Ram From Hell said:You just realized one of the cool things about turbos. Elevation changes don't effect the efficiency of the air compression much at all.

It runs just as good as it looks....I would like to thank you justin and all his guys at jmb.....and thank you to joe at pbj!! You guys are top of the line and there is no one elses hands i would rather have work on my truck!!! This is the beginning of great things to come for a lot of other board members i am sure!!!

Thank you for all the compliments but it wasnt me it was justin!!:elefant: :elefant:
Stupid fast doesnt even begin to describe this truck.............no disrespect to any board members but i have put more miles on this truck in the last 3 days than some trucks have in the last year!! :burnout:
Dave T(BADVENM) said:What about the tune? I had to tweak my tune from saint louis which is near sea level to western kansas which is 3500 feet. Denver is even higher. Does the tune need adjusting as well with large elevation differences? For some reason I should know this and would say yes but I thought I'd ask. I'm wondering how the a/f numbers on 505's ride will be different given his elevation now vs where the truck was tuned.
No Dig said:thank ya sir,
I've worked with justin for a while now and had a ball working on this truck between a 45 hour a week job and being in school.
I can vouch for his work, all the work on this truck is so perfect, that pictures can't show the details.

no need for tuning changes, the turbos are super efficent:rock:

and he has a single one and is running 1079 or so?

Stinker said:basically because my tune is super super safe, its actually rich as hell, plus I personally dont like relying on Meth or other additives like CO2 to make the power.
Justin did a helluva job:rock: and yes a single takes more time to spool than a twin.
JMB Justin said:You guys are dead wrong on the spool time, I guarantee that truck spools as fast or faster than Tony's twin 61's. Think about it 250 ci per turbo or 500ci per turbo, half the cubes spinning smaller turbos vs. all the motor feeding one big turbo. Like I posted earlier, a twin 67 viper on the same dyno took 800 RPM longer to spool, and on the street it would be even worse since its lighter than the truck (less load). The viper took 8 seconds from 1800RPM to 6000RPM to make the dyno pull and the truck never took longer than 5 seconds even on the lowest boost settings to make the same pull (only 3.5 seconds on the race gas pulls).
Water injection is not needed on race gas boost settings, only on pump gas settings, and the C02 sprayer was never turned on, the IAT's were in the 60's-70's without it.

i personally wouldnt see a need to spool any faster than this....ill post a video of my truck on the street tonight and you post one of yours and we will see who spools up faster or better yet you could be at the gtg in phoenix and everyone there can see that this single turbo setup spools right now...no waitin no lag this thing is on it.....Stinker said:Justin I think you did a helluva job, but a single turbo takes longer to spool than a smaller turbo. I run 67mm turbos
And I am not saying meth or co2 is bad, I jsut personally have never liked it,to me its jsut one more thing to worry about breaking, Eddie and both Jack will tell ya that
