PT70 GTQ sweet spot

[Not Avg 6]

What do you guys think is the best power range in boost for a PT70 GTQ on a mildly ported aluminum headed 109?

Thanks

25-30 psi

What cam? On a 231 ci engine with a large hydraulic or small solid roller around 26 psi. It would make power to 32 psi.

Perfect boost level ...

I would say around 10-12 #s when racing any White T. U know the white cars dont go that fast so I think Im gonna need a spot! Hey, Mike the word on the street is that U washed ur car but didn't wax it last weekend! Ur startin to slip brother!

currently just bought a 70 gtq and its goin in a hybrid 89 notchback, would have rather gotten a DBB but got a good deal. with my car being a lot lighter then a usual gn ot t-type spooling should be a prob? just wondering what some people think about this turbo and how its worked for others?

Thanks, guys for your advice.

Brer Rabbit, I better get back on my game. Washing and waxing is the only thing I can try to bet you guys on.

I didn't think the boost could go lower than 34-40 psi?? lol

More than likely the truth on a lot of TSM cars . LOL!
