Fastest 'truck' i've seen, all #2 and air thats a regular around here was 11.20 on a single s480. i think it trapped about 124 mph. big top end. That was no spray the entire run, though he was trying to spray it (had a bad solenoid or something). He backed it up with 11.21 and no bottle in his truck just to make sure any naysayers were put to bed.
He's not a racer though - he's a sled puller so doesn't come to the track much... was very impressed when he did though. Also - that was at our elevation - i'm sure he could pull off a better run lower elevation. Not sure what DA was that day, but sure it was close to 7000' or worse... never really heard of any days better than 6800 all year long at our track...
I think one thing that doesn't come into play, which has been proven i think over and over at the tracks in particular - is elevation.
Twins vs. Single - surely for 'all around' use, there really can't be a very good straight across comparison when you throw in elevation.
I think both sides of the argument have merit - however, i think when the "use for dd, towing heavy, racing, etc." argument gets used, and the poor guy doesn't live at sea level or within 1000' feet of it - the argument for twins gains alot of strength.
I'm not sure how many people can testify one way or the other to this - but i do know of a few people here, in Salt Lake running big singles. Most of you know them in fact on this board - but no need to toss names out. I know that one of them that put down about the fastest times i saw at our track on a single charger (Ken knows him too) had to spray more NOS than a guy should have access too - but it was still very impressive to say the least. His single charger does spool 'ok' for the elevation - but it still is nitrous assisted basically right off the line - point being there is no way this truck could tow more than about 5000 # without burning to the ground. EGTs at the track even with all the spray are off the chart.... he "quits looking when he sees 2000*"... I'm sure there's not alot of twinned trucks that have seen 2000* or much above - but i could be wrong.
Anyways - drifting off topic a little - point is that one thing not mentioned or factored in to anyones post so far, that i have seen - is elevation. If a guy is going to be towing up in the mountains, particularly with significant weight - or even just in higher elevations period - for 'all around' use, i just don't see how the argument for a bigger single could stand up. At the track, sure - with some help - but for all around use, i just don't see it.
For reference, for those that don't know - Salt Lake during the summer / racing months experiences usually 7200 - 7500' DA - a fact that has caught alot of out of town 'fast' trucks far enough off gaurd that they couldn't even get a single good pass in at some of the events (Edge Days, DHRA, NADM, etc.).
Are you talking about Mat Moon? He has a killer truck for sure, loved his explaination of his rear diff. Poor man's spool, welded the sucker!:thumb:
As for egt's all I can say is I see 2000 by the end of the track at 46 lbs of boost, I cannot comment on twin temps. Odds are my next step is twins but my new house may not allow that for some time.
bump....im thinking of running a S480 on the track.....from a tuning prospective, what are the major differences between big singles and big twins? i figure there's increased timing to spool the big single....what else? FYI this will be on a built motor - forged pistons and race cam and stage 2 heads plus some more extras. is picking a converter that difficult these days to put this power to the ground? how about other tranny issues - are twins more tranny friendly than the big singles? i want 1000hp on fuel if possible, i will use nitrous in high stakes races and learn to tune accordingly.
thanks trent. so is there any cheaper option for a big single to hit the 1000 mark on fuel other than a Precision Turbo? Tony Burkhard has built a few big single trucks that are around or above 1000 on fuel...i haven't asked him yet for specifics.
and i was a little nervous about the 1055 when i saw a crapload of them for sale...i am planning to use a Precision
How long will the motor last on twins? 100,000 Miles? For the normal daily driver?
