Paxton TPI

Anyone runnuing a Paxton S/C?

I am looking at a 88 Formula 305 TPI/auto with a paxton.

Are they reliable, good brand? Any issues or things to watch out for?

Please go into detail---I know very little about them.

thanks!

86 iroc tpi 5.0 w/paxton sn series huffer installed.
with a bone stock engine this mod rocks! it is the perfect match to this intake set up. stock t-body/runners/base/cylinder heads all have small ports and many restrictions, combine this with a small cylinder bore and high compression ratio and you see the boost rating of 5-7 psi jump up to 9-9.5 psi. acceleration and top end are very good. doing a "street start" in a blown tpi f-body is breathtaking.
