im gonna say 380ish ...ive seen lots of bone stock cars dyno 320rwhp on this board...why is it so hard to believe he got 20rwhp from a lid and a tune....if you hit 400 you will be the 1st.....
you will need good stepped long tubes QTP'S seem to make the most power but expensive....
dual exhaust dumped at axle...
fast 90/90
ud pulley
lightweight alum flywheel..
electric water pump
and a very aggressive tune..
that might get you close the highest ive seen a bolt on car was 390 and it had all that....

my car with a LM2 and an slp lid w/ k+n made 333hp and 334 at the tire. it mph
d between 108-109 with headers it did 112.9 w/ full bolt-ons i think my car is capible of 375ish...those numbers are corrected by the way on a dynojet

I Think A Good (and Ovbious) Point Is Every Dyno Is Different So Dont Focus So Much On The Exact Number Moreover The Improvemnt In Numbers...
If You Think About It My Car Dynos Say 280 Stock And Now 430 (on The Same Dyno) I Can Compare That Difference Much More Accurately Than Tring To Compare My 430 Vs Your 450 Because Theres Way Too May Factorys That Are Out Of Your Controll For Turely Accurate Readings On Any Dyno...

Best dyno for tuning since you can load tune at any rpm you want. Also thw most accurate due to the direct link to the driveline. Every dyno pull I do is also set to smoothing 5 also, pretty much the standard for comparisons everywhere.
Id guess a max of 380-390 too... but I guess it depends on how effiecient the parts are being used... Anything that can be used lightweight though would help... flywheel, lower gears(3.23 instead of 3.42, although its only good for FI situations), good free flowing exhuast, etc...

full bolt ons - underdrive pulley = 359HP on my 98.
Headers + Tune brought me up from 306->359 43HP gain.
A cam netted me 21HP.
98 heads are holding my TR224 cam back from that 400HP number...

with just a MTI lid and Pacesetter longtubes, i made 352/360 thru a stock catback. this was with my A/F at 11 to 1.... i could have leaned her out alil more. i have a 99 M6 still with the ls1 intake too. i dont think with all the other bolt ons i would get close to 400rwhp. i put my 12 bolt with 3.73s in and dual cutouts and she dropped to 344/356. i dont think youll get close to 400rwhp with just bolt ons....

The dynapack that I use actually dynos lower than most of the other DynoJets in the area, including A&A Corvette.
As far as getting to the 400 mark, after reading all this, I think it will come close (between 10 and 20 shy of the mark) So I guess I will have to order up a set of 1.8 roller rockers. That should put me right there with all the other supporting mods I will be doing. Im trying my best to match components as closely as possible to get the most gains.
Thanks for all the help guys, and if you want to keep posting what your cars are putting down, bolt-on only... Im enjoying the read.
