Well finally took my beast out to the track. Mods are in sig but its a full weight ccsb 4x4. Small drop and bolt ons. Ran the truck at firebird raceway in boise Idaho at 2700ft altitude. Air is bad up here but truck still ran good on 91 tune. Came out of hole decent but when I hit 3rd gear the truck felt like it hit a wall. Went from pulling hard to dragging it was really weird. I wonder if the 3.73 gears are whats hurting me or something in the tune? Let me know your thoughts. So far Im happy for only 373whp. Will have my tbss manifold, 90mm tb and injectors on hopefully by next race on the 27th. Really want to make 400whp and run 13.5@100. Im sure the injectors alone will get me there. its literally pegged for fuel with current setup LOL

Left slip is vs my buddies 08 jeep srt8 with diable 93 tune, 4inch intake and muffler delete. Shows how bad the air is here. That jeep would run 12s at sealevel track. Im racer 311 if you couldn't tell.

 

nice!!

 

Nice consistent times!

What fuel pump do you have? Sounds just like my truck when the stock pump started going weak. Would pull great through second and then fall off in third.

 

stock pump and injectors. LOL I have injectors for it to go in but I should probably get a walbro for it also. I bet it has 13.5s easy with just some more fuel.

 

Injector wise you should be ok. But to me it sounds like the pump isn't keeping up. Best thing to look at would be IDC and fuel PSI.

 

The stock pump will handle all the Stock injectors can and then some.

Do you have a converter? Great times!! You're not far off that jeep at all.

 

Those are some damn good times!

 

I have a trailblazer i5 conv. It stalls to about 2600-2800. For me that's just fine. Not a drag truck and I like my mileage LOL

Got those 36lb injectors just need to drop them in. My injectors are big time maxed. Hp falls flat at 5000rpms to 6500 at 370whp on the dyno. Im certain this setup has more power in it with just more fuel. I just need to drop those in and my tbss intake manifold and hit 400whp

 

Wow great times for those mods! I have similar mods and ran similar times in better weather. My tune wasnt spot on, but everyone has their excuses...

 

good times considering the elevation!!
