What to do

[Steves LX]

O.K. guys I haven't really really messed with it much but after running 11.90@ 118 last week at Kil Kare and then makeing 2 passes at Pinks All out in the 11.90's at 120MPH something needs to happen here. Why are my ET's so slow vs my MPH? I am running on a 26X8.5 ET Dragg right now with a 3.73 gear. I am spraying 125 shot. Should I run a 28" slick and if so what actual size? The wheel I have now is a 15X8 draglite 5.5 B/S. I dont know how many people approached me this weekened up at Pinks in Norwalk and said why are you running those times with that kinda MPH. You should be running low 11's. I'll admit my 60's aren't the best but I still 'aint comeing out of the hole that bad. My 60's are anywhere from 1.61 to 1.70 and still the same E.T.'s and same MPH. 11.90-11.93 @ 118-121MPH.

You launch on the bottle? Your 60's could be better..but they aren't real bad. There is another 4-5 tenths to be found. How is your driving? Are you powershifting? 3.73's with a 26" tire should be fine. What's the car run n/a? Your spraying a 125 shot? What kit? What's your nitrous tuneup?

[outlaw85]

IT'S ALL 60 FT. IT SHOULD BE BETTER THAT WILL LOWER MPH AND ET.

I'll be the first to admit my driving could be worked on a bit. Yes I am powershifting. The car runs 12.40's N/A. Its a Zex Dry kit. 12 degrees initial on timing and 40PSI on fuel. NGK T-55 plugs gapped @ .035. 93-94 octane gas.

[Jeff88coupe]

Have you ever dyno'ed it to see how much power your actually getting to the rear wheels from the 125 shot? You should be able to pickup about a full second in et and 10-12 mph with a 125 shot from what you run n/a.

[Steves LX]

no I have'nt dynoed it with the spray. I did dyno it just N/A it put down 287RWHP and 325TQ. I am spraying from 3000 - 5900 RPM's. I am launching around 5000-5500 RPMS and it seems like my 60's are no better on spray then what they are on motor. I would love to try 150 shot but I don't know what fuel and nitrous pills I would need. The Zex dry kit is only good to 125HP.

1 word......






PROCHARGER

or VORTECH




their both one word









:D

[cstreu1026]

I would say you need to get on the dyno and get it tuned. You may be leaving a lot of power on the table.

I would say the best thing to do is switch out the ZEX dry kit for another brand. The Zex dry kit is 125 flywheel horspower where NX and NOS rate there kits by RWHP. I have never seen a car with a zex dry kit run nearly what it should. I would say a switch to an NX dry kit on the same shot would net you 4-5 tenths. My stock longblock car ran 12.0's on an NOS 150 shot with a stock gear in the rear. Just get the car on the dyno and see what it does on the spray I would say you will be lucky if the car picks up 60RWHP on that zex 125 shot.

[outlaw85]

MPH is HORSEPOWER! NOT ET!

[Timido]

That 12 degrees inital timing sounds a little high to me for a 125 shot. You are making real good Power by that MPH. The dyno might show you some power but I think there is a lot to be gained in the 60ft 330ft. You make enough power to be in the 1.5s maybe dip into the 1.4s

What Rpm are you going through the traps at?

[8banger]

Agree with the 60 foot comments .....Its all in the 60.....your E.T with a hard hittin launch should be a high 1.40's or better.... so....thats a solid 1.5 in just the 60...you do the math....gotta launch that thing(harder and make it stick)....:bigthumb .....

ive got buddys that run that kind of timing with there nitrous.. as long as it dont cut out im sure its alright

[ibstrokin]

A c4 would make a big difference. When I switched, I picked up .3/sec in the 1/4, .1 sec in the 60'. It actually made my car easier to drive around town, sucked losing overdrive though.

[outlaw85]

The stick will always win over the automatic but you have to drive it right and have the suspension to hook a hard launch. you can email me about your suspension if you want it to hook better.

