Uh, I have exactly 480whp at only 21psi and it cost me $40,000. Soloracer was dead on. I paid to get it there. Tool has tons of hours tuning his car. At 21 or 22 psi, you better be sure the motor is built to handle that. I can turn it up to 24 or 25 now that it's broken it. Gets a little lean up top though but I love saying the number 600. Now, I have stock motronics, so with engine management, you'll be higher but...never mind, everyone else here is saying the same thing.

"it was also off the charts rich is some areas...greatly hurting full boost."

I was not aware of that. I know being real rich kills some of the hp results and can hurt spool up but was not aware that being real rich up top hurt total boost levels.

How rich are we talking though? Like single digits??

But even with a cheater, the point was cost vs. 300rwhp.

Cheater, MAF, chips, WG would get 300rwp, say 18-20 psi, would be under 4K and be 300+rwhp.

I would say not even a MAF would be needed.

You would be lucky to get 300 to 330rwhp out of a 50 trim t04e at 18lbs of boost. That's with all the supporting mods like maf, injectors, testpipe, wastegate, chips. Your in turbo lala land if you think a k26/8 can meet the criteria that I stated earlier.

Silverbullet951

I thought it costed you 200K?


Solo, I'm going by what I've heard from my mech, so if he doesn't live up to his numbers, then I'm sure it'll show that you guys are right. But from what I know now, I'm expecting those figures.

And if that IS the case, that it costs 40K to make 480 at the wheels, then it is definitely NOT worth it to mod these cars. I can get a car which is only 5 years newer, and make 1000 at the wheels for much less than 40K.

Bullet: Welcome to the real world. I have way more than $4K in my 951 and I don't even dream about getting 480 RWHP. I also own a 93 RX7 and compared to the 951 it's easy as pie to get more power out of it. In the RX7 world 400-500 rwhp is much more common than it is in the 951 world and it wouldn't cost much more than $10K to get there.

As for your 1000 RWHP for under 40K I don't think that is easy to do either. For example, a heavily modded Supra Turbo is capable of that but I suspect even it would be approaching $40k to get there.

I don't doubt John's numbers whatsoever... I dyno'd by 951 and was suprised with the numbers I got.

247.1whp, 299ft-lb to the tire... and that's with a split second peak of 16psi, bleeding off to 11psi by 6000! It gets better... my a/f was under 10:1 from 2500 to 4500 psi, and this stock K26/6 motor has 174000 miles on it

In fact... I guess it's time to start a thread and post the "interesting" numbers that I was happy to see from a well-used 19 year old car with a horrible tune.

sorry it was a typo. I ment to say turbo spool up. I was saying it was off the charts rich before fine tuning hurting full spool.

I actually generate more tq and hp lower in the rev range now. Jimbo was making a comment about the slower spool and everything. I get full boost by 2900 rpms in 4th.

Ofcourse like I said all this is a mood point. The car is slow and always will be. Our cars are ment to make alot of hp. It costs alot more to get 400whp outta a 951 then alot of other cheeper alternatives.

To silverbullet if the guy said he would get you 480whp and is only going to charge you 4k even if it costs him 20k then hell take advantage of it.

I do have a lindsey head on the car now and a few other things since the 301/341 dyno way back in late 04/early 05. But, the engine could use new seals and the turbo is tired now. I have been looking to upgrade for a long time now(nothing new) so hopefully that happens this year.

I think 380-400hp in a 951 is more than enough to have fun with. Our cars will never be the fastest thing out there. Its just simply old technology. There might be a few 951's on here that run very strong and make good #'s but, most of us have around 300rwhp or so......which these days really aint ****.

I say drive your 951 and be happy. Enjoy the way it responds and fits you. Forget trying to be fast...its a loosing battle.

ehall

That's because he launched atleast 2 similar engines into outer space as a result of improper break in. The rest of his cash spent came from making the car perfect otherwise.
BTW if you think you're going to make a THOUSAND HORSEPOWER at THE WHEELS for 40k, in something else, then you need very much to put down the bong, and seek help.

Silverbullet951

Well I was exaggerating about the 1000 at the wheels..lol, but I'm just wondering, what could possibly cost 40 thousand dollars to put 480 at the wheels on these cars? I was little conservative with the 4000 I said would be spent. It's more like $6000-7000, but still, 40K? HOW? Tell me what else I need to install. This is what I'm looking at so far. Mind you the engine runs real strong. Turbo: $1500-2000, Engine management: $1500 Exhaust: already covered, Injectors: $500 (just an estimate), Wide Band O2: $500, Wastegate: $500, Labor, install, and tuning: $2000. At the most I'm paying 7000. We might go for cams and head porting, which I was told would be an extra 2800. And even then, I'm at 10 grand. I mean, am I missing something here?

jgporsche

This is a total, without a turbo(Vitesse St3 $2000), head work ($2000 AT LEAST), headers w/ crossover, SFR of course ($2700), Cam($500-$750), Don't forget a new clutch to handle the power, lightweight flywheel, larger wheels and tires to keep the power on the ground......... the list goes on.

A.Wayne

Yeah but a that power level you get to run that RX7 thru the gears one time ! before making a trip for more apex seals.

I find it hard to believe that it is just a matter of bolting stuff onto a 951 and get as much power as 480 rwhp. I would assume that it will take a lot of time to get there with all the tuning.

ehall

On the engine in question for 40k you are missing exactly eight extra valves, among other things, not to mention another .5 litres. Even the strongest 2.5l turbo on this board, that dynoed at 533 hp, doesn't run over 380 hp on a day to day basis...and he does ALL of his own labor. DEFASTEST 480 is at a boost level that the car was specifically designed for, so it makes this power with not too much effort. Your 2.5 won't get close to that without a HELL of a lot of effort, PERFECT TUNING, and a LOT of boost. It won't be sustainable.

i pretty much hate name brand "kits"

on my GTI right now i have a used chip (GIAC) with ebay DP+home made catback, and 5 degrees advaced timing. i payed $425 for it all (plus shipping and installation of the chip) and was making MORE power then whose who were buying the $700 apr chip, $1100 turbo back exhaust, $100 intakes. and $300 boost controlers.


i havnt quite got a grasp on the whole maf thing for you guys (i just unpluged mine and i run off a tunable base map.) so im not sure that $2000 maf is needed. but alot of that other stuff is just paying for the name!



any car can be cheaply modded to high HP....but it will lose all hope of relibility. thats the main point im really trying to get across. that and name brands are a waste in most cases.
