500 wrhp tpi
Re: 500 wrhp tpi
You're very naive if you see it that way. You don't think a 360TPI/Superram would make 500rwhp on 150-200 shot?
Take the run I POSTED. 7.15@98(and that was no where near my best)
It calculates to this:
Your HP computed from your vehicle MPH is 537.52 flywheel HP and 483.77 rear wheel HP.
And no... grandma couldn't get in and out of my blue car. Too much cage... It won't be made to go get grocieries either. Not it's purpose.

Re: 500 wrhp tpi
Well, if so.... your whole arguement is void. I NEVER stated it made 500rwhp NA, NEVER.
I'm not naive and understand much more than you obviously think.
And, Big-G, OK, and you can build a motor and put it in a turd and it will run, or a turbo on a turd and it will run, or a supercharger on a turd and it will run, or the list could go ON and ON.
Anyway, I'm done with this thread. Besides getting totally off track yall have not helped the OP with his goals at all. You have simply filled this thread with BS, put-downs and "hidden facts" that no one has seen yet.
ps, Big-G I do like your combo...

Re: 500 wrhp tpi
Explain your self better then. I'm obviously not the only one who missed you pointing out you used N2O. Being around the forums so long (
) you should know how this stuff works. I don't think anyone is disputing forced induction is the way to go, in fact you've all but solidified it.
Sorry man it just smells funny so I'm not eating it. Just a little thing I do to keep from being bullshitted too much in life. Honestly you come in making claims like this you should be ready to back them up beforehand. That's just my way of thinking I guess.

Still a good combo anyway you look at it. On motor its still a decent running setup. Probably bottom 12's which is quite common with TPI/heads/cam setups of those cubes in thirdgen fbods
Re: 500 wrhp tpi
My appologies if I missed that, but i saw the post where you said 479 and 500 hp but did not mention rwhp or fwhp or with nitrous or not... i assumed flywheel at first, but when you stated rear wheel I was shocked...figured there had to be FI or N2O involved. I have no doubt those numbers were made tho with a 150-200 shot.

Re: 500 wrhp tpi
whp or crank? I think by the times its close to the low 300's whp mark...typical of those type heads/cam and TPI setups...more hp with the superam due to its higher flow and siamesed runners.

Re: 500 wrhp tpi
Realistically (to answer the OP's question or at least ponder on it) 500 RWHP looks like just a number, but that's a HUGE chunk of power. I've had a few friends that have made this kind of power, but N/A they're usually only sitting around 420-430RWHP in a real stout build at the most. You'll see more sometimes, but that's very rare. I know one friend of mine hit 505RWHP naturally aspirated, but that was in a 408 LSx. That's not your average build, and he had everything done to it that you could do. Lots of money invested. The other had 640RWHP with a turbo 4.6 4valve, and that car was just retarded as far as driving it around. Something like that is a DEATH MAGNET.
I would say 350RWHP-430RWHP (out of a smallblock N/A anyways) is a good goal to shoot for, but anything higher than that it starts getting fairly difficult and very costly at a very steep pace. Even easier to attain though if you've got a power-adder. Also take note that you can make 500RWHP all day and have it be completely worthless. That Cobra my friend sunk all that money into was FAR from friendly to drive.

Re: 500 wrhp tpi
That's what I'm talking about. I can put around town and other than the whine, you would never think the engine had any *****. Blowers rock! My neighbor has an '04 Cobra putting down about 800 rwhp. Beat a turbo Hyabusa up on SH-130....Saw the far side of 200. Gets wheel-spin on D/R at 100. I won't ride with him...ha ha.

However, I like a little rumble..
But that's me.
I'm not a fan of "tame" but then again, it's only a warm weather weekend car. Last edited by InjectorsPlus; Feb 7, 2011 at 05:51 PM.

Re: 500 wrhp tpi
Oh, it's got a "little" rumble. 3 inch exhaust with Hooker Max-flow mufflers see to that, the cam is 244/248/114*...so it lopes a bit.

Re: 500 wrhp tpi
Post 1 and 22 state that he is looking to go turbo down the road and makes it clear he'd be happy with single turbo with 450-500whp. He just wanted to know if 500rwhp was possible on TPI but didnt state it had to be n/a. We all were quick to point out its highly improbable that it can be done without a power adder.
Details on other builds? maybe not...but any build with TPI making that power would be helpful here

Re: 500 wrhp tpi
So I'ts gonna look like a TPI...'cept the turbo...No2 would be less obvious.
I think the thread is that of a circle master and he baited all of you in.
