Im not sure if they make that much of a difference or not. But they did make more power on the dyno, and my car feels amazing right now. |

There are some 17" wheels that will fit and this is key. You get a taller tire and they're less expensive.

I just realized that you may be running an aftermarket intercooler. Did you notice any improvement at all with that? Any HP increase estimates?

I just picked up my V3 from Tek818.
What a cool guy! I might make it to Irwindale Speedway this Thursday, but that's only the 1/8th. The thing that's great about the 1/8th is practicing the launches. For as much power as we have, I believe that if we get 1.7s on the launch then we are hitting low 12s easily in the 1/4. 1.6s are possible 11s. I'll keep in touch, and great job again, Digital!

Less than perfect launch is understandable without DRs, but shouldn't the trap be better? Stg2 V3 + IC...
Are these the best V3 results so far? |

He ran a 12.86 at 111.8 mph.
Interesting because I ran 12.38 at 111.8 mph, but I had a 1.8 60 foot.

Being that he was on pump gas and admitted to not shifting hard thats a pretty good trap. Race gas makes a very large difference IMO at the strip. The car acts like a puppy on crack when you put in the good stuff .

for example: I ran a 12.79 at 113.5mph w/ a bad launch and short shifting at 5000rpms in 3rd and a limp mode in 4th before the finish line. my 60 foot was over 2 seconds. The very next run I ran a 12.62 at only 110.xmph and even shifted into 5th gear on that run! The difference in the et was due to my 60 ft being in the low 1.9x range. Even w a very short shift in 3rd and 4th (who the hell shifts in 5th gear at the strip) my car still put down its best et to date. Cant wait to run it full out with slicks..... Moral - 60 ft times are huge.

So, if you would have had the same 60 foot as him, theoretically, you would have trapped higher. I have ran at the same track with Digital James, and it's a fairly slow track. I ran 12.85 @ 111 mph with just V2 and race gas (92% values), but my 60 foot was 1.85.

I believe the reason my trap is so slwo is because I almost run into the rev limiter in 3rd gear on my runs, so I short shift into 4th about 50ft from the finish line. Car is not geared so well for the drag strip with my 19s on

For example, the given D=VT. Let's look at comparing different 60 foots (1.7 and 2.0): 60 foot = V(1.7 seconds) V = 35.29 feet/second 60 foot = V(2.0) V = 30 feet/second The velocity of the 1.7 60 foot car is greater than the velocity of the 2.0 60 foot, so therefore the velocity should be carried along to the end of the 1/4 mile. Now, I know that what I did is very simplistic because we are talking about acceleration here and not just a constant velocity. But what is acceleration? It's the derivative of Velocity, which is the change of velocity over time. So, do the same thing as above and you'll get the same answer because time is 0 at 0 feet. I still understand though that it seems to be the oposite when I start comparing slips. I have had plenty of run with great 60 foots and the trap is 90% of the time lower than the traps with high 60 foots.

This means that we are bound to see solid 114-116mph runs with slight weigh reduction, race gas, race gas map, drag radials, cold temps, etc. Good job OP! Shiv .. Still on vacation |

On my car, 3rd gear will only take you up to about 100mph, so you need to make the shift to 4th gear. My car runs about 12.83 @ 110.43 on 91 pump gas and 19" and on street tires. With the R switch on and fuel I gain major HP. (113-114mph). But if I could really gain 18hp with an intercooler and intake, that would push my car to about 112mph on pump gas. That wouldn't be bad at all.
By the way, they had a build up of the new Challenger 6.2L Hemi with a Diablo Tune, Borla, and CAI. They said they were "so close" to dipping into the 12's @ 109mph. Let me tell you, how great is it when our cars can run with engines twice the displacement of ours!

The speed you are going at the very end of the 1/4 mile is higher than your trap.
