Quest for 500 RWHP Naturally Aspirated

Right now I'm sitting at about 462 rwhp. But that is not enough. I want more. I just ordered a set of Stainless Power 1 7/8 headers and am going to order a new cam next week. Something around 232/244 . What else might I need to get there. Or will that put me pretty close. Also thought about getting a FAST intake and 102 mm tb. What do yall think.

Those mods may help, but might not be enough to get to the "magic" 500 number. I have yet to hear of a non-stroked N/A L99 hit 500 rwhp. 'Not saying it can't be done, but drivability might suffer quite a bit.

have you considered or look into E85? Or upping displacement like fldrummer mentioned?

I havent really looked into E85 but that might be an option.

i know on FI applications it works wonders, not sure what your NA gains will be though, it'll def make more power. Wouldnt hurt to let Mr. Jannetty tune it either

I will look into it. But I have an awesome performance shop I use locally. Thanks

We had the heads done when I got the first cam.

I may not get 500 rwhp but I wanna get as close as possible. I should have went this route the first time.
Zeke. I know what your gonna say.

I'm not sure about non stroked either. My 05 gto had a tsp built 402 making 505/463 at the wheels. Used their prc stg 3 ls6 heads, the prototype for the magic stick 4, fast 90, 1 3/4 longtubes. Still pulled down 25 mpg on the hwy and had decent drivability too.

Lol hey bud it's ok we live and learn.

500+ is achievable. Just google chris1313 on tech. That's my buddy and he laid down 510? On a SBE Ls1! On speedinc's rollers! Thru an auto and moser 12 bolt! It's all in the intake, right cam but mainly in the heads and compression!
Man forget this drive ability crap! If your tuner is good and so is the converter you'll be ok!

I'm thinking a lil bigger cam than the one tour thinking of bud.

Call Ed Curtis from flowtech
Or Brian Tooley from Brian Tooley racing.
He use to own TEA before he sold it to Summit racing.
Tell him Litle88 sent you.
They'll both spec you out the right cam.

Since you are getting the triple disk converter just have them lock it up on the dyno. That with a bigger cam and intake should get you there becuase the driveline loss when locked up is alot more comparable to a manual trans. Just be aware that a bigger cam and a 102/102 intake is going to suffer a loss of torque in the lower part of the rev range. I saw a test of a Fast 102/102 on a stock displacement L99 with Mast heads and VVT-1 cam loose up to like an average of 8RWTQ and HP from 2500-5500RPM, even greater losses below 2500RPM, only to gain 4RWHP at peak RPM. Needless to say they pulled it back off and put the stock one back on because thats not such a good trade off with a street car. Peak dyno #'s are for show, higher average power is for go.

And thanks for the advice.

I just got done replacing a tsp 231/236 with a cam from Brian Tooley.Car has Tea ported and milled ls3 heads,ported intake and TB UD pulley and supporting bolt ons.It made 509/450 at Redline Motorsports today.The cam is slightly larger and I had to flycut for intake valve only.I would call BTR and get his thoughts.Good luck.

Maximizing TQ which computes to HP is a function of cubes, compression, air and fuel.
What compression are you running now? What head chamber size?

If you want to use the stock bottom you have to max out compression and max out valve duration/lift without hitting the pistons.

There is a builder down the street who just built an LS7.....ported heads, high compression pistons (12.5/1), stock crank, custom cam, stock LS7 intake and TB....for a kit car. He retards the timing to offset the risk of detonation.
Runs on 91 octane and puts down 740hp to the wheels....idles really nice.

The kit car runs a viper transmission (T56) and a ZL1 rear end......2800lb car.

We have done 460-480 rwhp with the G6X3, LG LT's, LG CAI, and 3800 stall through the stock trans and diff.

Stock heads and intake manifold.

The FAST, even with the 102TB isn't going to pick up much more than 10-12 hp, and if the car already has a ported head on it now, I would double check CR to see what it is.

I'm also assuming that these are SAE DynoJet numbers?

I had the heads worked when I got the cam installed but cant remember the specification. I thought a bout figuring the CR and looked at the calculator and I said screw it. I sent a text to the shop and asked them to figure it for me. No clue. I just make the payment and put gas in it.lol.

The numbers are SAE Dynojet.

Im also putting 1and 7/8 headers and adding a stall.

When you bump up compression Dont forget you have -2cc valve reliefs on the L99 pistons which lets you get away with either a smaller combustion chamber and a lil more room for PTV with a bigger cam. Just throwing that out to you too bud. And don't be afraid of a lil fly cutting lol.
