Going for 500whp N/A

[mustang_guy]

Lol you are sorely mistaken. What do you think a base s550 weighs with full drag pack, k member with manual steering rack, racing seats etc....

Because at one time he claimed it was over 4k he started out as a loaded premium last I recall. Base manuals have weighed 3680 and base PP start at 3730s. Watson k member kit only removes 30lbs. Rear brakes, hood, some interior pieces, 15 inch rears and 17 skinnies doesn't subtract all that. He also wasn't some skinny 150lb driver If you've actually seen pictures of him. If he's removed 500+lbs I haven't seen it documented all around here. Pardon me. Im glad you think I'm some drag race newbie when I'm actually a drag race veteran.

I think the point is RBS550 is several hundred pounds lighter, runs FTW fuel, and has been fine tuning the car with data from the track with Lund for a good while. He has the car geared, with a good stall setup and figured out how to get the car to launch well. We have never even seen any good dyno info from him to see how much power the car is making on FTW. My car with a very similar setup makes 458whp with a GT350 mani through a manual on e85. With a cobra jet mani on FTW and a damn near perfect tune RB may be making about 500whp. Take the DA, weight difference, tire, launch, etc into account and I can see the difference possible without thinking Evil's car is unimpressive for the stage that he's at.

Da doesnt play anywhere close to the affect when on e85 or especially FTW vs 93. 300lbs difference isn't 4mph difference. I'm definitely allowed to think my thoughts. Trap is a display of power generally. I'd expect for the momey cams cost, install and return, better yields. Thats it. I'm okay with agreeing to disagree. I don't think Evils build sucks or anything of the like, I would agree a gear change is in order. I'm just impressed with the stock heads and disappointed with cams for NA. I merely expected more is all. I'm not looking to suck up his thread anymore than this has. :cheers:

I bet if Evil datalogs some passes and sends the data back to Lund they can tweak the tune. I know RB worked a good bit with Lund with specific track data as he didn't care about dyno figures. Especially on FTW I am sure with some better tuning the MPH will come up. Other factors (weight, driver technique, tires, etc) will also show improvements. I think for 35-50whp cams are a worthwhile add to an all out NA build if your already going in to do OPG and CG. You mentioned expecting 133mph out of his car, out of curiosity how much power did you think the cams would have added to make up about 8mph with 300+ extra pounds? I would think that would take damn near 100hp. I know RB picked up a couple mph when he switched to FTW fuel. Thats when he started in the 10's. Evil needs to drop some weight, switch to slicks, and go to FTW fuel with a spot on track tune. Then we will see 130mph.

The point is RBS does not have a cookie cutter setup. There is far more into it than you know, hence why he runs a sec faster than most. The car is a race gas like mentioned, and it's light. So you can't compare evil to him and say evils is bad. If you are such a veteran you should have known that

You hadn't seen where he has posted his latest runs and info.

RBS55 told me DA affects NA cars the most, to include his. Your allowed to think your thoughts.... but I'm giving you facts.

If you have followed him and gathered facts, you would see that he has also stated their are A LOT of runs with not so great numbers, and the ones he has posted are some of the best. He has given me good advice and is an extremely nice guy with a hell of a car... that is fine tuned. DA also affects FTW fuel according to him. Have you taken the time to look up the thread I informed you about?

Is my car where I want it to be? No, not yet. I need work and so does the car. I have only been able to hit few good runs on two times out. Do I even know how to get the car to launch consistent yet? No

This thread is about facts. I don't just post fluff. It is a journey and I look for advice. As you, I have been doing this awhile, I have went mid 8's@160 and I don't know it all. This car is entirely different than my fox, and I look to some of these guys on here for advice and people are willing to help. I post up the results, thats it.

What gears are you running?

What gears are you running?

Currently 3.73. Debating trying 4.10's. Also a side note, the car has 19x10 rims up front and 19x11's in the rear. It is not an all out drag car.. so far.

Ordered a 4.09 today.

I will be getting 2 step with trans brake as well.

That's interesting. I had heard autos don't like that much gear??

Off a brake it will come out hard!

I was thinking that it may cause more wheelspin on my DR, but was told it actually decreases wheelspeed.

 

[V8EATR]

I would be careful with more gear, if you have to go to 5th, you will most certainly be worse off.

Changed my 3.15 to 3.55 plus Wavetrac diff some time ago. Then installed stage 3 comp cams. I have 295/30R20 street tires and I have absolutely no spin whatsoever with gas pedal floored - left foot on a brake.

This run was measured with Race Logic and I did 12.4(a bit uphill, over 35'C ambient):

I have 8100 redline - no worries...

8100 rpm in 4th with 3.55 ratio gives 258 kph
8100 rpm in 4th with 4.09 ratio gives 224 kph

I think my redline is 7900 or 8000 and we can raise it if need be, it was still making power up there. The redline right now is conservative.

Peak with S3 Comps is at approx 7800 rpm.
