I usually get about 19ish with a 50/50 mix of city highway and my own heavy footed escapades. Thats with a lex afm, 550's (that's in question right now though), and full 3 inch exhaust with no cats.

Guess what.....I got the head off today and found a melted #1 cylinder......and i have suprasport pte injectors with no flow sheet drop shipped from another performance shop in Rhode Island. I'm going to ohm them out then send them off for flow matching before i put my backup motor in...

Thank you sir, I won't be able to call SS till Wed now and this will help a lot. Puts my mind at ease. I actually don't mind it staying stable at 7...i have a boost controller....I just want to make sure it ain't broke. Of course since it holds 7-8 psi dead stable, I didn't think it was faulty...

Yeah, i had gotten the oem disk from autozone and put it under an RPS blue plate. so far so good, boss 550 525 hp model @ 18 psi no slippage ;)....#1 cylinder died though so when i have the motor out again i'll check the disk and see if i need to cash in the lifetime warranty :D

i ate up a spec stage 3 with 325-350whp in about 6000 miles. needed a new flywheel too. the 6 puck had grooved the flywheel and the pressure plate about 1/8 inch deep and about an inch wide. went back with an RPS blue plate special and an autozone lifetime warranty disk *wink wink* and i have...

Interesting thing, I bought a lipp afm/pte 550 combo from Suprasport a little over 2 yrs ago and low and behold I got a package drop shipped from darkside racing (or something like that)with no flow sheet and 1 o-ring. I think i talked to Jeff (it was march/april 2005) and he said he'd contact...

I've been working during their business hours the last few weeks and I haven't been able to do anything but leave emails that have gone unanswered. I hate email cause it often gets lost and redirected. I just thought I'd ask and see if anyone knew before I called them this week when I'll be...

I had gotten in a boss 550 turbo and i was wondering if anyone knew the wastegate pressure on it. When i first put it on it would boost to about 1 bar and then after a few days it moved down to about half that to about .5 bar or so. Now it is very consistent and it holds that pressure. I just...

On the profec b spec II if you turn your gain (waste gate duty cycle) up too high it makes the electronic solenoid open and close faster and more often, sometimes the noise is audible over the engine and it sounds like a card flapping on bicycle spokes. Mine did that for quite awhile till my...

First off, you will be harassed by the loving old schoolers here for not using the search feature to check on these very well covered topics. Most of this is readily available info. Intercooler piping, 2.5 is fine for everything you will throw at it with a stock car....same for the spearco...

Since the factory throttle in a MK3 turbo supra has a cable attached to a swivel, attached to a rod that turns the device attached to the trottle plate to open it, there are 3 swiveling points at which the direction of the motion changes, all of these add slack to the system. The average honda...

pull the accordian hose and pull back and forth on the front of the compressor shaft, if it moves in the front to rear direction (mine was 1/8th of an inch) at all it is likely to be going bad. best to pull it while you can still possibly rebuild it. mine smoked when i let off and coasted then...

As frightening a thought as this sounds, I looked into converting a spare stock turbo mani into a FFIM and I found that not only was aluminum hella expensive to weld, but many alloys can't be welded, only cast or machined. With that in mind many places use a composite process by which an epoxy...

Just to address the final verdict......TSRM specification for axial shaft play is something like 0.00051 inch......my axial shaft play 0.1250 inches........Turbo 62-1 is dead as a doornail. At its funeral the eulogy will be given by its succesor once chosen. It will likely be a BOSS 550 54 trim...

damn, then I may have to rethink my options. Although since the car is already down I may go with whats readily available. Anybody got personal experience with the lightning to give perspective.....Malloy and 67mm of BOSS turbine is not a good reference point for what I want....well what I...
