Sweet looking car. Are you going supercharged or turbocharged?

Regarding your Vette, most modified cars I've read about that are going mid 8's in the 1/4 are running in the 190's or higher in the half mile. Is there a reason the mph is where it's at on the Vette?

Thanks for the compliment. I'm going the supercharged route.

As for the 1/2 mile speed, traction was NON-existent. 1st and 2nd were useless. I'd start hooking in 3rd. I do think the vette can go 200 mph in the 1/2. Point in fact, on the 181 mph run, I had a 56.36 mph increase between 1/4 and 1/2 mile speeds. Here are the stats from that run:

60 ft - 2.538
1/4 ET - 12.797
1/4 MPH - 124.79
1/2 ET - 18.595
1/2 MPH - 181.15

There are few events coming up, so we shall see.

Here's a short update that's focused on making the car put down the power as well as excel in both a straight line and in the turns.

VMS's Rear suspension upgrade:







VMS's front suspension upgrades:







Gotta feed the beast - upgraded fuel system components:

It's number 1240. I believe the original owner purchased it from Vintage around September of 2013.

Thanks! I think my choice of colors in order would be:

1. The same gray as the OP's car in this thread, all blacked out without stripes
2. Tour de France Blue, all blacked out, no stripes
3. Traditional Indigo Blue w/White Stripes
4. My car lol

I do love how menacing the all black (mainly) looks on my car. I got the dreaded Backdraft crack in my windshield, so I ordered a polycarbonate replacement. It's getting 50% tint applied to it now, so the car should look even more menacing with it installed!

Will you hurry up and finish this car so you can get tires of it and sell it to me!!! Damn! So sexy.

That made me chuckle! Trust me, I'm exercising all the patience I can muster. VMS has been doing a great job keeping the the project moving forward with the smaller items. As is almost always the case with semi-custom/custom builds, there are delays from other parts suppliers (e.g., supercharger) and there are some custom items that are taking time to engineer (e.g., half shafts from Drive Shaft Shop).

Can you give me a least until April/May to get the car and put a few thousand miles on it before you show up at my door to take the keys?

p.s. I checked out your BDR (here's the link to VMS's photos - The Gallery / Roadsters / BDR1240 | \\VINTAGE MOTORSPORTS ). Sick car!!

Deal! You have until the end of May. Or if you'd prefer, just bring it to the Pikes Peak Airstrip Attack and run her in the 1/2 mile in June. Then drive it 10 minutes to my house where she can stay lol

Trust me, I've searched through the entire internets to find every picture and video of my Cobra that exists. Btw, I left the number 6 on the side of the car for a total of eight hours before taking the heat gun to it; I was very thankful that it was only vinyl (one of the key questions I had before purchasing the car).

I'm envious of your Vette too. The first car I ever bought was a 2006 LMB (best color available) Vette. I did FBO followed by a D1SC within the first two months. It was a fun car for a 20 year old.

While we are waiting for the go fast parts, VMS is making sure Mayhem can stop just as well.

Small update - the build continues. As it gets closer to the end of the tunnel, the devil is in the details and those details take so much time, especially to the level that VMS will sign off on. Without further delay..here are some pictures:

Some trick headlights are going in





I'm really liking the lines of the car and look at those meaty rears!



Some of the devilish details..



Ginormous intercooler signals that summin' is up - but black it out and Bruce Wayne steps in

That 60 ft is terrible, and that hurts your ET. Your trap speed is basically what a stock C6Z would run. I don't know what altitude you are at, but I'm thinking you need more power to hit 200 in the half. I'm not sure you'd hit 200 in the 1 mile, though it is only 19 mph, you are covering some ground fast. You'd have to gain that 19 miles per hour in less than 10 seconds. In general traction hurts your et, but doesn't significantly affect your trap. Just my general experience.

I'll agree the 60 ft is terrible because I had to roll out in 1st spinning, then grab second spinning and just as i'm hooking, I'm at/past the 1/4 mile. And the 1/4 ET is slower than a stock C6Z. I know because my car has run 8.5 at 160+ in the 1/4. Trust me the power is there. But I'm curious, what have you run in the 1/2? I'd definitely welcome input based on experience.

I've never done the half. We have the mile down here in Texas, and if it wasn't booked I'd say you'd have fun participating. Most of my racing has been on a 1/4 mile strip, an SCCA. My C5Z was stock when I ran it, and it cut 1.8 60s and 12.51@114 through the 1/4. I did some modding but never got to strip it. I live in between 2 drag strips, and both are 2 hours away, so not to accessible. Now that my girls are older I'd like to strip this Cobra just to see where it is at. I'm thinking 11.0-11.3 at around 123 or so, but I need to run it to find out. Ive been running SCCA solo to burn these tires out, but they are rock hard.

So those times are from your run at the 1/2 mile? Why are you 40mph slower from your 1/4 mile runs?

Yup, those are from the 1/2. As said, my brass ring in the 1/2 is 200 mph. As for the speed differential - fully prepped, sticky 1/4 mile drag venue versus incredibly crappy airport runway surface and no traction management. As a point of reference, Sal Patel (who currently holds the US 1/2 record with his Viper that's run 6's in the 1/4) didn't reach 200 mph on that track that day. Sal had ProEfi working its electronic butt off that day - you can hear it in his videos pull power well past the 1/4.

Where does that leave things? Me being a keyboard crusher at the moment. ha! I'll be sure to post up my runs in the next few months. Good, bad or indifferent.

p.s. I don't have the stones to run the vette in the 1 mile - my car will run far faster than I'm willing to run it. I give mad props to those running the crazy numbers. Heck, others are run 247+ mph is the 1/2 mile these days. The landscape has changed. I will live by my brass ring goals vs. the crazy platinum numbers folks are posting these days. Great fun and times to be a speed enthusiast. Cheers.

My BDR is Build 784 with last 4 of con being 1165.
