turbo/wastegate

[dipapadakis]

pulled off my turbo because i was only getting 40lbsof boost and it wasnt pulling hard or spooling very fast then saw it was cracked and wastegate is basically always slightly open and many small cracks travel the inside would this cause that big of a driveability effect and corelate to slow 1/4 time 14.5 was best ive ran

Yes if your wastegate is stuck open even a small amount your boost level and 1/4 mile times will suffer big time. Is that a stainless HTT exhaust housing? It looks like it is because its the only two puck wastegated housing I know of, which if it is they are known for heat and exhaust pressure bending the wastgate arm after time.

Pretty sure most of the s300's have the 2 puck design. Dual 5/8" IIRC.
