ESS 575 vs 600 vs 625

[Longboarder]

Thanks for clarifying I believe we are in agreement. I have only had 3 opportunities in a DCT M3 so far, and none involved the drag strip. Although I did try launch control once and failed miserably. I'm looking forward to the opportunity of learning how to launch/track it.

I'm also looking forward to the opportunity of testing the car in various forms (with the V-Box). First will be stock to get a baseline. Next will be with the Procede/Meth. Then with the blower; then with blower + meth; then with blower + meth + ???. Who knows where it will end.

As you know a lot more power can be extracted without touching the pulley/tune. A full exhaust and meth on an ESS 600/ VF 620 can add quite a bit of RWHP. Getting some lightweight rear wheels would also help quite a bit with the lower unsprung weight...some other weight reduction (removal of passenger/rear seats), better gas...oh, and of course what m33 said above about changing suspension settings. His delta of 6.8mph is pretty amazing but I wouldn't think this is the norm.

So with the additional power from supporting mods, weight reduction, suspension changes, and of course a lot of practice, all this could worth 10mph (even assuming similar 60ft times) don't you think?

Some good points, I'm honestly looking forward to you getting your M3, and I had a nice time chatting with you about possibly supercharging it a few weeks or so ago over the phone. When you get it, let's hit the track together if possible, maybe we can setup up another private event through MO at Famoso, I think your plan of attack is a good one and I'm anxious to see the results.

I need to get some more miles on my VT3, make sure the clutch holds, as well as a linelock, and I plan on going to the track again at the end of the year when it's cooler out, so if you go I'll join you. Until then looking forward to the shift-s3ctor event, ESS will be there, it would be great to see other supercharger companies there as well, I know you were thinking of the different setups, this could help you with your decision.

1) your 6mt 535

3) VF620 is DCT ????
And Larry put 3-4 cars on you meanwhile the VF barley put 1&1/2 cars on you ,shit you pretty much stood side by side until the end where he nosed ahead of you ...
Pretty impressive !!

thanks... track was terribly prepped. thanks LVMS for the crappy job that night haha. i had fun but would love to get more practice at a good track. too bad nothing near me

Undoubtedly, all 3 cars are fast.

i agree... my car oddly makes more power than most and that all 3 cars are fast.

i think track prep had a lot to do with the subpar times also... at one point in the night i spun violently more than halfway down the track and almost hit the wall. even Marcus' proEFI noticed how terrible track prep was.

I've been drag racing for over 12 years. I'd like to say I've had my fair share of seat time, just not enough in this car and even less with the supercharger. The hardest car for me to get down the track before this one was my Integra since it was front wheel drive and had a lot of power. I ran a 11.90 at 119 mph. I was able to get a 1.8 short time out of that. THIS car w this transmission is harder to get off the line even though it's rear wheel drive. I need some tires and need to practice that launch, and hope for better track conditions next time.

[m33]

I'm not a drag racer either and when I first went Down the track with my vt625 MT I would trap 117-119 regularly until i dedicated 1 full day at Atco which I did a Total of 52 runs and the last 4 runs is where I actually started to understand how to put the power down and my traps started climbing up to 120 - 123- 125 to my final best 126.8 mph so as you can see it takes great practice and understanding of your car , it doesn't seem like your car is down on power it's knowing how to lay the power down and making it work !
Practice , practice and more practice

[NFAM3]

You right m33. I need practice. Maybe then my 12.2@123 isn't so bad after all considering I was on 20's and it was my first time out. I need practice.

um... yea, 12.2@123 isn't bad on 20's ... Get some proper tires. And thanks for jacking my thread

[NFAM3]

My bad. I'll buy you a beer!!

you went to the track with 20's ??? no wonder your traps and times suck

sorry for the thread track

[tibra1]

A 4 page thread on why to spend $11K vs $12.5K vs $14K

If you're determined to spend..and at this level of spend... is $3K really a deal breaker?

In for a penny in for a pound,,get the best setup..

And posts here regarding price inflation of these units compared to other platforms is spot on..but the reality is there is a market..you have guys willing to shell out this kind of money for a blower setup on an M3...thing is once you go down this road you have to mod suspension..drivetrain etc..

Post a slip or 2 and we can look at it a bit more. lots of us have more experience in drag racing than our wives and bank accounts would like to admit. With that, it spans over more than 1 or 2 cars. Realistically, you can/should expect 125mph, give or a mph. Rest assured, 130mph is not realistic for an average end user.

VT2-625 DCT will surpass 125mph trap with the tracks around here. And you are incorrect, racegas makes no more difference than 10-15whp these ESS kits can only take advantage of around 98 octane or so (and for the 100th time whether you want to believe it or not there isnt a race fuel file only). I had no problem staying above 130mph when I went, and that was my first time out with the blower. Times will improve this time around with traction in 1st.

Maybe if he had a 6MT he would run the same times too since the DCT has no advantage right? lol

NFAM3, nice job for your first time out. Keep at it and youll figure out the car more and more and be able to squeeze out more mph. Botching the 2-3 shift for me costed me 2mph last time I went, dialing in the little things will net you a great time

[NFAM3]

I'll tell you one thing for sure! The car moves. On the way home, I messed around with it a bit and the car does move great. Velos did a great job on this car bw the kit and the brakes and everything else they did to it. Everyone was giving my friend Berto and I compliments on the cars. I look forward to lowering my time. These guys know what they are doing over there.

+1 why complain about things you can't control

Just start with a 575 kit. It's more than enough. If later you feel its not, they can upgrade. To me, that's the best way. If you do it all at once, it leaves nothing to strive for and gets boring (modding, not actual power)

However, it's completely reaslitic to hit that in negative DA, and it's realistic even for an average driver to take a DCT VT625 and hit 130 at a track like ATCO or MIR in good air.

I think we are on the same thought process, but for different meanings.
When I say average, its just that. 112 stock trap, add roughly 130hp, should be about 125 trap. That to me would be an average expectation. But as you said, a lot of other factors can affect it, both up and down. An average expectation

That's what I don't understand about changing the differential. Why if lowering the final drive ratio from 3.85 to 4.10 increases torque, it is not good for drag racing? Is this a general rule or is it just your case because of the supercharger with substantial increase in tq and hp causing more wheelspin/less traction? Or is it because you'll hit redline faster because of the 4.10 diff, making it more difficult to shift adequately? Some light in this subject will be appreciated.

Thanks!!

4.10's are good for drag racing, but only ET,

That's what I thought.
