I normally try and exhaust all options before posting on here , but this has me stumped.
ill lay out my set up first and explain my issue second.
-63/68/12 gated over a box s480.
- spring gate from stainless diesel
-ddp stage 4 injectors
- timing at 22*
- pump is a 215 bought off a comp member that shipped it directly to kevin for me . its maxed and balanced flows 650cc plate full forward , 300cc full back. with 024 dvs and 4ks . I've had the pump about 3yrs now. it has a gov spring in the afc from seth set at 40 psi full fuel , using regulated shop air.
-supply is an airdog I forget what with a torktek 60 ofv
- cam is stock
-bottom end stock
- heads been oringed with 425's
no fuel press gauge , no drive press gauge
I've never been past 3/4 throttle with the truck and this 913 (only when it was a single 62 and that was pointless) , its always been to much.
rolling into it in 3rd, it'll light . ill see 60psi total 30 psi primary ...touch more throttle ..70 / 35 ...80 / 35 .... 90 / 35-40 .... 100psi i'm around 3/4 throttle and let out ... i'm not sure how far it'll go i'm not brave enough or rich enough to try It . when lit it clears the smoke very well.
I need to strap all the I/C piping together because I blow them apart. all bead rolled all tbolt clamped blows the boot right out of the bite .
the plate is back to a little less than half travel , housing too , zero preboost . throttle is very sensitive .
a good friend is running a 62 over 475 , ddp4+ , manning cam, and a maxxed 180 pump ,plate forward at 500cc , westons 7mm dv's. it'll hold 70 psi full throttle with 30psi primary . hardly any smoke . springs are 4ks and the throttle is way less touchy .
I let him drive my truck today and he had a hard time mines so touchy.
i want to think my ratio is pretty good , my cruise egt is 6-700 .. im sure i could benefit from some tuning but it drives pretty well and spools quick imo.
it has power .
i just don't hear or read of many people building that much boost with this size compounds . any thoughts or similar circumstances ?
