I am sure it is a great kit regardless of nomenclature. A good 450BHP will make a noticeable difference in driving and response. We tend to be a bit difficult here as you said, don't be discouraged and hope to see you more often.

That is a good combination. The cat delete will help spoolup. The larger turbines will be a great advantage on pump gas. The lessor back pressure helps reduce detonation.

On 93 oct this setup will have no problem making 450+HP. The additional cooling from the IC will help control detonation as well.

I would not advise running california 91 oct on any turbo car. If you blend in some 100 oct this kit will have no problem hitting the 500hp mark.

Remember a factory 430hp full weight 993tt was tested by Sport Auto
0-125mph in 13.5s, so 450+hp with Motronic power curve like the factory's will be very quick. If you read back to when my engine was running an RS engine dyno verified Motronic/twin plug 465@5000rpm and 470hp peak to 6500rpm, it felt plenty quick. Going north of 500hp (as measured by Porsche/Ruf/RS/Maha with experienced operator/Kevin and new toy ) requires cams and bigger than K24 (compressor) turbos. Still looks a decent kit 'tho and no doubt would smoke some other tuner's 600hp.
BTW according to my testing, this intercooler will help control detonation, but slightly "worstely" than a stock one

Besides a handful of enthusiasts it would be pretty accurate to say that 99 % of Porsche, Audi turbo owners plus high compression Ferrari/Lambo owners as well run 91 oct on the west coast.
It might be news to you but the manufacturers with the help of Bosch are able to tune a car with pump fuel all day long and still meet their advertised Hp ratings.

But the four letter supa tunah likes to use racegas for obvious marketing mustang dyno reasons.

I'm not sure what your point is. I think Porsche's idea of pump gas is 93 Octane. At least that's what it says on the gas cap door of my car.

SPR,
Didn't your Father-in-Law buy this off Ebay?
If so what gives???
I was a little interested but am now a little leary.

The 993tt was designed for use with 93 oct fuel. There are basic formulas that dictate what CR/boost/oct combinations you can run. You are suggesting that in tunning that you can turn up the boost and turn down the octaine? Sure by reducing the timing. Guess what happens then. EGT's go through the roof.

The 91 oct california fuel is NOT the same as blending 93/89 from other states. The 91 oct california fuel is blended with many chemicals that don't respond well to boost. There has been lots of research done to support this.

For all of the money that is spend on these cars the additional cost off blending race gas is minimal. The margin of safety that it adds is worth the price alone. Those who think they can increase boost/performance without addressing the fuel issue are asking for trouble.

I thought the guy picked it up evidently not, hence my initial comment about deadbeat bidders, as it actually pissed me off that he would back out. It had nothing to do with anything with the kit at all but tax pressures and some other things.

Guys im not getting it.... why is the HP for all this so consertive compared to my setup (with lousy CIS) single k29, gt2 cams and b&b headers and I am meant to be getting 460 (and maybe 550 when I go Efi).... and this setup wont go much higher than that.

TB993tt

THis bit (and maybe 550 when I go Efi).... is part of the answer. The second part of the answer is to do with Motronic control vs what you have now, the Motronic creates a fat power curve due to the overboost allowed in the mid range at aroun 4-4500rpm which can mean a 460hp @6000rpm 993tt has over 400hp by peak torque by virtue of the Motronic allowing the boost to build until the onset of knock. It is this shape curve which means a 993tt will blow away your 460hp 965. My 1420kg 965 with similar mods to yours and 460hp was tested by a magazine 0-100mph in 9.8secs. A 460hp Motronic 993tt, like the one Kevin does will hit 100mph in under 9secs.
Your 550hp with EFI may be possible as a peak, personally I again would say not if measured on a Porsche/Ruf/RS engine dyno or a Maha chassis dyno by experienced operator. Your EFI would probably give you a more responsive engine, but you (like the 993tt) are limited by heat and going over 520-530 hp on a 3.6 993tt takes expensive intercooling. Of course if you want to build something which shows its 550hp on a chassis dyno run, thats a different story.

Miles965uk

Thanks TB- i wasnt ever thinking my setup was anyway better- as I want to aim for a TT setup anyway.... that was my point- you cant just say the numbers thats why i was confused and new something wasnt right - like you say its about the curve- afterall why should it be!

My 97' has the same turbos (5324-101-5076), intercooler, high flow mufflers/cats, chip, tuned by Mike Levitas at TPC. It made 437 RWHP on a 93 degree day.

A Dynojet run hp is not same as what we are talking about above. IF you have a real interest in how much power you have, seek out a reputable Maha installation and prepare for disappointment, if not then enjoy your car, like I said 460odd hp is very fast in a 993tt
