Ill probably just put duct tape or something over the hole, or just leave it open for an engine bay vent

Ok so I went out and installed a bigger wastegate spring that allows me to build more than a 7psi launch...lucky I was 1/4mile from the house because I had to drive home in 4hi. Apparently I will need traction bars to launch on 13psi, because the rear springs wrapped and busted the rear universal joint. Luckily it barely smacked the gas tank and sheared 2 caps off the joint, the ds survived. Time for cal-tracs or Smith Racecraft! LOL!!

I had 14 psi just off idle at the launch. When it unloaded the front end, "violent" is a good verb.... It also turned hard left, which will scare the **** out of you pretty quick, and the pucker factor gets pretty high.

The track manager(in my case track owner) was not impressed or happy about it.

With straps & CalTracs, and drag radials, I could still have some tire spin on the launch, but it became manageable.

Before I strapped the front it would buck a little and pull hard left. The straps fixed that problem but my truck was lazy to build boost with the 5lb spring in the gate. With the 9lb spring the boost comes on violently and this morning was the first time I have tried to launch over 8psi. I think I'm gonna go with the Assassin bars and some adjustable rear shocks

Bringing this back up...I got my bars put on and adjusted. Now I spin for about 20 foot and it finally hooks(street tires) LOL!! Now I need a $1200 set of drag radials. Does everyone recommend the M&H 275/50/17's ??

I prefer the MT ET street radials over the M&H (which tend to run small)

Those would be about 400 bucks cheaper but I would have to step down to 16's. Who has ran 4 of these on the street?

I used to use that size m&h, they worked pretty good! Very soft though, maybe 10k street miles tops.
