Thread: Modding to 300 hp

So.... Back on topic... Headers, rockers, 3.6" pulley and overkill tune? Got it! Thanks everyone!

Skip rockers.

Man up and cam it.

And run a 3.4".

And reap even MORE gains.

Skip overkill tune -- try WBS

I stayed right next to a 300hp trd Camry when I had 1.9s, ic, 3.4, headers, 3.29 gears. After shifting into 3rd I started pulling ahead then we let off.

Am i at 300 or over with my current mods?

3.0
SD Headers
AL104
180 tstat
PRJ Wires
42.5 Injectors
ZZP Stage 2 Intercooler

I raced my friends brothers GXP and we were basically dead even but he did SLOWLY pull on my top end on 1 of 3 of our runs.

probably.

Why WBS? I thought overkill had the best shelf tunes?

I think i am because 2 of the runs i pulled away from the GXP on top end and left him by 2 1/2 cars... I went to the track last week and stayed next to a 2001 z28 camaro i raced. He had intake only and he beta me by 1 second.

Both are good. Most people just shun Intense and ZZP tunes, is all. Overkill has a weak service reputation (hard to get a hold of, slow work, etc).

I have literally zero experience with Overkill PCMs so I'm not going to tell you anything bad about them. The only thing I'd tell you is to research WHY people say they are better than any other canned tunes. If there's just a few posts of people saying how much they like them and then 50 people read that and are all of the sudden posting about how great Overkill's PCMs are then that's not real data, it's a bunch of people passing information on second hand. Something tells me the amount of people recommending Overkill PCMs out numbers the amount of people that have actually gotten Overkill PCMs. :-)

That said, it might be the best canned tune. Just make sure you get some solid facts as to why.

But an L67 that makes the same peak whp as a LS4, with all things being equal, will beat the LS4 car.

You're like the guy that calls a girl fat and then when she takes offense to it you tell her you were just joking. There's nothing funny about it. I don't get the joke and there doesn't seem to be anything good natured about the way you try to set people up. All I see is someone itching for a chance to show other people how much he knows.

And the fact that you like me is irrelevant to me calling you out. Just stop what you're doing. Three days here and I already have your number.

If a pullied, intercooled, exhaust car isn't making north of 275 FWHP...especially on a 3.0" pulley...I'm gonna say...hmmm...get a solid tune. But, figure in drivetrain loss...you'd be around 300 or more CHP.

Rynoman made nearly 250 FWHP on a 3.4", DP, tune...etc...back in the day. So I'd hope .4" of a pulley drop, a full size IC, and headers, and a good tune would make more than just 25 HP more...even at the crank(should be good for nearly 300 WHP IMO)...since most stock GXP struggle to put down 260~ FWHP from the factory.

right^^ i was saying 300+ hp at the crank for that guys set up

I just had mine dynoed. Same mods, came out to 270 FWHP 295 TQ with the 3.0.

Raced my buddies gxp and slowly pulled on him. he had an intake. I had headers, intake, tune, 3.5 pulley. Its damn close though.

Boost is the replacement for displacement

You can still boost a 6.0L, lol. Or a 5.3L in this case I guess.

This guy knows whats up!

Whatever, you can boost bigger displacement engines. Just not in the case of the lame LS4.
