135-140 traps with some 3.90's and a tire. That beast is going easy 10's, just need to get out of the hole with it. Thats what I am hoping mine will do when I have a chance to go to the track. Best of luck with whatever you do with the car, VERY IMPRESSIVE !! That has definately got to be the highest hp 402 out !!! WOW !!
If I were you I would hope for 127-128mph and be satisfied if ya get that.
either way sick power, and nice rides!

We went 125 on the old stock cube H/C motor. This motor has already been 102 in the 1/8th with the 3.42 gear. I suspect it will be around the 130-133 range in the 1/4 with the 3.73.

Call me optimistic on the high guess, but call you uninformed for guessing 120 anything. THat car will do 130 on a bad day. I'd put money on it. **** he's got me beat by 29 rwhp and that thing is definately pulling harder up top (5-7,000 considering he's got the 235's vs my baby 215's) then mine. Add those 3.73's or 3.90's and I can only imagine. Either way its going to be bad *** once it hits the street and/or track
How much timing would you have to pull to get her to run on 93 pump? How much power do you think you'd lose to run pump 93 vs 98 ?
Awesome sounding video too !

Yes I have been to the track, and if he feels a 3.73 will give him 133, I am going to say 3.90's should put him at the top of 4th for 135+

Dont mind the milling machine in the background noise. Those are throttle bodys being made
I think the car will make better numbers when we get some good air and the humidity down. The 570 was made with 95 degree air and 80% humidity.
As far as the timing goes, that would be a question for Nick, but on this run, timing was at 28 degrees with no knock.

The vacuum pump creates a slight vacuum in the crankcase to help with blow-by pressures from loose piston rings. Low tension piston rings create a minimum of drag on the cylinder walls, but the low tension can also allow blow-by. You can use pistons with gas ports drilled into the pistons to put pressure behind the rings for sealing, but this is converse to the original intent. So, the use of a vacuum pump pulls out extra gasses from the crank case. Too much pressure in the crank case can act like an air spring and cause resistance. In my case, I sometimes blow out the dip stick about 6500 rpm. Thus, my pump is getting installed to avoid this. A good breather system can be used in place of the vacuum pump. But, when you are going after that n'th degree of power, you fine tune everything.

I have 250cc intake runners and run 93 octane or E85.

I think the car is going to go faster then that especially with 3.90's With the right tire height you will be able to match the speed and rpms and cross the 1320 at the top of 4th !! Good luck. What tires are going to be on it for the street ?

With 93 maybe at the most 10 less hp.
As far as tires, I will probably run the BFG drag radial on the street and CCW drag pack for the track.
In the next few weeks I plan to add an electric water pump, 95mm intake and tb, and machine the heads to run 3/8 pushrods and better valve springs. Still having some valve float above 6k RPM.

Damn, those are outrageous numbers. You got me by almost 120 hp and 50 Tq. I have basically the same set up as Allngn except I'm running 225s (I do have an auto though). Love to see some track times to compare to these dyno numbers. Hoping to get mine to the track by the end of the month.

So are you sticking with the 130-133 trap estimate with 3.73's?
I think the car is going to go faster then that especially with 3.90's With the right tire height you will be able to match the speed and rpms and cross the 1320 at the top of 4th !! Good luck. What tires are going to be on it for the street ?
