Aftermarket Turbo Options

[Handguns4heaRTs]

I like the turbo a lot. On mine I hit 28psi at 3750 RPM. Peaked at 29psi at 4000 RPM and then held 27-28psi to redline. But my IS38 hit 28psi at 3100 RPM so the TPC20 spools about 700 RPM later.

did you dyno your is38 and tpc20 on the same dyno? I’m curious as to the difference in peak numbers

Yes same dyno and tuner. If you mean peak power numbers the IS38 was 362 HP and 408 torque and the TPC20 is 416 HP and 428 torque. Everything mod wise was identical when both were tuned.

Jim, I know the numbers say 700 RPM later, but is there a big difference in drivability? Especially compared to the IS38 you had? I would think so but sometimes graphs don't reflect reality.

No there isn't any difference in drivability. The 700 RPM later spool goes by in a blink. I should also mention that TPC is a great company to deal with. Very easy to get on the phone.

Did you post your dyno sheet? I wanna see!

They email back quickly, and plenty of info too

Yes I did but I don't remember what thread. I'll post it here.

Thanks. That’s a lot of extra power. Any idea if anyone ever dynoed an EQT on that dyno?

Nope no idea. I will be getting a remote dyno tune from EQT but not on that dyno.

Here it is being dynoed.

Glad to see another TPC20 user loving it. I've got ~20k miles on mine and still running great. Only pushing 27psi and very little timing, but it still makes for a killer streetcar. Hoping to throw fueling at it later this year and get a full e85 tune to see how usable it is with ethanol.

Measurement Mogul is a new one.

I measure things for a living.

Well I don’t race Go Karts so what gives. How you customize that?! I want a title too haha

My TPC20 is at 28psi by 3600 rpm. Seen this in all of my logs.
