Power gains on these mods

**ramairWS6** · 08-03-2007, 02:21 PM

hi,
can anyone tell me what power gain i can expect (not absolute,but ball park figure) by adding the SLP loudmouth system,SLP smooth lid and an LS6 intake,on a 98 ram air.
I have already added a K+N,de-meshed the MAF,and cut short the EGR pipe into the LS1 intake.
I recently had my WS6 on a rolling road,and i am not sure if the figures are correct.it quoted 406bhp,but i am not sure if this is flywheel,or RWHP.
Any ideas?

about 20 rear wheel horsepower.

No way your at 406 with those mods. I'd guess maybe 330 RWHP

i didnt think it was correct...........
judging by the figures i have seen on other t/a's it seemed too high!

so would that mean my figure of 406 is flywheel power?

No I'd guess maybe 350 to 365 at the flywheel and that's a high guess. What do you mean by rolling road. A Dyno??

How could it be 350 flywheel hp when these cars come form factory with 345-350 flywheel hp the 325 rating is underratted, i would say with those mods like 365-375 flywheel hp which is like 320-335rwhp.
