    Verifying of 3bar MAP, boost gauge, alky.

    While waiting for my TC to get here I got this hair-brained idea to check if everything which is reading manifold pressure is reading correctly. No pics but they wouldn't help anyway. Here's my setup. FIRST turn the alky system off! Safety first. Using my cyl leak-down tester from Harbor...

    Admin, My email account was hacked on this end. Got a note from my ISP this AM. Passwords have been changed on my end. LMK if you'd like me to change my syty.net password. Did you see any strange activity? Don

    Yuk

    :tdown:Apparently I F*&^%@ the rear main seal when assembling the motor. It's leaking like a sieve. Hope to pull the motor tomorrow, Wed at the latest. Back together by the weekend. But don't bet on it. :rotf: It's possible to change the seal itself I know but if it's not just the seal then...

    Radio on/off switch FIXED

    My on/off sw has failed. That is, it sorta works if held in half way. So... A) Can it be fixed? IE remove radio, access switch and spray contact cleaner in it. (Didn't work just trying spray from outside.) Or B) Is there a replacement that will fit? Including a CD player? From what I've read...

    HP question

    I've done some of the online calcs for HP based on ET/speed and I come with quite a bit more than 500 HP, IE in the 530 range. Wt of my truck at the last trip to the dump was 4500, seems a tad high. Best ET last trip to the track was 11.85, speed 116 I'm frankly amazed that I could be making...

    Slow

    SyTy.net seems very slow to load last couple of days. Browser says: "waiting for stty.net." Could be me but other pages seem to load fine. I've cleared cache but gone no further, no help. Just FYI. You guys do a heck of job, I appreciate it. Thanks!

    ARP studs & nuts

    I have 16 short 4.262 long, and 1 long 4.482 ARP studs with nuts and washers. They have been used once. Right this minute I can't tell you if the rear main takes a longer stud or not. I didn't think so, so where the long one came from I can't tell you. Anyway, I'll split into sets. How about $50...

    RPM 50# AND 60# chip

    I've gone to a different setup so here's the deal. The 50# chip is NOT patched to log your wide band. The 60# chis IS. there are 16 "tunes" on each of these chips. 10 for without meth and 6 with meth. What they do change the timing and the mixture. There is a Motes remote control for the board...

    Old Clifford alarm

    I have an old clifford alarm for sale. Complete as best as I can tell. It was removed from my truck a couple of years ago. Comes with a wiring diag. The model is Cliff Alert III (3) I'm thinking $60.00 shipped in the USA. If that doesn't fly then make an offer. Thanks

    11 second day

    Well sort of. First run 11.951 Followed by 12.144, 12.016, and 12.094. I'm a happy camper. Truck feels strong. Not going for any records but it's fun running this quick. 20# boost, pump gas, alky turned on. Virtually -0- spark retard.

    Some good runs

    New best actually. After some initial missteps the truck put down 4-5 runs all at 112-115 and more important, all in the low 12.30's very consistent. Makes this bracket racer happy. All on 91 octane, 20# boost and no meth. Probably an 11 in the future but the season is ending so may have to...

    Dipstick part number

    Does anyone have a part # for an aftermarket flexible dipstick replacement? Or the entire tube and dipstick. Regular flat stick only bends one way and I need one that bends both ways. Tons of sticks out there for transmissions. I didn't see any long enough for our motors. Thanks

    Build finally begins IT RUNS!

    Some differences in my block. There is no step for the 2 center 4 bolt mains. Also the outer bolts do NOT go into the water jacket. Caps are flat. The cylinders are relieved. Crank in and torqued. If I stop it in the right spot it will go back a little bit by itself. That's how true...

    Vote on a cam

    Crunch time on picking a cam & lifters. Given similar grinds what BRAND are folks most happy with. Drag raced Streetable truck hybred turbo, 2800 stall, 60# injs, built trans, probably forgot something.:lol: Choices (at least at this time) Nolan Comp Crain Lunati Crower maybe Isky Other...

    Different intake port mod

    Done some searching, came up empty. Lot of folks have done that little "porting" job on the upper intake to better match the lower. This idea is different. I want to improve the performance of the stock SyTy intake, upper and lower. ( among other things no money for a fancy-dancy alum set.) So...
