Dyno Facility
=============
SGP Racing - Veterans Memorial, Houston, TX

RPM/Boost/TQ/HP Measurements(I had him start at 3K)
================================================
3,000 = 05 psi = 400 = 240
3,250 = 06 psi = 370 = 245
3,500 = 07 psi = 400 = 260
3,750 = 08 psi = 425 = 320
4,000 = 10 psi = 465 = 355
4,250 = 11 psi = 500 = 400
4,500 = 12 psi = 571 = 475 (We think the Wastegate opened after this)
4,750 = 11 psi = 571 = 525
5,000 = 11 psi = 565 = 548
5,250 = 11 psi = 560 = 560
5,500 = 11 psi = 540 = 565
5,750 = 11 psi = 525 = 570
6,000 = 11 psi = 500 = 574
6,250 = 11 psi = 475 = 565

Air fuel Ratio was 11.x:1 during 3K to 6K, then briefly went to 12.x:1
Weather conditions at the time of dyno:
1pm today 97 degrees F, 40% humidity, 29.9 barometric Pressure, dew point 69F

yikes at stock fuel pump/regulator, small wastegate (not to mention how did he manage 11psi with a 14psi spring? unless the springs are flipflopped and the one said for the wastegate was supposed to be the one for the bov).. he has alot of room to grow there

good numbers:)

My thoughts exactly. LOTS of potential with 8.8 compression and cooler weather coming.

[Fastbird]

Two things I could think of for only making 11 PSI on a 14 PSI spring. Intake or exhaust restriction.

Good solid numbers none the less.

looks like some really nice results especially with such low compression and the temps

I would strongly suggest to him to get a pump in the car before he see that inline give up.

why a 4.10?

Yeah, he should get twin intanks... maybe think about a meth kit too for the higher boost levels. The 4.10's were in the car already before the turbo kit.

[Speed Inc.]

figured the gear was pre turbo build

twin pumps would be a very good investment for him

take care

Great numbers! Do any of your turbo kits allow the car to keep the AC?

yes, he builds them to your spec... a/c no a/c, power steering/no powersteering...

that's the great thing about Jon's kits, is that he will build them how you want them

Exactly!:devil:
