Decided to go to beech bend today, to see if I could somehow finesse a little better run out of the car.....at least break into the 11s lol. So for the first pass, I turned the boost all the way down, and left the cutout closed. Netted me a 12.24 @123.29. I did that to see how the track felt.....felt GREAT so I turned it up, opened the cutout....which resulted in 11.85 @134.23. After that, I figured...the more the merrier, so I added a little more boost which brought on spinning serious spinning...which slowed me down to a 12.02 @131. All in all, a good time was had. I think of I can fight this t56 into the 10s, I'm going to put a 400 in it and see what the car will really run.

until? What's the best trap you've had at 800 rwhp, and what tires do you run?

Game ova

What do you mean "until"? Best so far is 134xx. Tires are 315 35 17 nitto street tire. This 134 that I ran today was at 18psi, the setup is good to around 22psi, so I'm guessing I was around 750ish today. Im fairly certain that when I get rid of the spinning....the trap will come around to where it should be. Along with a good rear end and a two step.

Sorry the "until" was a typo. Yeah I'm sure there's more in it as well. I wouldn't be surprised if it was closer to 140 mph after all said and done

you live in bg?

Nah, I'm in the ville. Just rode down for the rolls and digs event today. Where you there? And did you see that stupid fast 3rd gen??!

If the car 8th miled like it usually does, I probably would have seen 140 today. This slip is from an aborted pass a few weeks ago.

I think we have pretty similar set ups and this is the slip I got a few weeks back, it was my first trip down the track in 10 years. This was done on Mickey Thompson ET Street Radials and 16 pounds of boost launching on no boost. I think both of our cars have low 10s @ 140+ in them. I'm waiting on a bigger turbo to get here though.

Nice looking pass. Comparing slips, it's weird how you have me covered by almost a full 10mph at the 8th....but at the traps it turned into 4mph. I was reading a thread on here debating if spinning hurts trap speed....I think this pretty much answers that one. Only my opinion, but if you have a pt76 like I do along with 365 cubes. ..I think you could get away with leaning on it a little harder to get the desired results you are looking for. On my setup on rare occasion, I turn it up to 21psi.....and I don't think it's maxed at that level.

I'm running a 408 with a Borg Warner S476. I'm waiting on a S480 to get here and hope that opens up my top end some. My heads are just 317s also which I'll replace after the turbo. Both of our cars put down over 800 at our current boost levels.

I've also read that spinning increases trap speed but who knows.

I think the spinning increasing trap speed is very dependant. I always trap more the better my 60ft is.

What I said definitely wasn't from experience just what I've read so I don't myself. I guess it really could go either way.

The trap speeds are all over the place - indicative of feathering the throttle down the track. Trap speeds should be consistent - even with some wheelspin off the line. So the wheelspin must extend quite a ways down the track.

The car has potential for sure! Throw a drag tire on there.

I see what you mean. After 1st and 2nd, the car actually stuck. Shout out to the track prep crew! What I was doing was, after each shift...for a spilt second I waited till the tires were back loaded again before standing in it. Did this for a few reasons, #1 to keep from shocking the tires by ripping through the gears and having to abort the pass....#2 to keep from grenading the 10bolt.....#3 kinda goes with #2, I needed to drive the car back home..as I drove it to the track which is about two hours from where I live. Was told I was brave for pulling a stunt like that on a ten bolt lol. I say, that. ..and kinda stupid. I gambled and got away with it, so I'm leaving good enough alone for now.

This! My old setup:
2.0 sixty-119mph
1.8 sixty-125mph
1.5 sixty-130+mph

^^I think blk00ss is referring to fractions of a MPH, not 5 & 10 MPH! You obviously added power to go faster.

MPH is 100% dependent on the HP of the vehicle, assuming you are WOT every pass. A good driver will run the same MPH every run. A little wheelspin will affect it some, but we're talking 1 MPH or less.

so you know my setup better than me? I added ZERO hp. That is the power of real traction vs spinning down the track. The whole comment of varying less than 1mph works if the car only spins off the line and regains traction in a reasonable amount of distance. I've seen it on MULTIPLE cars where a complete and utter lack of traction until practically 1/8th mile will lead to huge descrepncies in mph. And if you're spinning until half track chances are you aren't WOT the entire run so it makes perfect sense.

T6Rocket

Yes, if you're pedaling all the way down the track, your MPH will be all over the place. 11 MPH is quite the difference, running bald street tires?

If you are 100% throttle the whole pass, every pass, even small differences in traction won't change the MPH much.

The 2.0 to 1.8 was the difference of 275/40/18" drag radials to 295/50/16 drag radials.

The 1.8 to 1.5 was leaving in boost vs. no boost (i.e. 2 step vs. no 2 step) in a 6 speed car. I agree if you are 100% WOT the entire pass everything will be reasonably close, but the OP stated he left off between each gear on top of spinning 1st and 2nd so he wouldn't have been 100% WOT the entire run.

I think the 11 mph discrepancy was mainly due to the boost turned all the way down, in addition to running through full exhaust running out the back (cutout closed). This was done mainly to see how the track felt, and to see what the car ran like with as much power as possible pulled out. I will say, once it hooked with the car turned up with cutout open..... it was an animal. Picked up almost 40mph on the backend. Can't wait to get the car finished, so I can see what it really runs like.
