I tried.
MBHD

Don't Turbonetics turbo's have a 1 year warranty? That bite's. Tom

Douglas' turbo:
Warranty Exclusions:
Mid-frame, Y2k and Thumper series turbochargers are intended for extreme duty/race applications and are warranted against defects in material and or workmanship only for a period of 30 days from the date of original invoice.

Was this a brand new turbo?

No idea what could have happen to it?

Steven

This was a new $3000 turbo.

I believe the center section let go,bearings went ,compressor wheel rubbed on compressor housing & possibly the turbine wheel hit also?

MBHD

I don't think Y2K turbos have ported shrouds and it went into surge. This usually breaks a turbo faster than anything.

Harry

He stated before when just running the turbo & breaking it in nicely,the compressor wheel rubbed on the compressor housing,he removed the compressor housing ,slightly opened up the clearance of the compressor wheel where it rubbed.
Lightly sanded/polished the compressor housing.

So might have had a problem from the get go?

I am thinking it was assembled incorrectly. Who knows?


MBHD

So now what is he going to do?

Well, for now he only has the Bulleye turbo, but the A/R is too big. 1.45 T6 huge turbo!

Plus the large amout of overlap w/his cam ,, it does not help with spooling that turbo.

I am pushing Turbonetics to consider some type of deal to help him out.


MBHD

How long before he could have a replacement best case?

If Turbonetics are willing to help out w/Douglas,he could have a turbo in 2 weeks or there abouts.

But Douglas does not have an extra $3000 for another turbo @ the moment.

Does not seem they are willing to help out as of yet,as for now it seems they are sticking to there 30 day warranty deal, even though Douglas had installed it, used it & blew up up in about just 2 weeks.

But Douglas had this turbo lying around his house for a couple months or so,not being used.

I am waiting for them to return my email I sent them,cross your fingers for Douglas.


MBHD

A big turbo on a small engine needs a ported shroud since the turbo flows more air than the engine can use at first. The air then backs up in the intake and tries to turn the compressor wheel backwards, with the turbine spinning in the correct direction the two fight each other and ruin the bearings and scrape the housings. The ported shroud allows the air to recirculate to the intake of the compressor until the engine needs the extra air.

A ball bearing turbo does not ride on the oil wedge as a bushing does, therefore needs to be tighter . Also normally needs less oil flow or will pass oil to the turbine and exhaust. Always feel the play by pushing the wheels to the side of the housing for any rubbing action but don't try to make them hit, every time the turbo is off the engine.

Harry

On rally cars they do not use blow off valves because they do not want to loose any throttle responce.

They run a lot of boost & the compressor is surging during on & off throttle position constantly.
The pressurized air has to go somewhere when the throttle is closed,well it does go somewhere, it goes backwards through the turbochager like my Syclone did before I installed a BOV.

I think Douglas' turbo is a 80 MM compressor wheel, is that considered big?


MBHD

Rally cars use small turbos with a wide surge line for on off acceleration. If they were in constant surge they would not last long.
An 80mm turbo is huge if designed right will make 1400 HP. On a inline six it must have a ported compressor housing, the engines are not that big. The advent of the ported housing is what has allowed big compressors on small engines.
Also the ball bearing turbos do not have as good of oscillation support and will rub easier than a normal bushing style, their strong suit is quick spool up.
Everything is a trade off in motor sports.

Harry

My bad Harry, Douglas' Y2K has an 88 mm inducer,= big.

He took apart the Y2K & the shaft is toast.

His Bullseye turbo has the compressor housing anti surge feature.

He said the Y2K made 15 more psi over his Bullseye turbo during testing of the transbrake.

MBHD

MBHD, Do the Bullseye and Y2K have the same turbine size, and compressor size ?

Harry

The Bullseye compressor wheel is 90 MM inducer 100 MM exducer.

Where as the Turbonetics compressor is 88 MM inducer 90 MM exducer according to Douglas. Need to double check that.

I need to ask about the turbine trim & size.
I am pretty sure the turbine wheels are different from eachother.

The Bullseye turbo is a T6 size turbo, it pretty big in size.

MBHD

Here is Douglas on Speed channel in Brazil.
Pretty cool.

http://www.youtube.com/watch?v=R825adfxyq8&feature=player_embedded

He also got the orange car running,4" std bore & will soon be fuel injected on methanol w/14.6:1 compression.
video here is running on 3 45MM Webers

MBHD

Way to go Douglas! Lets see some runs with the red SS. What are the specs for the cam in it? Tom

Great links Hank

That sure is one sweet ride

Thanks for keeping us up on this Hank. That is great coverage for Douglas, and some nice views of the car.

Another update guys.
Taken from his email.
Quote: " Well.... we went to dino to see how the car goes with the new camshaft and no watercooler, and the car shows an impressive power. With only 12 psi, the car made 609 rwhp at 7.300 rpm.
We could not see any number on the dino with REAL PRESSURE, because with 36,4 psi at 8.000 rpm, the car smoke the tires even using VHT on the dino.... That was SCARY!!!!!
On the 2nd pass with 36,4 psi, the car smoked the tires again and the transmission or converter broke.... I will check what happened tonight!! The car is running pure methanol!

On transbreak tests, the car spooled up pretty quick using a lot of timing and lean lambda. 7s to go form idle to 5.400 with 12PSI of boost.

I´m sending the Print of my Fuel Injection datalogger when the car reached 36,4psi of boost on dino. Please note the Back pressure: 34,3psi!!! That was with a Bullseyepower Turbocharger 88mm inducer, 100mm exducer and 1.45 A/R.
We´ll have to choose another dinamometer to read some numbers and tie down the car properly to do not smoke the tires anymore."

MBHD

Another Douglas update but sad

Douglas has blown up the engine.
Basically wiped out everything in the engine,#1 rod broke.
Here was the pass when it broke:
http://www.youtube.com/watch?v=pYb16FFszw0
It ran an 8.5 @ 153 MPH, it would have run an 8.0 if it had stayed together.


More sad news, now Douglas has sold this car, so now he will still be racing,just his normally aspirated car
I believe here are the numbers below:

LUIZCARNIELSIX | May 30, 2010
OPALA Douglas Carbonera 00,239 / 1,339 / 3,716 / 05,545 / 07,062 / 08,586 - 2...


MBHD

Bummer.

blowen up is kinda a understatement.The motor looks more like it was hit with a shredder.But i do feel sorry for him after all that hard work time & money that went into it all.
