Look at all that damn torque!

Looking at the numbers, you can see the turbo is just starting to wake up at 23psi. A couple more psi and you're gonna start getting into the oh **** territory. Grats!

I think its already in the oh **** territory. 500 ft/lbs of torque and rwhp to back it up with our car weight is ridiculous.

Shouldn't this be an eccentric performance engine and tune ?

I told Steve I would love your numbers on the 3 rotor lol

You have 100 more ft lbs and 100 more hp at 3500rpm than David's 20b!

Keep in mind its a slightly smaller turbo running more boost.

Allow me to state the obvious, this is some awesome s!$t right here!

Seems like everyone is thoroughly impressed with the TQ numbers as they rightfully should be. Whats the secret sauce recipe to this fantastic TQ number and such a broad area under the curve?

5" dp means you must be on a t6. any pics of the setup? im def impressed at how early it comes in. any reason why the dyno run was stopped so early at 7300 rpms?

Trust me. I asked steve osley to treat the car like it was his. We didnt have the race gas so pump had to do. We are gonna go back in a few months to do a race gas tune. 27-29psi and see what she can do.

Where are you seeing 1 bar of boost? It looks very early...4000rpm?

I agree with thewird...does seem trackable.

How is the transient response?

Great results and thank you for sharing.

Was roller speed used to read engine RPM or was there an actual pickup reading RPM?

That's a bad *** turbo. Huge turbine with a smallish(for the housing size) billet compressor. It suits the high exhaust flow of the rotary.

Hey Carpenter, our numbers are really close. And you are on a 67mm turbo also correct? I need a c16 tune.

Yes, 67mm. Ray Wilson, PFS- 301-874-0611
Try Q16, it's about the same price.

You have 100 more ft lbs and 100 more hp at 3500rpm than David's 20b!
Another low blow for David courtesy of John.

Just realized the dyno plot says 27.27 PSi. I think that explains the torque hehe.

The porting from Rotorsports is the secret sauce

There was nothing hooked up from the car to the dyno. So no boost mapping or anything else. Trust me i asked and made sure cause i was wondering what all those numbers meant. The pfc registered 1.62 as the highest and the eboost2 said 23.8psi. I need to move the places where each read cause of the difference. The eboost2 reads off the compressor housing, and the pfc reads at the throttle body.

And yes Bryan at Rotorsports Racing (the old goat) put his magical touch on the car. Still fusses at me daily for owning a fast fd and going from dyno to dyno to fulfill my dream. AHAHAHAHA. We love you Bryan...
