No I have never taken the time to workout boosted cars.

That being said if I workout a simulation for your run.

60 Foot ET = 1.2410
330 Foot ET = 3.2494
1/8 Mile ET = 4.9263
1/8 Mile MPH = 146.5352
1000 Foot ET = 6.3736
1/4 Mile ET = 7.6004
1/4 Mile MPH = 184.1309

I have no idea for your combination how much boost increase will add how much HP. Let just add 300 HP and keep the 60 time the same. The 300 HP is on the starting line and would need to be weather corrected for a dyno number.

60 Foot ET = 1.2410
330 Foot ET = 3.1933
1/8 Mile ET = 4.7808
1/8 Mile MPH = 155.0522
1000 Foot ET = 6.1455
1/4 Mile ET = 7.2994
1/4 Mile MPH = 195.9008

Thanks Stan, We do expect to get the 60 down to at least a 1.1x. working on getting the boost up on the launch.

I'd love to have that time slip, since I'm certified to only 7.50 with my mild steel chassis.


Congratulations! Don't stop there.

Are you leaving off-idle?

The 60 foot looks slow but it's coming on stronger later.
Probably making boost gradually?

I would say it's got a lot more in it?

The 1.2x 60's will start to get better, getting used to the additional launch boost will take a few more passes. This was the first one. It's was a bit of a change going from 6lb to 10.7lb.

It's part of the Holley Dominator EFI ECU.

ok Im not sure how that one sets up but on the one I used it worked best by ramping up in small quick steps --all in by a second or less

Were you adding/removing fuel and/or Timing?

the boost controller was adding pressure to the back side of the waist gate in small increasing amounts very quickly -- the fuel pressure regulator added fuel based on boost pressure ie boost referenced and if I remember right timing was at about 25 degrees over 12-15 lb boost . Boost controller setup was 12lb springs in the waste gates and then every lb of c02 on the back side of the gate increased boost by aprox a lb -- data recorder will tell you exactly how much.

I’m thinking with the boost he’s running now he’s pretty darn close for a turbo car!

Most ET's I have seen around that time is usally 1.0x seconds?
(mine in my slow dragster is 1.09-1.15)
I suppose the turbos may be 'soft' on launch, but don't see why it should be.
The guys that are hampered by small tires would probably have slower 60' times.

It’s a learning curve for sure, and it looks like he’s going in the right direction.

As for small tires having slow 60’ times. Most decent 275 tired cars will go in the 1.10 range on decent tracks. A good one on a radial prepped track will go low 1.00s.
