45 PSI, that is alot of backed up exhaust. I see why you are going to the bigger housing. I'd love to see your dyno sheet.

What rpm range is the pull and I noticed from the video, the rpm's rise very fast. How many RPM per second is the dyno set for?

Are you going to be able to hold it down at the track? It will be fun. Tom


The pull was 4000 to 6500 rpms. I dont know about the rpms per seconds.

We have a boost controller that is programable. We can ramp in the power as needed.

Douglas has the first EFI turbo setup.

I know that Douglas was fisrt ,forgot to say in the U.S.

Those are some good numbers. Congrats!

Yes, for a drag vehicle & your engine size a .96 is too small.

What is the trim on your turbine wheel?

Have you driven it on the street?
What is the stall on your converter?

What are the exact specs on your turbo? Just curious,I know I will not be as big of a turbo,smaller engine.

We have the first motor with 7 head studs per cylinder

No we have not driven it on the street.

We have 4 convertors I think this one is a 9" 3800 rpm stall

All I can tell you about the turbo is Turbonetics 78mm BB .96 A/R S-trim.

The turbo was Craig's deptment to take care of. I took care of all the wiring. This much wiring would scare most poeple.

You have the correct "S" trim,or did Tlowe give you advise also?
J.K.

It will be nice to be able to cruise it around on the street w/the lower stall converter.
And contrary to popular belief ,,,you could run that 3800 stall converter on the street & not over heat it.

Yes the 7 studs per cyl is a first for that head,don't think you will lift the head,especially now your turboed.


Got any video of the dyno pulls?

Bet you can't wait to try it @ the track!

Good work BTW.

No,the s-trim must be an inside joke of some sort. After a few quick minutes of research it is a F1 trim.

We will not drive it on the street. To many stupid poeple on the the road texting and stuff.

There is a video to youtube a few post up.

Yea, were ready to make some test passes.

I have not looked lately but Turbonetics used to sell an "S" trim wheel I thought you have that turbine wheel? No inside joke.

Probably An F1-68 wheel?

Sounds great on the dyno!

Are you going to run an 1/8 or 1/4 mile?

They do or did offer a S trim. The F1 is the newest wheel used.

For right now we are going to run 1/8 mile till we can sort this thing out. Maybe later on down the road we will make some 1/4 mile passes.

That is AMAZING!!!!!!!!

Why does it sound so good with a turbo? A lot of turbos I've heard don't have the growl like yours does.

And this might be a stupid question but what block and head is that? And what internals work did you do to get it to withstand all that power?!

AMAZING ride man... I'm just speechless...


69 Buick Special Deluxe. Intercooled Turbo Chevy 250 @ 15psi on a stock long block. It's kinda fast.

Mighty6,
I have seen on your website, the extra head bolts added. But thought at that time you went to 6. Where does the 7th bolt come into play? Pics

Thanks. I not sure why it sounds that good. It may be the sound bounceing off the fire wall or the straight cut gears driveing the cam. I'm not sure it could be anything.

The block is just a standard 292 with a ton of mods for durabilty. The head is a Sissell/Kirby that flow really good. A big solid roller for the cam. All the rest is standard race car stuff.

I think the one you are missing the stud under the spark plug.

I'm kinda intersted to see if anybody else has head gasket issues. Our findings are the deck of the block was the problem not the head.

Mighty6,
what was wrong w/the block surface?

Douglas only has 4 bolts per cylinder.

So Far I think the engine has seen as high as 27 PSI?

I would not say that the deck surface is bad. Seven head bolts made it alot more stable. The cylinders go out of round easier without the extra bolts. Well, they did on a nitrous motor Now we have the turbo it may not even be a concern. Only time will tell.
