Building boost at the line

[GBGN1]

I have a 3200 stall with a te -61 and was told i should be able to build 6 or so lbs boost at the line..and cant build no boost..Does everyone "load the convertor or just let idle and mash the gas.I loaded "raised the rpm at the line only to about 2200 and the tires start spinning.
any help would be great

Its not a 3200 stall then. If it stalled at 3200 at 0psi then it would be a 3200. You really need larger wheelcylinders and or an adjustable proportioning valve to be able to hold high boost (10+psi) launches consistently. Back in the day i used the e-brake and the foot brake for extra holding power . I was lucky to not rip my backing plates. Others havent been so lucky using the e-brake. A trans brake is always nice too :biggrin: . You cant have any exhaust leaks before the turbo and the wastegate must be 100% closed or it will spool like $hit. The exhaust restriction after the turbo will slow down spool rate also. I typically leave at 10-12psi myself, but i have a 70GTQ and hope to get it dialed in at 15+psi on launch for some low 1.40 60's

I sort of disagree with your first statement, because if it were an all or nothing affair, everystoplight would be a 3200 RPM launch before the car got moving.

Having said that, I'd like to know too, as I cannot build any boost whatsoever without the car rolling through the minimal braking power the powermaster gives.

One thing to add, the chip is a major factor in building boost. My TTA was somewhat sluggish building boost at the line and in general. I swapped over to my Max Effort chip from my GN and there was a major difference. I

have a 3500 stall with a 63E turbo and the car makes boost on the line with ease. I would look into exhaust leaks before the turbo or fuel pressure, or chip.

Too much fuel down low = no boost

You have to throw max torque at it to get the stall speed. Which means you hit WOT without the car moving to get the stall speed. This is not something you would do at every stoplight. 3200 at 0psi and zero vacuum is 3200.

I do need to put those s-10 rear brake cylinders in--thats a given.I was at the track on sat and ran a 13.03 at 105 (19-20 psi)with a 60 of 2.055 which sucks.I need to leave with boost.

Specifically which S-10 cylinders are used?

I need that upgrade too, anything over 2 psi becomes a burnout.

Thanks

85 S10 wheels cylinders for manual brakes work. they are 7/8" i believe
