Awesome job Jake! Great for first time out. You had to have adrenaline pumping like crazy! Been long anticipated for sure man. What a great build. So much you can tweak for the track. You just have to figure out what you want to do. A shorter tire would definitely help and be an easy fix. I think you're running a 28" so 26" would be fun if you wanted to tweak something. I'd just run it the way it is a few times at the track and have fun. Congrats buddy!

What's the weight of the car?
With a 2.1 60' running low 11s this tells me your easily in the 10s, especially trapping 125. I run 11.90s at 110 with a 1.58 60ft, so your definitely 10s.

I have et streets, and they have a sweet spot on tire pressure and burnout. Just 2-3 psi or not a proper burnout can make or break the run. Mine seems to hook better with a good burnout vs the light hazing everyone talks about with drag radials.

Also, what rpm where you shifting?

I shift at 7300. I use a raptor light. It's funny but I didn't do it for the track. I did it because my tach stops at 6400 for some weird reason. Came in handy though! I have the limiter set to 7500

The car is light. Not crazy light, but between tubular K and the drag pack I know it's down a bit from stock. I pulled the spare out but I left it full interior.

Lol....my tach stops between 6400 and 6600. Phils old trans am did to.

Good job Darth! Not many can say their h/c ls1 went low 11s first time out!

It will go much quicker to. Can't wait to see how that develops!

Unless I'm the only one spotting this.. I guess it's the 60'-330' time.

How can this car cover that distance in the same time as a nitrous, six speed, car that has a 1.4 60' & traps almost 137mph?

Maybe it's just how the track timing is setup?

I really don't have much frame of reference for you other than this. Per Tony, it's 600 at the crank. Even so, Lacking nitrous, I simply don't have the torque on the upshift in the higher gears - especially going into 4th. I never got to peak power in fourth. But with the lighter clutch and alternator only, it revs in 2,3 almost like it isn't loaded. IMO, the back half is clearly showing where it's being limited.

But let's play the what-if game... what if I knew how to launch and cut a 1.6-1.8 60', got over 100 at the 1/8, and then backhalfed a little better just by being deeper into fourth?

Better gear, better tire, better driver, and low 130's might be realistic. But I'd expect the nitrous car to pull me up top in fourth all day long.

And that's based on VERY limited experience, so if I'm wrong I'm wrong

Not to mention +3600' DA!
26" Tires, some practice, & <+600' DA, High 10s @ 128+ as it sits!
Great Job Darth!

Curious if you know amount of vacuum @ idle?

iTrader: (4)

I don't, but someone could do the unit conversion. I idle at 65-70 kpa, so that's 30 kpa under atmospheric

Not saying your car isn't fast. As stated the car definitely has more potential. The back half is still strong knowing what's going on. When you get it in the right spot it will be faster.

The main thing was seeing a 2.1 60' with a low 11 et at 125 mph. It doesn't seem right. Then just looking at the slip & times. Your 60'-330 time matched a car w/ 1.4 60', 6.5 1/8 @ 107, & 10.0 1/4 @ 137. I don't see any way your car could match that time with that car. Or another car with a 2.3 60', 8.3 1/8 @ 104, & 12.1 1/4 @ 132. This car has about the same 60'-330' but look at the et & mph? It's a turbo car with a lot more hp.

I'm not trying to be rude. In reality If I saw a car run an 11.2 with a 2.1 60' I would say the mph would have to be higher than 99 1/8 & 125 1/4.

Can anyone find a vehicle that runs a 11.2et @125mph on a 2.1 60'?

What you're seeing is his oddball gearing. Right now 4th might as well be an overdrive so when he hits that gear it bogs out

SoFla01SSLookinstok

No, no. I get the gearing & what's happening on the top end. Everything seems right after the 330' with the time/mph/et stuff. It's the 60'-330' time that seems to be off. Think of his slip 2.1 60' with a 7.0 1/8 mile. Now just look at that nitrous cars time 60' 1.4 to 6.5 1/8 mile. Darths car makes that jump in 4.9 seconds, nitrous car 5.1 seconds. Sorry but that cant be right. Like I said the slip seems good except for that 60'-330' time. That's where it seems off.

SoFla01SSLookinstok

All in all I'd guess it's around .5 seconds off. Looking at a few other N/A six speed, low eleven second, 126-127mph cars.

jhshnh

My car has 321 rwhp and cuts 1.58 60 ft and gets to the 330 in 4.779 seconds and runs 7.55 in the 1/8th.
I think what you're seeing is extreme spinning and then when he hooks, he's rolling. He posted a short video of the tach while he got in it on the street, and that llsr revs extremely fast.
His car is a different animal from the HR cams we're used to.
If he can cut a 1.5x 60ft he's mid 10s all day long.

SoFla01SSLookinstok

Your car moves out.

Your car 3.2 sec. 60'-330'. His car 2.6 sec.

jhshnh

Thanks. That's with a stock engine... even ls1 intake. After the 330 everybody starts walking me down, but I'm planning on taking care of that with h/c/i very soon.

SoFla01SSLookinstok

Nice!

I'm pretty sure this is a 416 car.

That is interesting, his 60 ft killed him too. The car he ran looks really efficient, especially from start to the 330.

My car is an A4 with 4k stall, so I guess what we're seeing in both cases is spinning with the M6 past the 60ft? That's about the only way I know to explain it, or once the car hooked it was completely out of the power band?

Can't beat a stiff wall slick with a M6 car. What torque arm is you running?

Short torque arm. Tunnel mount
