Dyno shootout 1200 RWHP Twin Turbo

[utahviper]

I had the opportunity to participate in a dyno shootout. Unfortunately I didnt win but it was something else to see the Silver Supra make almost 1500rwhp. Here is a dyno of mine and a dyno sheet comparing my dyno pull to the mammoth supra dyno pull. Enjoy.

Special thanks goes to the heffner team for building a great car that has taken some abuse but just keeps laying down the numbers. I dynoed the car one month earlier and made within 10rwhp at the same boost level, 15PSI. I was running a mixture of 100 and 110 octane fuel.

Here are some pics that bottlefed took.

Great pull!

On a side note my car is hitting the paint shop next week for the same acr look on my vert with my new 08 hood.

Looks great!

Here is bottlefeds car on the dyno, it was very heat soaked and the temp's were in the mid 90's. I think he had to pull timing so it is certainly not his highest dyno number but his car sounded great and hit hard.

ok, I watched em both... quite boring but to my ears the 600 hp car sounded better than the 1200 hp car???

How much power (and boost level) do you run on pump?

Not surprising that the Viper has a 250hp gap Above the Supra on the bottom end.
There is no replacement for displacement
Any chance you could re-post the graph with RPM's on the bottom insted of mph? Also, throw the Torque on there(you can display 2 things on the same graph with the WinPEP software)

That's the sexiest TT Vert I've seen so far, congrats!

The rpms do not pick up well on my car or the supra. Therefore, no rpm or torque readings. You will notice that not very many high powered cars have torque readings.

Thanks for all the kudos!

I make about 950 at 13 psi with lower timing than what you just saw on the dyno. GT40R turbos(67mm).

very nice and Id put money on your car being faster from 50-135 mph

I do have a couple steering wheels with the red drivers stripe

Doubt that the Supra was boosting only 15 psi ..... probably more like 30.

Looks like your car could use some additional tuning up top.

Would be interesting to see rpms and A/F ratios.

What have you done to the transmission to hold the power?

Chewed up the teeth on both gears (2nd) the other day under throttle in a beefed up T-56. Going to try the new T6060.

Here is the open book on my pig fat viper...I dont mind it being fat because it is safe and I cant hook anymore power anyway. 15PSi of boost at 130mph still spins the tires. I cant hit that boost until 140+. Why would I need more?? I know that this car is capable of 1350rwhp @19-20lbs and a leaner tune but for what purpose? Check out the AEM Log.

I have been through one transmission already. I just use a stock t56 and shift slow and easy. Once this transmission grenades then tr6060 here I come.
