20 psi on modded stock turbo with mods. Possible?
My friend told me his cousin my modified the stock turbo to run 20 psi on his 87 t2. Is this possible?
He claims he saw it push this much boost. The car was a half bridge running 3" exhaust.
Not sure of other mods but was told the car was close to 400whp and capable of running 11's

Yes. I've put my stock turbo through 20+ psi accidentally. It's not a smart move, but it is possible. After about 12 psi on the stock HT18, you're no longer in the efficiency range for that turbo. So all you're doing is pumping a lot of heat at a higher pressure. That will raise the intake temperatures to a dangerous level. You won't make any decent power at that point though, and you're risking severe detonation from the higher intake temperature. It's just not worth it.
I have my T04B hybrid turbo turned up to 15 psi, and that's as high as I'm comfortable with.
Are you referring to a hybrid turbo when you mean "modified stock"?

I'm not sure, my friend said he saw his cousin's stock Turbo pushing 20+ psi.
It had to be clipped and modified in some way, possibly a hybrid.
All I know is from the stories I heard the car blew 3 foot flames and could spin 3rd gear.
Obviously must of been running rich, but it had to have a lot of power.
The car was sold to another friend of mine after it was modified , that friend died of cancer, now his younger brother has it as it was passed down to him and its been sitting in a garage in memory of his loss for 10+ years.
I keep telling him to work on it, but he never does.

I've hit 17 before, but that was because my wastegate lacked flow and I coulda popped the motor quick. I did the shaving mod, smoothed the boost out a whole lot to a steady 7-9psi, but for pushing more than 12 out of the stock turbo, it's just risking your motor severely. Get a turbo setup if you want more power, let the ht18 stay stock.
I'll be posting a turbo upgrade soon with a t4 gt35r on my fc.

300whp isn't attainable on a completely stock turbo, no matter what psi it's pushing.
Spinning shitty tires in 3rd is easy with less than 300whp, and N/A rx-7s with 130whp can shoot 4 foot flames. Seems like you can't tell when someone is blowing smoke up your ***.
Are there any dyno plots or time slips from the car? If not you have no reason to believe it was any faster than a stock RX-7.

Well, a BNR with a sanded exhaust housing do look exactly like a stock turbo. Or with the black exhaust housing it looks like a stock turbo that has been painted. Badum-tish
