A stock cam is OK to used for a turbo low performance set-up.
For a supercharger,,they do not breath very well.
On my Moms 1973 completely stock 250 Nova. It would change gear @ 4800 RPM. Factory setting for the PG it had.
As far as a blower having a load on the engine @ all times,the factorys have been using a vacuum opperated valve for years that reduces pressure to the engine & less load on the engine.
Whipple has them also as others do.
Ford SC Thunderbird factory V-6 had them. For an example.
Nitrous is much worse as far as shock load to an engine,very easy to break parts.. And more likely blow head gaskets.
As I stated earlier,use a methanol injection set-up!
I also recommend a knock senor install,this will save your engine.
Read up on them when you get a chance.
http://www.alcohol-injection.com/water-injection-kits-1/http://www.jandssafeguard.com/I will state again,,,I see normally 21-23 PSI on my Stock longblock Syclone, stock compressor housing I machined for a larger compressor wheel. Looks "stock" right?
cast brittle hyperutectic (SP) pistons that will self destruct in seconds, as do the factory LS1's.
With methanol & a knock sensor installed to pull out timing when detonation occurs,those 2 items alone are worth the price to save your engine.
My friend is a distributer for J&S & he can set you up w/what you need if interested,plus you can use it on other cars if you decide to.
http://www.american-pi.com/corvair/corvhome.htmlIf I did not think these products work I would not say a thing about them. I have first hand experience with both items,I just use a non progressive Aquamist 1S system.
http://www.aquamist.co.uk/cp/sys1/sys1a.htmlAs long as you can prevent detonation,it will work period,as far as you wanting to turn to 5000 RPM,the stock camshaft most likely will not agree w/that. ;-)
Also,again,just because a person would read a supercharger or turbocharger book stating the piston should have a thick crown .250" minimum top ring down the bore,does not mean you absolutly need to.
As I stated before & I guess I need to again,I have standard 307 TRW forged pistons in my engine,the top ring land is in the standard ring package,(not .250") down from the top of the piston).
I have used anything from a NOS nitrous "cheater" kit minimum 150 -175 HP jets,, minimum engine size 350 CI (for the use of this Cheater set-up)
I will tell you ,it rattled/detonated soooo-bad I thought the pistons would have blown up in seconds,,,but they did not.
B.T.W.,my car never felt so fast,,,,& it was detonating like mad @ the time I used the NOS,my front end of my car raised about four inches higher & it was hitting the top out "A" arms snubbers & the steering was really light!
After Nitrous,I used a 194 cylinder head milled it,ran 12:1 compression,after that, I fabbed & installed a Paxton supercharger set-up blowing through 3 48 MM DCOE Webbers.
Hope this helps any ,I have 1st hand experience in different engine combos,cams,blower,nitrous etc.
I do not claim to know it all,but I have done a lot w/my 6 cylinder.
BTW,the 307 forged pistons & original shortblock are still together still in my car & never fresheded it up.
For my next venture,I will install my SPA turbo manifold,Turbonetics T3-T/4 hybrid 62-1 turbo EFI,onto the same shortblock that has been in my car for yeeeeears,just to get used to the EFI stuff & tunning,then I will build a nice designed longblock engine specifically for a bigger turbochager.
Thanks for your bandwidth.
All these differnt things I did to my engine all took place in a couple weeks time,,,,,,,,,,,,,,,just kidding.
Most all the transitions/work done was when I was single,no kids, & had help from my friend that knows cylinder heads & much more.
