Funny thing about that. If you review posts from me from around 2002-2003 on thirdgen.org, I did a lot of testing with intakes. (I'm the EFI intake moderator). I ran stock TPI, aftermarket TPI, then ported TPI. Car was running 110mph with the ported aftermarket TPI. I swapped in a singleplane EFI intake that I made, with a monoblade throttle body. Made no other changes to the car, other than re-dial in the fuel ratio for the new intake. Car picked up 10mph, and now was trapping 119-120 mph. I think I had like. $250 into the intake. Why was there such a huge increase? My guess would be the long tube intake was holding me back. 224/230 degree cam, pulled to 6,000 RPM. Out of scope for a TPI intake, car probably just made SO much more power from 4500-6000 RPM, it showed up on the timeslip. Would you see that on a stock cam? No way. The LTR vs miniram and all that is geared more towards final combos. Guys putting minirams on stock heads and cams are not going to make much more if any power. -- Joe |