Amen brother....:D

There was a local guy around here that went 10.0-10.1's on nitrous, 5 speed, and swapped to an auto and went 10.50's... I thought, man, you must need to run deep in the 9's to get the full benefit of an auto. :rolleyes:

[Timido]

Auto is more consistant and has more off a strong push than a violent clutch car. That softer hit is alot easyier on parts. With the right clutch you can do wonders also. I think you should start making minor changes one at a time. Try to get the car to leave and 60ft better.

[Steves LX]

Trust me I am not spinning when I launch. I have been yanking the wheels off the ground everytime no matter if I launch at 4000 or 6000 RPMS. The car isn't spinning on me. The only thing I have yet to do with my suspension is my torque boxes. I'm not running the best clutch in the world but I did that on purpose to make it the weaker link since I am still running stock 28 spline sn-95 axles. I know Norwalk hooks. I proved that Saturday after they rolled me to far beyond the waterbox and I didn't get to do a burnout. I staged and launched at 6000 RPM's on the spray and the car came up in the air and ran 11.93. If its spinning I can't feel it.

[dedpedal]

I dont know the answer Steve, but on a 100 shot, my car went 1140 at 119 with low 1.6 60 foot times.Are you driving foot to the floor all the way down the track? compared to mine, it seems your missing something in the middle of the track.

[Steves LX]

Yeah I am missing something. I am going to run it a few more times in some descent weather and see what I cant do. I really need to take a day and pull the cam out of the car and see what size it really is. I was told when I bought this motor that it was an X cam which I know for a fact that its not. I was leaning more along the lines of maybe an F cam but I am really not sure. It seems like from the 1/8 mile on this thing really starts to pull like a freight train whether your spraying it or running N/A. To just be driving around on the street and go from 5th to 4th the way it pulls in 4th you would think you were in third and the same can be said about third gear. It feels damn close to 2nd gear once you get around 3000 rpms.

[mustangboy]

Just out of curiosity have marked the tire and rim to be sure the rim isn't spinnning in the tire. Do you have rim screws?

[Steves LX]

Yeah my slicks are screwed in.

[Timido]

I would up the air pressure or tighten up the front sturts if you have adjustables. Sounds like you need to hit the tires harder or get some wheel speed. What RPM Through the traps? Maybe you need more gear.

[orangecoupe]

The whole problem is the car is not hooking as good as you think it is, 1.6 to 1.7 60ft is not good at all for your MPH. With that MPH you are making good power and could run 11.30 to 11.40 if you can get your 60ft down to at least mid 1.5's, high 1.4's are possible. My car on the motor runs 11.30s/11.40s (in the heat) at usually 117 to 119mph, my best 60ft is 1.44 and consistantly 1.46 to 1.48. I have a tremec in my car. Hope this helps.

[Stangman]

But your car being a coupe helps with the 60' situation doesnt it?

[orangecoupe]

How do you figure Josh's hatch went 1.42 60ft Saturday, and 1.25 60ft with mickey thompson drag radials with his old motor.

[Stangman]

dayumn! I just always thought that coupes 60'd better than a hatch...

[outlaw85]

60 ft. is the problem when your 60 ft. drops down so will your mph and et. what is your suspension setup front and back. You can build all the hp. you want but if you don't put it all to the pavement it's a waste.

[Drivermod]

The 60 ft is part of the problem but even with low 1.6 60 ft's you should be faster with that mph. Keep working on your shift points. Maybe your clutch is slipping. You said it was the weak link. Nitrous makes incredible amounts of torque. In the vidoe in your sig it looks like you either lifted or bogged in first gear and then short shifted. Clean up the front half of your run and you'll be flyin'.

Nothing super special. I am running Strange 10 way adjustables front and rear. 4 cyl springs up front. Lakewood lift bars and steeda uppers in the rear with GT springs and a air bag in right rear.

That run in my video is the first time I sprayed out of the hole so I had my guard up just in case and I only launched at 4500 and the car car bogged off the line. I didn't short shift it. After it bogged the nitrous kicked in and it was time to hit 2nd gear which was 5800 rpms when I shifted from 1st - 2nd and so on.

OK THEN JUST LET ME KNOW IF YOU NEED IT FIXED!
