How much power will the 3.3 TT make?

[Dr_jitsu]

I have been in the car scene since Dinosaurs roamed the Earth. We used solar fuel back then Seeing the infancy of modifications to this motor reminds me of the Porsche Metzger and Supra 2JZ.

Early on we thought that there was no way to safely make 600 whp on these motors (I am more familiar w/ the Metzger). But well tuned cars did just that, made 600 and ran fine for 10 thousands of miles. Then it was 700, then 800. My old GT2 made 800 on C16 when I sold her. This is on a stock block/bottom end.

Same with the Supra, 800 easily.

What is the potential of our 3.3? How strong is its bottom end? Could it handle some huge GT35 turbos? I have little technical knowledge of this motor except it is undertuned.

So far 630 whp is the highest verified number.

Was this in Korea? What kind of gas and boost levels? Is this a car that runs daily, or is the 630 a peak dyno number. The Metzger has better torque than the Supra (relative to H Power) but the 3.3 is by far the torgue-y-est. If this car could put 500 hp to the wheels it would be competitive with the bigger dogs. It is already making crazy torque numbers just from tunes. I've said this before but this car is generally faster than the HP numbers because of torque and its huge powerband.

Correction, it is 650whp.

Daily 650whp with big turbo kit (spool up around 3000K RPM), 93 octane gas.

Will definitely follow.

An acquaintance of mine has been using his car for over 20K miles without any single trouble and he is doing 620WHP on the dyno. He drives his car everyday in traffic, highway etc. I sat in his car during a little drive and it runs like a charm.

so far from what I gather the weak point is somewhere in the transmission/diff when launching these big hp cars, the engine seems rock solid, no one has found the limit yet.

@xot1 - are these guys running lap3?

 

[xot1]

Yes most of them, but not all of them.
Up to now there are 8 cars with big turbos making over 600WHP.

 

[Regs120]

Are there turbo kits out there now? I don't wont monster numbers - but turbos more like the Red Sport Infiniti would be nice.

Looks like Lap3 is "close" LAP3 Turbo Upgrade R&D Results


Stock PSI on larger turbos looks like it hit the sweet spot at 500-550 whp with a flat beefy torque curve. Anything more you run out of fuel. Who knows how much more stress this could add to a system made for 300-350 whp. The drivetrain would likely be the weakest point with the half shafts and transfercase.

This is going to be my new favorite watched thread

Lap3 has been "close" for like 12+ months.. I wouldn't hold my breath..

 

[Regs120]

Yeah, it probably just a publicity/viral media stunt. Speculative until you actually see it on the road and in production.

Yep, a little research has suggested this. Torque is brutal on these components. I would have cars at this power level as a highway roll on car. Races are typically from a 40-60 mph start. Here in Houston...um, excuse me, Mexico we have something called the Supra nationals and the fastest cars from around the world come. There was a formal 1/4 mile/track/60 to 130/dyno competition during the day. The road course allowed my GT2 to be competitive with the higher HP cars, I placed third one year. However lots of people, the sheiks from Abu Dhabi etc (these guys are so rich they don't even drive their own cars) came out for the night action. There would be lots of midnight roll on action.

As cars became more and more powerful and too dangerous the night racing moved to Airfields. To even get invited to race you must have aty least 1000 whp. Most cars are much, much more powerful.

However, with the powerband/torque on this car, at 550 plus whp this car will be very competitive with 95% of what is out there on the road, even in Houston...ooops Mexico. That low rpm torque gives you a big jump. I've never had anything like it and I have had a number of large v8's. However, on the typical day here, you will see at lest 1 or 2 cars out on the highway with really big power. Today I ran across a modified Ford GT. With bolt ons these cars make 1000 whp all day.

In Korea anyone can call them and say I want it done next week.
I know several people with big turbos, have been in their car, have seen them perform.
This is no fake.
They are just shady about the reasons why itd taking so long to have it for sale on the foreign market (go figure why..)

Sure, I get that. And maybe it's 100% out of their hands. Or not.

I just wouldn't advise anyone OUTSIDE of Korea to wait for their kit at this time based on what I've seen.. Then again, I'm just one more overpaid yahoo on the internet - my advice is worth about half of what you paid for it

You can pick up a used BMW M5/M6 (F10/F06/F12) for similar money as a new Stinger now a days. The 4.4L Twin Turbo put out 560-600 HP stock and run a 11.7-11.9 sec 1/4 mile.
Simple bolt-ons, and a tune adds another 100whp. I'm sure that'll do well at the races in Mexico.

Cool. My GT2 put down 800 rwhp and Supercharged M3 put own 644, but the powerband was short. M5's are great, but you are looking at higher maintenance costs. The easiest/chepest way to build a good roll on car would be a Hellcat with a tune and a 100 shot. That will give you close to 800 on pump gas.

You keep saying “GT2” and it’s quite confusing. I’m assuming you mean Porsche GT2? Because I don’t know if any Stinger GT2s that passes 700hp yet..
