peter, yes i can build boost to 8lbs right after it warms up a little and then just leave off the brake, i must hold the pedal down so hard to get the truck to not move but there is no wheelspin at all. its amazing really that it wont spin a lick, i can get in the ty and the 18s do nothing but spin on anything over 3lbs.last time i went to the track i had the stock wheels and tires and i did a 8lb launch thinking the track isgoing to hook so much better, well i almost hit the tree the truck spun so bad and pulled to the left but i did not want to let out if it so i kept going and only pulled a 1.89 short time and the intercooler hose came off at half track and still went 12.40 at 99mph, and that was before i did the bigger turbo , speedpro , bigger cam, weld wheels and tires, no ac now. Anyway , the build i think is identical to yours, mccoy supermotor , 72 turbo from mike, speedpro with 72lb injectors, not sure off cam specs, jerry mccoy said he uses this cam in alot of these builds, 1.5 roller rockers, 52mm throttle body, dequick intercooler, fluid damper, hartman stage 5 tranny and his converter which i can not believe the difference that this tranny is like now. night and day difference, it is so much fun to drive now,what elsedo i have umm, no ac, no heat, no windshield resovoir, no abs, battery in bed, alum. driveshaft, atrs front propshaft, rearend girdle, number 8 fuel line, 2 fuel pumps, msd. the weld wheels were 180.00 each , 16x8rears and 16x8.5 fronts because you can get 5.5 backspacing with that size and i went with 4 inch backspacing for the rear, it looks really tough. the et streets are 26x10.50 Like i said i can not believe how good it hooks up on the street , no spin at all, i am only running 15lbs of boost so what boost and fuel do you think i need to get that 10.90 pass and thanks for sending rob the program. jack ostrander
Hey Jack,
good to hear from ya. you DEFINITELY got a 10 sec potential in your Sy if its same build as mine....:smile:....Anyway, before I forget, lemme ask you 7 more Q's than I'll answer yours:
1. are your Welds a "street" rim or drag only rim? which Welds are they?
2. what do the front/rear Welds weight individually and what do the ET streets weigh?
3. why did you got 16x8? I woulda thought you'd gone 17" for looks or 15" for weight reduction/tire selection
4. finally, I saw ET streets come in 11.50" width too, so why you go 10.50"? 11.50 won't fit under Sy? rim too narrow? I'm askin b/c I want order 11.50's if they'll work
5. How does sy FEEL w/this setup at higher speeds, turning, braking, handling in general? Again, I'm askin b/c I drive my Sy on street 90 % time and wannma know the trade offs of goin this setup.
6. You ever dyno Sy? who tuned it? is tunin it?
7. you weigh Sy? what it weigh w/you in it and by itself?
Now, your Q's (finally right!!!..LOL):
Heres my experience.....you'll need minimum of 20 #'s if your Sy COMPLETELY dialed in. I needed 22 #'s b/c rich, low timing, AFR conservative. After reviewin my log of run and BG's help, I'm FULLY convinced I could do it again on 20 #'s.
I also have EXACT same prob you did w/hook. I thought E-town track be BEST (right Mike l? j/k) for hook b/c VHT, its track, etc....You should see how wrong I was. I would stage and pull HARD like you towards stands, tree, etc....scary shit...Plus, if I left soft so tires wouldn't spin, I'd bog and get bad 60ft, if I left more boost, killed tires, and bad 60 ft..this was on ALL BFG DR's too...only thing that helped was heatin tires and thats ROUGH on drivetrain tranny..
I've been talkin Dean, BG, others w/fast sy/ty..and I'm convinced we need what U have now..slicks in rear and BFG DR up front....I'm VERY encouraged by your results so far and I can't wait for U make passes. I KNOW we can go .5 60ft if we can leave w/more boost..hell, DSM's guys run 1.4 60fts all day when setup properly...we need work on our suspensions too..Where are ya Mr. Dustan...:smile:
Have you played w/TCC lock up pt too? I may try lockin mine like Dig, ML, Kris, others on 1-2 shift..I tried it this year and OH BABY, Sy responded..big PUSH in 2nd
Hey, gimme your exp w/Hartmans tranny/TCC setup too as I'm buildin tranny now (not as good as yours), but I'm really curious see how it holds up to power were makin...
I'd say shoot for 1.600 60ft, hold on, and enjoy ride to 10's
Please keep log of everything so we can compare notes..boost, launch boost, etc...
You put T Brake in your tranny too? if so, gonna use it?
My goal this year is keep tunin the sucker as I got WAY more in my Sy...bout 7 more #'s boost, timing, etc...I think I can run 10.50 to 10.50 stock block/crank if I sneak up on it...
Lemme know if I can help in anyway
