My friend and I headed out to a meet for another forum tonight. On the way back home, I decided to tease him and do a ricer fly by. I slow back down and move over a lane and he lines up. We slow down to about 45mph. I'm rolling in 2nd and he said he was in 3rd. We both jump and I start pulling. I shift from 2nd to 3rd, traction light comes on as I bark the tires and start pulling on him some more. I quickly hit the traction button and shift to 4th and I'm still pulling! I go to 5th and finally shut it down around 120 or so mph. he said he shut it down around 110mph.
I was truely surprised that I did so well against him. I was expecting to be raped with him having the 4.56 gears and more mods. He thinks the JLT RAI slowed his car down and is thinking about switching back to the stock system. Both cars are going to be tuned Saturday so it will be interesting to see where the truth lies.

I shifted before 120 into 5th. I've never been able to take the car to 160 in 4th. I did have some trouble going into 5th though. and looked down after I got into 5th. maybe I was going faster than I thought before 5th? Dunno.. defanitely wasn't 160! Takes a while to just get up to 140!
Odd that you shifted were you did...Sound's about right though considering his gearing. 4.56's are pretty steep, Defintly not roll friendly (2nd gear will only bring you to like 54mph with those)
mmmm..... Either he's in the wrong gear or traction limited..... with his better low end tq and gears .... he should've raped you by a good margin.

45mph is a very crappy speed to start at with 4.56's. Although I agree, he either granny shifted the thing, just ran out of gear all together (very possible)
good kill man. it will be interesting to hear the #'s.

Nice kill. would've thought the other way around but maybe a poor starting mph, wrong gear, lack of traction, and then running out of gear can explain it.

Nice kill. A stock geared mach would have been a better race for you at a roll. With my mach 45mph would have put me in 2nd gear @ 4000rpm(sweet spot).

You would have a very hard time convincing some people on this board of that. It is a fact though. That was a "bad" rpm for him to start at, but nothing to take away from your victory. That's the price you pay for some of the mods people do. Honestly, that's one of the reasons I am an advocate of making more power, and not going nuts with gearing. That and I want to shift as little as possible.
Gearing is good, but there are a LOT of factors to consider, but there are a lot of people that love to say, don't fear the gear, or 4.30s at a MINIMUM. Your kill is exactly why I don't think that philosophy is true. If you want to run 1/4 mile passes only, the more gear is usualy the better up to a point. More power is always going to get you where you want to be!

I gotta agree with you all on me having the advantage at a 45mph roll. The Cobra seemed right at home in 2nd at that speed. I don't know where his RPM's were though. I might sound like a wuss on this but he's not going to catch me launching from a dig. I refuse to do that for a while until I can get the girdle and other mods completed on the IRS. Last thing I want is to launch and have the diff grenade or a half shaft break.
Before he did the gear swap, it was a different story. He would pull on me. It will be interesting to see what happens after the dyno run. If he loses to enough rolling runs, there might be a set or 4.56's for sale shortly.

I beg to differ - I have 4.30's In my Mach, and I would not want to go at it with somone at a 55mph roll, that is to high for second and to low for third. And the same goes for 4.56's. Yes, I understand that they help with the initial hit, but with the 4.56's, what do they top out at in 4th? 115? That's Low for a roll race, and we all know the race is over once the top of 4th come's up, unless you have somthing speical planed for 5th.
Looking at both cars, the Mach 1's gear ratio is no longer a 4.56 due to the 18 inch tires. You would have to post his tire specs (i.e., 295x35x18), then we could determine with a calculator how the gear ratio characteristics have changed. My guess, the characteristics are similar to a 4.30 - 4.40 gearing, which is still very good. Just the same, the 4.56 gearing resulted in the lower dyno numbers. I would venture to guess he was around 3500 rpms when the roll race began which is below his sweet spot.
Your extra 10 rwhps helped, but we do not know the weight of each car. I would think the weight played a factor too.
Finally, driver's ability is a key factor in these two closely matched cars.
Nice kill...

I don't know what's going on, but those dyno numbers for the Mach 1 look like STOCK numbers, not those of a car with a JLT intake and an O/R x-pipe! The one thing I am sure about is the Predator "canned" performance tune sucks. It may be what's hurting the performance of the car. He would be much better off with the stock factory tune, tweaked for the intake and exhaust mods.
