I would either build a LS1 427 with the AFR 225 CNC ported LS1 heads or a 434 with CNC ported AFR 227 CNC ported heads.
Thanks !Siggy_Freud said:Lingenfelter builds a twin turbo 427 for their Vettes. I dont totally know what other turbo type setups they do but having seen their actually billing sheet I can tell you they are $$$. The engine and twin turbo setup alone costs $50,000 . . . almost as much as the dang Vette itself.
Lingenfelter.com is their website.
Galebanks.com also has a new turbo setup.
My 350 is 0.30 over, +-420HP (build as edelbrock performance RPM model) , i run whit 150HP nitrous but its not enough to getTurboS10 said:There is not real need to go huge cubic inches with a turbo or supercharger. With forced induction you could not get the power to the street with a turbocharged 305 that was built right. Race track is a little different, but not much. High revving short stroke engines work very well with turbos and they cheaper. A 350 setup properly would make enough power on pump gas to run 10's and 350 parts are real cheap and easy to find. Next time I have to build a shortblock it will probably be a 350 or 377.
The car & rear end can allow mutch over 1000HP i have a moser 12 bolts on it , i just have to make sure i will use the best combo on the engine, since supercharged engine is pretty new to me i want to avoid to get wrong part ...coldknock said:There is no ideal compression ratio for "maximum boost".
Keep the compression 8.5-1 or lower and run as much boost as your fuel, compression choice, pistons, head gaskets, rear tires, and drivetrain will allow. Remember that the weakest link will decide what the boost limit will be.
Good luck fella.
My car is used for street just a little, Most of the time its to go to the track the week endTurboS10 said:Compression ratio is sort of a matter of application......
If you are building a race only engine, I would say keep CR as low as you possibly can. 6.5-7:1 would be just right and would allow more boost on the same fuel. The problem is that with CR that low the engine is going to be a little hard to start and will have no power in the low RPM and before boost comes in. For an all out race car this is okay, but for something street driven it is not.
8.5:1 will give you room for a good deal of boost on pump gas and the engine will start fine. It will also not completely kill power in the low RPM which will make for decent street manors.
