Question GT4088 on stock ports

Anyone have experience of this?

I was looking for a Gt35 but one of these has come up at a good price. I intend to go for a large street port at a later date.

Purpose is for a street/track car.

I had a small street port and got 15 lbs by 4300 RPMs on a 4088R with a 1.19 hotside. While the BB might help with spool (maybe 200 RPMs or so), a smaller hot side would give a similar response for a journal bearing 4088R. Made 430 rwhp at 15 psi.

Appreciate the reply buddy. This is exactly the sort of info I was after.

Looking at options at present. TD61 followed by gt35 are still favorites but so much to consider.
