not trying to steal the thread but are there any upgrades for an ht3b?
Yes, there is! I got one from Piers' a few years back......kinda stole it from his stash :thankyou2: called it a 3b.5 much larger comp side same ex. I ran a 26 then found a 22 for it and that improved the spool-up alot but would get hotter on top.
It would get to 1000* really fast then slow from there ran it a few times at high 600's (692.5 high point) on a Mustang and could keep egts to 1400* just wasn't real DD friendly and we recently bought a 5th wheel so I went to a 4202/small 400 for better spool-up!
It's sitting in a box while I decide if I'm gonna use it on the wifes truck or not!
