Next Steps: Lowering EGTs?

[crf250guy]

So I just recently completed installing an adrenaline hpop, stage I injectors, and a big head wastegate actuator. First of all I have to say that I am amazed how much the extra boost helps lower egts even with all the extra fuel I am delivering. That being said, I am still climbing into the red in the 80hp and 120hp tunes. I dialed up my stock turbo from 25lbs to 30lbs (in the race tune) and noticed an improvement, but I don't think its going to hang in very long at that load. What would you guys recommend? Bigger turbo or backing it down to 25lbs and doing other mods?

Also, can the early '99 turbo handle more boost than the later year models? I was surprised how noticably the EGTs dropped when I steped it up to 30psi.

time for a new turbo...! not sure what you want with the e99 though.. hmm

And what do you mean by red zone?

[crf250guy]

I meant that it starts heading over 1250 deg, but I didn't give it a chance to stabilize. I would like to be able to hold it wide open in the 80hp tune without exceeding that. Seems pretty possible given how much more fuel people put to these

Turbo time...

Being you have a early 99, A D66 or a H2e is your best bet.

Do you guys think that with a D66 I can keep the egts below 1250?

more are balances out more fuel.

So to throw another kink in this... I just found the Early/Late Conversion Kit at Riff Raff and I have an up-pipe leak. I'm currently looking at two option: 1. D66, new oem up-pipes, and beans brass donuts, or 2. Conversion kit + 38R. The second is obviously more expensive and I don't know if there would be any benefit. Any thoughts...

I would say it depends on your future plans for the truck. If you are staying with stock injectors, PROBABLY not worth it to go with the GT38R. It is a great turbo, but there are cheaper ways of accomplishing the same thing for stock sticks. If you plan on upgrading injectors then the GT38R or modded H2E become worth it more and more.

He's got stage 1's...

Proly aught to upgrade the turbo and get the leaky up-pipes fixed (I assume) That'll help your egts
