Twin Turbo RWHP?

GTS Black · September 17th, 2006, 08:36 PM

How much RWHP do the twin turbo cars get on 93 oct gas?

Thanks

Darius · September 17th, 2006, 08:41 PM

I would think as much as 1000-1100 and as little as high 600's low 7's depending on the motor build, creampuff, or earlier forged motors?

96-99 w/ heads and cam around 800-850 on a conservative tune.
SRT probably about 900+ with the fully built 522
these are just generac twin turbos nothing out of the ordinary

More specialized turbo applications, like the Barrett 106mm single, Paolo's big turbo setups, as well as the newer, big (76GTS +) setups from UGR and Heffner could all probably crack 1000-1050 on a good tune-- maybe more. This is assuming a good engine to start- Stryker heads and and a stroker crank or bore job.

The most we've made on 93 pump gas and water injection is 1500rwhp.

Running the V-10 at 8000 rpm?

Was that for Pump Gas Drags?

LOL.. Thats just plain sick..

depends on the kit, boost, and tuner.

Ive seen the CPE kit make 800rwhp with just injectors, CPE rails and a bap on a 97 GTS with just roller rockers. No other motor work. With a hair bigger turbos, a few more psi, and a little more aggressive tune, I dont see why 1000 would be out of the question for a stock motor'd car.

Without touching the engine, 700+rwhp/tq with Heffner TT on 93.

I wonder how many here read that and let it sink in?

good to see a tuner here gets it! Great job SVS.

Water does not give up its secrets easily - but they're there.

1500rwhp on 93 + h2O

enough said

I bet the boost on 93 was not as high as other Vipers have seen - right Jr?

That would be a very good combo ladies and gentlemen!

Yes, that was for the Pump Gas Drags. We had the power but obviously didn't have the strength in the rear end to launch hard and carry 3950lbs.

Trying to make a landspeed prepared race car double as a drag race car has presented its challenges.

Our side mount TT system (T3 60-1 turbos) on a stock forged V10 will produce around 800rwhp on 93oct @ 8-9psi

It's not out of the question to make the 1000rwhp on a stock bottom V10 engine.

The question is:

After you make the 1000rwhp on the dyno how reliable is that same stock engine with 1000rwhp on the street or track?

**CHAD** · September 18th, 2006, 10:49 AM

But it made it on the dyno. What else is there?

Dyno rules all now, no track or drivability credit even required haven't you herd?

Jr, I believe Dyno Daddy has found the limit of the stock bottom end making 1000+ RWHP.

I would think the main caps would be walking all over the place at those power levels.

Rumor has it Joe Barrett sent his motor to Proline to be rebuilt.

Parts scattered all over the ground comes next.

I found the limit of the stock maincaps. They like to walk after 1Krwhp. I started to see some fine metal bearing flakes in the oil after the first 750 hard turbo miles on the car. I decided to shut her down before I spun a bearing.

I made 1075 on 93 octane, 490CID no water or meth injection and factory casted heads @ 15.0 psi. After I put the main caps in I will aim for 1225-1250 with the same setup but with 19-21psi and upgraded ignition. With the big turbo and huge intercooler my AIT and backpressure are both unbelievably low.

I have about hit the limit with the heads that I have on the car. If I put on a set of Stryker heads I amd sure I would gain another 150-175rwhp on top of that.

The SVS engine makes more power than any 488CID engine I have ever seen or heard of on 93 octane. But they also have a fine laundry list of parts on that car as well. I do not have an SVSi budget so making SVS power is not in my cards.

Is this Viper Alley or Supra forums?
