U still on oem head bolts? factory TTA spec?
Its a KRC Power Steering pulley, 3.5" diameter. With the stock pulley my voltage would drop to low 12s over 6900. No issues charging at idle. Engine warmed up, fans on, both fuel pumps and lights on it will still hold 13V. I put ARP head bolts on this one.

Thanks! Yes, I am still using the twin turbo cam in this 5.3, I still have my 4.8 in the garage for back up. Going back out to the track this weekend, hoping to see an 8.6x @ 160.

Too much has changed for me to really compare the two. The twin set up was in a low compression, iron block 4.8. New set up is an aluminum 5.3 and I've got the dome control now, which I didn't have last year. On the street the new set up is definitely more responsive, but its got a bigger motor, car is lighter etc. One of the main reasons I did the single was to be able to run a full exhaust easier.

Understood. Full exhaust is awesome. Iím sure itís holding me back a little, but it sounds tame and isnít obnoxious drivin around.

Went to the track for the final time this year. Was a pretty good day. Got an 1/8 and 1/4 ET best and a 1/8 mph best. The track surface was is really rough after the 1/8th mile, which caused my car to bounce around a lot and tag the limiter a few times. Which is why the 1/4 mph was down a bit.

do you have any photos of your exhaust system?
I am going a VS single 80mm turbo in a fox body and want to do full exhaust at well...

If you scroll back thru some of the old pics there are a few shots of it. The downpipe dumps on the passenger side through an electric cutout. There there is a 2.25" T off the downpipe that goes out to the rear axle with a muffler.
