What did I miss? Why are all the avatars round now?

Consider it practically new. Mocked up on project motor, run on a stand, but no miles. Matching doghouse is already sold, so just the TB and a gasket. $199 + UPS Ground from 98226 + 3% if PayPal.

I could use a little advice on wiring up a cut-off switch in conjunction with Casper's "volt booster" for the fuel pump. I got tech'd out at the track last Friday as my cut-off switch didn't shut the car off (first time in 8 years they checked it). It certainly wouldn't start again, but the...

Mission Raceway in B. C. stopped selling race gas. Anybody know where I can pick up C16 north of Arlington? I live in Bellingham so Mission is close for some fun, but my setup requires C16 or it's head gasket time. I usually just buy 7 to 10 gals at a time that I put in fuel jugs, so I don't...

I am looking for advice on external wastegates to avoid boost spikes. My combo is in my sig below and my specific issue is a 4-5lb boost spike since installing the FMIC and having to rewhack the actuator mounting to clear the reclocked turbo outlet and the external wastegate port on the turbine...

Need a spare for an experiment. Mild steel is fine. Thanks!

I'm almost complete with the install of a roll bar, which will have side bars on both sides with swing outs. My question is does anyone have any pics of a properly installed side bar that allows clearance to open the door handle? If I stick to the rule of the bar passing my arm midway between...

I'm putting in a roll bar (6-pt) and am wondering why so much discussion on the Cr-Mo weight savings. I tried a quick calc assuming 40' of material (1-3/4" O.D.). Using DOM steel tube of .125" thick and Cr-Mo at .083" the difference in 40' of material is 28lbs. A 3650lb car needs about 550 RWHP...

Last season, I ran a trans brake and finally got the car tuned decent enough to run a very high 10. This winter I'm adding some safety gear (roll bar, trans blanket, C-clip eliminators) to stay legal. While I'm at it, I want to increase the shift rpm at the 1-2 shift. The trans is shifting...

I have Razor's kit. When trying to prime the pump after it's been sitting awhile, the pump won't run when pressing the test button. The red LED comes on, but the engine won't stumble at all. Disconnected hose doesn't show anything coming out either during a test. But, the pump runs full bore...

Okay, so I finally broke into the 10's with some jolly 60' times and really need a roll bar. I want Cr-Mo pipe and done nicely (not through speaker holes, but next to them) with a swing-out driver's bar. Does anybody have a name of a good contact for this work? I can trailer the car and will...

Anybody dealt with Weld Pro Stars and needing longer front wheel studs? Track Tech is getting real picky and wants me to change out the front studs for the thicker Weld wheels. Just need to know the knurl diameter for pressed in studs. Probably stick with 12mm so I can re-use my chrome acorn...

Stock GN Posi carrier (w/o gears) only 34,000 miles on it. Removed from rear end intact; not taken apart, so it's ready to install as is - $150 (not inc. shipping).

Apart from the obvious of having too little fuel, I'm getting a strange occurance of the low fuel light coming on for a split second on hard launches. I know I had 8 gals of fuel in the tank since I personally filled it with 10gals of C16 earlier on race day. I only made a few runs before it...

I need an opinion on the attached dyno graph and the performance of the PTC 9.5” converter I’m using. The graph compares one of last years dyno runs using a West Coast Converters 2800 stall L/U (locked up) with my current PTC 9.5” 3000 non-L/U. The top light blue line represents last year’s...

Wondering if anyone else has this problem and how to fix. When I have PL monitoring and use the line lock, PL just freezes up. Sometimes I can simply switch from monitor to review mode and back, but most of the time I have to shut down PL and restart it. That's a bit of a hassle to do right...

West Coast Converters, 10” 2800 stall L/U - $200 ($450 new) – maybe 50 miles on it at most. Stock GN Posi carrier (w/o gears) only 34,000 miles on it - $150 Stock GN axles (2) only 34,000 miles on them - $75 Pair stock GN exhaust manifolds (driver’s side is actually ATR stainless...

I have (2) 275/50-15 555R's Drag Radials, BRAND NEW. The red tread stripe is still fully intact. The tire store wants too much in restocking fees that makes them available to you instead. Why give them the money? They have never been driven on. Only the stickers have been removed. $220...

Looking for help from Julio or other. My pump suddenly stopped pumping. It was working perfectly and now when I press the test button, I hear a high pitched noise at the pump, but nothing comes out. The red indicator LED comes on when I hit the test button, just like always. I first noticed...

In trying to put the heavy spring in the 2nd accumulator housing, I apparently cracked the piston and it gouged the housing. No one near me has one for the GN. Does any trans shop reading here have part number 8657753? If so, let me know by PM or here. Thanks!
