ok guys i have a big problem. my boost gauge is flickering on high boost. its a defi d gauge. the boost controller is a profec b spec 2. i'm still learning how to use it. my setting are
set 63 gain 20 set gain 88. i tried gain at 5 10 15 and set gain at 0 50. still does the same thing. when it flickers up and down then straight to 24psi. i turned the mbc off and boost was steady, lo my settings are set 29 gain 20 set gain 96 and hold fine no jumping. i have the solenoid mounting sideways don't know if that matters. any help would be appreciated.

also i made 446whp and 330tq on 24 psi with 110 octane. the head is stock port with bc turbo cams, ferrera valves, crower valve train. this is on a sc44 turbo does that sound right. cause my car didn't make much more power as we were uping the boost. it was like it wasn't flowing or i maxed out the turbo. which it is rated at 545.

are you popping out of 4th gear or you cant find 4th gear? if its not going all the way into 4th gear thenyou probably have a bent shift fork. put that thing in 3rd gear on those burnout too. let some air out of those tires too, spinning alot in 2nd gear. what trans is in there gsr? what size slicks? Car sounds mean though man

that sc44 is probably close to maxed with the stock port LS. once you start getting higher in the boost levels the turbo will make less hp per psi of boost cause your gettign out of its effeciency range. Turbo's are rated at flywheel hp too not wheel hp so yeah your close to its max. You could probably run 30 psi but its not going to make much more power and will probably really bring iat up alot

thanks any idea with boost controller

[Turbo-LS]

I've never used a profec so im clueless on that one man sorry. From what your wrote your saying that its flutters and then spikes? or it hits the high boost you want and then flutters? check boost source and could be a bad solinoid

There's countless ppl on this topic are pushing way more whp then me on a bone stock LS motor.But is alway good to have insurance on this turbo sh!t.If u have a built bottom end, just bump it to 15psi, f*ck that go to 20psi!!!!!

it pops out it if i shift quick if i shift normal it doesn't pop out it feels like it barley goes in sometimes it does this in second when driving normal it will feel like it goes in but when you give it gas it pops out i gotta check and see if i used the shift fork that came with that tranny my ls i took off never did this oh the tranny is a b16 and the tires are m/t et st radials and they had 8 psi in them

[TURBODC4TEG]

with my ls tranny spinning the same i got 8.7 at 92 now with the b16 tranny the best i got was 8.6 at i think was 75mph i can't get 4th i tried twice power shifting it into 4th i got it one time out of the to but i shifted at 6k then i tried to hit 7.5 and i couldn't get it maybe its me im not sure i know my pedal has play so i got to adjust the pedal and see if that helps

[Eli2]

Hey just wondering if the B20 block is capable of handling the same amount of power on stock sleeves as a LS.

Do you have a short shifter in the car? If you do JUNK IT and put oem back in. If you have oem then sounds like bent shift forks or bent linkage.

No, the walls are thinner and will crack easier than b18 sleeves

[Eli2]

Exactly what I was thinking.

well I have stock sleeves and no block guard. There's countless ppl (i've seen) but yes its mostly for insurance. I dont want to go to college and have it pop on the way. I would rather enjoy it. Now during the drag season that's another story. Ill be bumping up the boost and tune on a diff. fuel. Idk what power mine will make...but it will be exciting for me. First B series, and first turbo. (<--that's why I prolly have that much "insurance" i the motor, cuz i dont know what they can handle).

comes with everything you need!!!!!!!

Went to another dyno day with the club and put down 283/295. Boost was hitting 21 psi at 4700 and tapering down to 17 by redline. The boost solenoid is almost at 100% duty cycle so the exhaust manifold is keeping it from flowing more. Im pretty happy with the #'s though. Im looking at a miniram so I can finally ditch this greddy manifold.

Blues are old, greens are new.



Oh and my roomate, who has a built LS turbo, sc61, made 502 whp on PUMP GAS with a STOCK head (IE no head work) with 404 cams. That has to be record for something.

The dyno had no rear hook for FWD cars so we had to have 2 diesel trucks back up and hold both his car and mine hehe.
