Second Tex275 class

[BoostedGT]

Precision dont make this turbo anymore 98/88

rules should be

76mm,80mm,or 88mm at a certain weight and that is it. no billet wheels

Thanks JMO John Sheffield

Precision said if the interest is there, they will do a small production run for an 88/98mm turbo...

[BoostedGT]

I'd recommend a 50lb increase on the 88/98... I see that combination getting out of hand pretty fast. Also, 50lb reduction for the gt47. You have 100lbs separating the two turbos and there is a night and day difference between the two. Also, allow the Ultra Street 80mm turbo. Those are running right around the ET range you're looking for... But the Ultra street turbos are based off a GT-55 so I think you got that covered in the 80mm rule. Just my two cents.

^ agree. Keep rules close to ultra. Guys are dipping into the 4s already with the 80mm.

Just talked to Grant Precision Turbo and they don't make the 98/88 and won't build me one out of my 106.
Guys if y'all don't think John Sheffield is run 4.80s or better on a 40 pill your crazzzy
Just my 2 cents

Maybe you missed my post... Precision will do a limited build of the 88/98's if the interest is there. Don't believe me? Call Precision, ask for Justin. Talk to him.

I got 1 but if a turbo car is fast in that class it will only get to run 1 time. John has head hunter heads derrick said those heads are not legal for the class.

Derrick said no raised runner. X275 rules say no raised runner head hunter heads.

That's great I thought all head hunters were

I just hope my old turbo keeps up

Should be fun.

[jason07]

Also, allow the Ultra Street 80mm turbo. .

What is an Ultra Street turbo? Precision? Borg Warner?

I thought it was an 80mm period?

Your turbo isn't legal for the limited class.
