That RSR has a taper nearly down to 2 1/4 in it, get rid of it and get a tanabe touring medallion, no taper and just as if not quieter, also get a rre rally cat, its a resonated test pipe that is super quiet qhile being straight thru

Invidia TB exhaust and downpipe

AEM cam gears
Perrin MBC
XS Power exhaust manifold
and now my 20g.... So am I going to get above 400 or not.
Are you talking about the BR 20G-LT specifically and producing 400WHP on pump gas? I think that it would be wise to upgrade your fuel system with a 255 LPH Walbro fuel pump and a set of larger injectors(might as well go 750's or bigger). Do an O2 housing upgrade as well, to compliment your header, turbo and full TBE. Meth(not, however, U.S.P. methedrine) will make it easier to reach your desired goal.

Try getting a tune or I hear Vishnu's ECU Reflash works, its 380v reflash is 380 horse power to the flywheel with just the reflash. And if you have more mods which you do have, they tune it to what you have on your car. Try checking them out!

boltons + cams + 680cc + 102octane + 23psi...I tuned it and did 400awhp/400awtq on my friend's car, rough conservative tune -relatively simple.

You shouldn't need the cam gears.

Is the 20G you're talking about the EvoGreen? Because if it isn't you're not going to get that 400whp on a Dynojet number.

With all my bolt-ons, I am hoping for 330whp on a Mustang Dyno on 91 octane. Now, this would be about 10whp more than other EvoGreens on 91, but I have every bolt-on conceivable (short of engine work). Don't know if I can hit that number, but it's good to have a goal

unfortunately it's not the green..i f****d up buying the turbo...so im crossing my fingers for any where around 380-400whp..right now im pushing 346whp 344trq on 100oct tuned for 91 on a conservitive tune...so hopefully when i tune for 100oct aggressively it'll be close

Go with the GSC S1 cams with a custom tune and you'll be close to 400whp
