I have a Steg. ported blower, BBK longtube headers, 2 chamber flowmaster catback, Accufab w/plenum, C&L 95mm, LFP heat exchanger. SO with all those mods add a 2.8 upper and a 4lb lower what will my rwhp / rwtq be?

2.8 and 4lb lower yikes, right before it explodes it should hit ~500 to ~520
much higher then that youll have the maf pegged or run out of fuel.

j/k about the exploding thing, well not right away anymore lol :)

well you will 18-19psi of hot air, I ran that combo and car didnt like it. Turned it back down to 15-16


depends on the car and the tuner for the tq should be 520-540, HP will probably be lower due to the lack of efficiency

So will a 2.93 and a 4lb lower or a 2.8 and a 2lb lower which will net the most out of the combo?

I plan on running a 2.93 and 2lb lower... Or 3.0/4lb lower, just because you make more psi doesnt mean your car will be faster!

I plan to run a 2.8/4lb at the track, and a 2.93/4lb on the street. The key is to reduce IAT's as much as possible. A fender mounted CAI like the JLT will do the best job of lowering IAT's along with a good heat exchanger. Another option is the pfab intercooler box.

2.80 upper, four pound lower, Accufab TB, 99/01 Cobra JBA 1 5/8 headers, 99/01 Cobra Bassani o/r x-pipe and CB, nine inch Powerstack air filter and a David Cane tuned chip on the stock unported Eaton. Put over 20k miles on this combo before swapping to a KB at 42k miles.

Ok so I should be good with that combo then? I basically everything you do except I have a ported blower, and a LFP heat exchanger
