380hp/330ishtq. 27.5psi.

Limiting factors:
85* weather
2" hotside piping
92 octane
VICS manifold
2.5" preturbo intake piping.



Timing map of retard. 7* at peak power



And log. 291kpa



This was a glory pull. Quite questionable on the street/track. Too much boost, not enough timing. But up to about 20psi it was making solid power.

15psi is ~300hp. Great on the street.
20psi is ~330hp+. Great for mexico runs.

 

Congrats- Didn't blow up!

 

Beast!

 

Rad!!!

 

Looks like tons of fun, enjoy! Nice to see a different thread in this section.

 

Nice numbers, what a beast. I'd love to see the same pull on E85, at that much boost it'd have to be mid 400's... assuming it didn't scatter drivetrain bits all over the room.

 

thank you for finally doing this.

 

27 psi on 92 octane? How do your ***** fit in the car?

Amazing results tho.

 

They get knocked into the seat by all the det.

In reality I ran single digit timing, and still made power somehow. Its not a "safe" tune. I need e85 for that.

More of a "what can we do thing"

In the winter I'm going to go back with e85 and see what happens when its colder outside.

 

450 on E is not even a question, but I am genuinely curious if you'll hit the 2" piping choke point past 400 like we're all theorizing

 

Me too. I'll fab up a 2.5" hotside pipe, and a 3" inlet pipe before I go.

Its really tight on space though. The compressor housing has to be clocked in just the right way, which leaves not much room between the compressor outlet and the subframe. I may try and trim the shelf if I have the turbo out anytime soon.

 

Most of the gains on E85 don't come from ingesting more air, they come from using that air more efficiently. More timing means more combustion energy turned into mechanical energy, and burning more Hs instead of Cs means that you get more energy per input O2 molecule. So at the same MAP target, I wouldn't expect the 2.0" vs 2.5" intake piping to matter.

Of course, Aidan could turn it up to 35-40 psi...

understood and agreed, but that wasn't my point.
we all know he will gain power, but if certain parts are going to choke real hard, his hp per psi and/or hp per degree timing ratio is gonna change from pressures spiking and heat building from restriction

 

I was at 7* of timing at 27psi. Anything will be an improvement lol.

 

Fun fact. AIT was 81.9*F at the start of the pull. 89*F at redline. and 91*F shortly afterwards. Precision 600 is BEAST.

 

Loving all the data.

 

Yes, and so is the turbo

 

Hell yeah! Loving mine. Fitment was not too bad.

 

My timing map looks like ***** stuff compared to yours. Running nearly single digit...at 10psi...on a 6258...

Congrats, car must feel amazing.

 

So glorious!!
