That thing must be a ******* monster, considering the weight

Look where the boost starts, damn near off idle https://www.nopistons.com/forums/pub...IR#>/smile.png We started the pull at ~1900rpm. I think this turbo is a pretty good size for a stock port 13b-re. Boost in the low revs and pulls to the top.

NICE numbers for only 12psi. What is your boost controller set at? Now take it to the track and put it on a scale. One day we will meet, at a track I hope. It must be nice to see your hard/nice work pay off.

Nice#'s, I hope to get mine tuned this weekend.

Very Nice curve Setzep!!

That turbo spools like a MOFO!!



I can't wait to see higher PSI Numbers.



EDIT: Okay, I noticed you were creeping to about 15 PSI.

I thought you had fixed the boost creep?



So you are making 295 at 14/15 PSI?

Still Damn good. Get some race gas and go for 20+!



I should be re-dynoing mine with the Haltech in a

month or so.

Thanks guys!



The boost hit a max of almost 12psi as seen in the TQ/PSI graph above. Peak power was exactly at 7k as you can see in the HP/AFR graph below. You can also see how the rich AFR's were hurting my power.

Now I'm really wishing I had put the higher pressure WG spring in for that night. I don't run a boost controller so I had no way of safely turning it up while I was at the dyno. I guess it's ok though, now I know what my car makes on low boost whether I'm picking up groceries or headed to work everyday.

I hate to Disagree, but look at your exact Dyno sheet.

I highlighted it so you could see it clearer.



Your PSI peaked at 15PSI at approximately 6500 RPM.

DirectFreak,



Your looking at his torque in Ft.Lbs line (230 Ft.Lbs -ish) left scale. The lower line is his boost pressure (11~12 psi) right scale. The other dyno graph is HP and A/F.

Okay - thanks for clarifying it.

I am used to Dynojet dynosheets.

Just for comparison Set, I'm running the same turbo as you are, TD07-25G .. dynoed at the end of last summer .. 371rwhp@14psi...

This was on a 3mm motor with a very small streetport (might as well been stock).. 70psi compression numbers.. the motor wasn't the strongest..



the motor has just been rebuilt and now runs 2mm seals and a muhc larger port job.. we'll see what kind of power diffrence it makes once I get it broken in.. however, looking at your hp and torque curves, they are very similar to what I saw on my dynographs..



With a car as light as an FB, I'm sure you car is quite a bit quicker @ 293rwhp than my heavy boat @ 371...nice goin..
