Will this suck too bad on the street? Hey everyone,
I'm not looking to break records or go too nuts, so I put together a combination with spare parts and budget friendly options. I'm just worried it's gonna be super lazy out of boost and would like some input.
The engine is an LQ4 based 408ci. (4.030/4.000) using a -27.8cc piston and a .221/.224 .600/.600 camshaft. The heads I have are CNC'd 823 castings. I don't know the exact chambers, so I'm going to say 68.4cc for the time being. If I went with 0.051 gasket, my CR should be around 8.8X:1 (pumpgas/meth friendly)
The car will have a relatively small 8085 T4 flanged turbo on it, and will probably spool at a reasonable rate, but it's a dual purpose street car and I don't want to be stuck in the slow lane out of boost.

Vehicle weight and gearing will play a big roll too. No reason that setup shouldn't make 400+hp NA @ 8.8:1. Everyone's definition of "slow lane" is a little different though. What size t4? What turbo has an 80/85 wheel combo?
