Dyno'd and tuned my BoostLogic IS300 kit

[leoPTE61]

I posted this on is300.net but I'll post it here as well.

I dyno'd and fine tuned my car yesterday. I got a speeding ticket last time trying to fine tune on the highway so I don't want to repeat that mistake.

At 5 PSI, wastegate spring, the car put down 250 whp.
At 9 PSI, it put down a little over 300 whp.
At 11.5 PSI, it put down 331 whp.

I couldn't go any higher because the stock clutch began to slip around 12 PSI. What's interesting is the person that was doing the fine tuning mentioned his EVO puts down 340 whp on the Dyno Dynamics' dynamometer but 370 whp on a Mustang dyno and a little over 400 whp on a dyno jet. I might redyno my car on a dyno jet this spring just to get a better estimate on what the car is making compared to my base line 185 whp I did about 2 years ago on the dyno jet.

^ They had to strap my car down at the rear seats because the wheels kept coming off the rollers. I thought about jumping in the rear seat with my friends to add some more weight but the noise is deafening.

Yup, stock GE VVTi motor with a 2.5 mm headgasket.

just because the numbes are higher doesnt mean that it is a better estimate, i dynoed on a mustand dyno and the tuner told me that i would put down lower then wat the car is making but it would be a better estimate then the dyno jet b/c it over estimates ure numbers and makes you think ure putting down more then u really are, i would personally prefer to think im putting down 370 whp and have an actual of400 then think im making 400 and put down 370

The only reason why I would dyno it again on a Dyno Jet is to have a better comparison of how much of an increase in power I made over stock since my stock run was on a Dyno Jet. It's nice to say my car made 330 rwhp at 11.5 PSI on a Dynamics Dynometer but in reality I drive on 6 PSI of boost so numbers aren't everything, I care more about the fun factor after doing this work.

do you still need engine management weven with the the return line ?

of course, you cannot successfully run a turbo kit on an IS300 without some sort of EMS.....I don't care what anyone says....they are wrong :rant2:

[erollinc]

well sounds like your on par.... my stock 2j put down 300 wheel at 9 psi on a mustang dyno .... tends to be that the mustang dyno reads 10-12 percent less..... i would like to dyno it on the dyno jet as well since thats where my car bone stock made 180 to the ground

it was a t61
