Doesnt seem right. 31lbs to hit 1100rwhp and back pressure that high. Not sure what's up but 370ci. And a 235 head should do better. Something is to small or your cam is off. Figure out the back pressure issue before you get a bigger tirbo.

Had a great day at the track today. It was my first pass since I did a big wheelie at Maple Grove about 2 years ago in the end of October 2018. After that wheelie I have made alot of changes. It started with changing some suspension things to stop the wheelie. All 4 shocks revalved different torque arm and lower control arms. Just after that was done there was a opening at the fab shop so it was time to upgrade the cage from a 10 point to a 25.3 with that mini tubes were done and other odds and ends. The car ended up being 100 pounds lighter with a new race weight of 3600 lbs. I also decided to make the switch from a stock computer to a holley computer. It wasn't a easy switch had the car on and off the dyno like 4 times but got it all figured out but ran out of time by the end of 2019 to make a pass. As for the start of 2020 the race season didn't really get started till it was hot out so I waited for cooler weather witch is now. The day started out great with getting my personal best pumpgas pass off the trailer witch was a time I figured I would never beat. After a couple more passes being consistent made the switch to c16 and turned up the boost new personal best on race gas and no wheelie. Just out of fuel pump so thats the next upgrade.
