So you are saying you can hit low 13's with just cutouts and vararam? And we are talking a v6 camaro right?

No disrespect but my money will not be on you. What makes you think the cutouts will give you so much power? It will help to scavenge but how far do you think that's going to take you?

Forget the time calculations, I am more curious to hear why you have so much hope that cutouts will all of a sudden make your car faster then everyone else's?

With some practice you should be able to get that 60' down to a 2.0x. This will really help bring down your ET.

How are you launching?

Hey scrming,

Sorry I havent gotten back to your PM btw- congrats on all the success you're having with the twins

My launch was rev to 2500 or so, then drop clutch and floor it. The only successful time that worked was this time. Every other time I either spun or had severe wheelhop. I also made 6 passes that day. This was my first pass, and also my bet E/T. I believe the clutch was too hot by the end ( I only had to wait 15-20 min between passes). I did a very mild burnout before each pass, really just to clean the tires off and add a little heat.

Do getting closer to a 2.0 60' will help me the most? Should I not rev at all before launching next time?

You shouldn't be shifting into 4th yet 3rd finishes at like 104 or something. When I trapped 101 I was in 3rd. As for the cut outs they make more power than a cutback. Not a whole lot more maybe like 5-8 more wheel untuned. Its not just cut outs either its lighter rims and tires. My stock 14.35/14.18 was with the 20s. Going to 23lb 18s and lighter tires drops you almost. 5 tenths.

edit damn phone typos

cut outs, vararam and lighter rims/tires yes. 101.5 trap speed is indicative of about a 13.3 run with a proper 60' foot.

I don't believe this, I shaved 40lbs in wheel/tire weight and it helped my 1/4 mile only marginally.

Every pound you add or subtract to your wheel/tire set up is the equivalent of roughly 7-8 pounds.

So talking about the rims alone and not even the tires, the stock 20s weigh about 30 lbs while the 1LT 18s weigh 23lbs.

That is a saving of 7 pounds per wheel. 7*8=28 pounds saved.

Once you apply some physics and rotational mass and energy equations you can multiply that number by about 8. 28*8=224.

So just the rims alone, not talking tires, is like removing 200lbs from your car. Every 100 pounds will net you approximately .1 in the 1/4.

If you get equally as weight reduced tires youre talking a 400lb decrease.

AND if you get slimmer profile tires you get a simulated better gear ratio as well which nets you maybe .05-.1 tenths. So theres your .5 reduction.

There are a number of reasons you may not have seen a sharp enough drop Id have to se everything youre running.

Anyone who knows the numbers behind drag racing will cosign what I'm saying its no secret. Its just basic physics as well.

Remember as well that when I say .5 tenths its if you reduce from the RS/SS rims. If you had say the 19s or something its not as dramatic of a decrease.

Might want to check your math again. Got some errors.

I follow all the logic. I know because I have used it myself for understanding theory.

With that said, these are rough figures for THEORY only.

Now you need to go prove it to us.

GOOD LUCK.

Typically when I multiply seven by eight I get 56. I've been known to be wrong in the past though..


Alright bud, can't wait to see your 13.0 time. Who knows you may even get sub 12's! What you're talking about it theory, I've learned A LOT of theory throughout my time in school. However I've come to realize theory and practice usually differ. Just say'n.

Thank you but I mean a 101.5 trap speed at Island, a slow track, is almost always representative of a mid to low 13 second car. you can trap that high unless thats what the car can run lol.

I kinda have proved my theory I just couldnt hook lol.

I guess everyone's just waiting to see the slip and until then we'll just keep doubting your ricer math. I'll be happy when you can get to sub-14's.

I have a 1.9 60' and a 102.2 trap what will my 1320 be?

I'll post the slips if you guys want. The bad is I only ran 14.4, basically the same as stock.

The good/bad is that I trapped at 101.59 with a 2.5 60 foot!

Every .1 off your 60' is roughly .2 in the 1/4.

So essentially with proper tires I'll hit about a 13.45. Also at island dragway, the track I was at, cars typically run .2 tenths slower than tracks at sea level.

So although I didnt actually get a slip with the time, it seems that just with 1LT rims, lighter tires, vararam intake, and cut outs on stock exhaust My car can run about a 13.2-13.3.

Im going to go back with drag radials but unfortunately Im probably going to wait until early spring.

With radials Im sure I can cut a 1.8~ 60' which should land me right around a 13.0 MAYBE a 12.9.

This is all without headers, a tune, or the weight reduction from removing the stock exhaust.

Discuss....
