Title: intake throttle body ?
Post by: svtbird on February 28, 2006, 11:02:45 AM
1st ? Which one yields more power a aftermarket cobra intake upper and lower or the typhoon performer plus. also would a 70mm tb cause any problems since im runnin a speed density set up.

I think the 70mm is a little to much with stock HO+SD.But thats just my opinion,The intakes are both good but you would yield more with more cam with them than an ho of course mass air.

That Throttle body is a little much for stock HO cam and heads.  It'll work with speed density though.

Read these, there's some good info in em......

From experience I know speed density is pretty intolerant to any modifications . It takes a alot of mods to really even need a 65mm TB. If you have the stock cam forget about it.;)

you will need a computer that is set up for 24 lb injectors. You are talking mass air computer right there. It will run, but prolly like ass.

E-cam has 112* lobe separation.....might have idle/vacuum issues.  A lot of speed density guys go with the Crower 15511 cam.  Just something you may want to look into.
