Thank you Patrick.

 

30 psi and 540 whp, is it just pump gas?

 

we just received a pleasant email from emp, the driver of Sierra Sierra's evo. one particular part to note:

"On the Power front....wow did we have them covered. I don't think anyone was close to our 298.9 km/h down that short front straight. Thank you Cosworth, Borg Warner, Turbo Smart, Royal Purple, Full Race, And Okada......I can't begin to express how exhilarating that power is." -David Empringham

 

I'll have a better idea once i see the graph later today.

If the dyno is not being used i'll try and get a graph posted up but i don't think it's finished being tuned

Welcome

All tuning is being done on pump E85 as we only have 91oct here in CA

Def sounds like the Evo is making gobs of power

Hope to hear from you tonight or later this week!

 

hey patrick - good speaking with you today. 32.6psi is the maximum inteneded boost level for the single port internal wastegate canister. Sean is obviously on the right track that adding a 2nd barb to the canister is the correct thing to do (in principle) *however* it will be tough to do this to the existing canister without damaging the diaphragm and/or having a boost leak at the bottom of the can. As I mentioned we will have the billet EFR wastegate actuators with dual nipples ready shortly and this will be a great test bed for them. I look forwards to finding out what you guys figure out

 

Speed on the straight is a small part of the equation, maybe with a small turbocharger SSE would have made a better time...
The 9180 is a MASSIVE turbo, something like a Garrett GT42!
Also, the SSE evo this year is very light, they shaved 800 lbs out in comparison to 2010 WTAC!

 

800 lbs lighter? You sure about that as looking back the car was like 2750 last year.

No doubt there is more to it then straight line speed. I was coming from the perspective that they feel response on the 9180 is fine so either the Cyber Evo has some crazy advantage in weight...or...who knows as the SSE EVO is pretty serious business on aero, suspension, and brakes.

No doubt, a smaller turbo could go faster, but I seem to remember reading a motoiq blog where they had the smaller 8374 on and then tested it against the 9180 and the 9180 turned faster laps?

 

I think if the SSE could've kept the trans together we would've seen some blazing fast numbers. Why the SSE Evo didn't wax the Cyber Evo, would probably be better addressed by the SSE team themselves.

 

True...
But are they even on here?

Speculation buddy...
Speculation

What else am I going to do with my time? Work on my car???

 

I suppose... it is the forums...and we're all discussing a turbo we don't have. I guess it's fair game.

I suspect SSE wasn't prepared enough for the setup the car ran at WTAC and they suffered a failure due to lack of testing. For making nearly twice as much power as the Cyber Evo, they certainly didn't hustle the car around the track respectively as fast. Something is amiss.

 

Its not 800 lbs lighter, they said that as a joke because a lot of the other cars are tube chassis and not a lot of stock sheetmetal.

 

If those high speeds were recorded on the final session before the gbox broke, maybe they were on the way to a pants fillingly fast time and the previous recorded times were just an indicator of its potential?

 

Great time attack turbo here!

 

patric i still cant understand, you running 32 pounds of boost and only getting 550whp on E85?
So much boost for such low number, or im just not too familiar with evos..
