Hello everyone

I live in the United Arab Emirates and my hellcat has upper 2.85 and lower 10% pulleys with methanol for cooling and a pcm tcm tune, doing a 19 psi boost.

In the UAE, roll racing is bigger than drag. Thats why I want to go down in the 4's 60 to 130 mpg without having to modify my engine or my supercharger.

Which one of the below would increase the timing? I dont care about HP or boost.

Bigger throttle + port blower

CAI ( i have the 717 hellcat so it has the redeye filter I believe)

Headers

Make upper pulley 2.75

Would appreciate recommending brands for the part you believe makes sense.


Thanks a lot! Happy to be part of this community!

It's impressive that you're getting a 5.1 60-130 with those mods. Must be absolutely killer DA. A fully ported supercharger will definitely get you there based on where youre already at.

4’s 60-130, your going to need spray, a 3.0 Whipple, or more cubes, or a combo of the 3 depending on heat and DA.

He says he's already at 5.1 with the mods he's listed. Hard to believe though with such little mods. That said,, what you say is definitely not true. Can be done FBO and ported blower. My car just did a 4.91 with 2.65 upper, 9% lower, ported blower, longtubes, CAI, and a drag pack on E85. This is on the street with a little bit of spin.

Nice!!! How much boost you making? Best my M6 has done is 5.8 with one shift in 2-300 DA with with equal if not more mods at 21.7 psi of boost. Under 5 seconds is a feat, good job!!

I'm not quite sure. I was right at 20psi before the ported blower and the longtubes. I imagine around 22ish. The ported blower and longtubes knocked .4 off my 60-130. DA was a little better too though. I wish I could run it in some seriously negative DA but the only time it's like that is when it's sub 40 degrees and I can't get traction. Around 60 degrees and DA in the 0-500 range is the sweet spot for me where it's making good steam but can still mange decent traction.

Only 1 run I can find now. If you factor in the slope thats 5.1

OK, it's in KM. That makes more since because that's like 62-124, not 60-130. If you were to do an actual 60-130, you'd probably be a high 5 run in the same conditions. Still a nice time though for sure.

This am on a cold bridge. 3 instruments including the car hit the times and mph pretty damn close to one another.

Was gonna say that’s really cooking but that makes more sense!

This is 2 runs made on a back road in Mexico with my Challenger Redeye. Lifted early on the 132mph pass.

 

[16GoManGoHC]

I’ve gotten closer to a 4.99 pass my self but I added a Whipple 3.0 blower. I was eating pulleys on my 2.4 so decided it was time to upgrade before grenading the IHI.

Made a 10.8 pass on the street too but my cars a stick which makes it tougher to do, each shift kills time. Would have been even faster ET and MPH but I hit rev limiter before completing the 1/4, upped it a bit for next outing. These are on the street not track with 305/35-20 Nitto 555R2 tires at 28 psi.

16GoManGoHC. I have a Whipple 3.0 and aftermarket crank, rods and pistons. I am now and plan on staying with the stock cam, heads and exhaust. I dont like noise or a rough idle.
But i love the torque.

I checked my logs for these two runs for the 60 to 130 time.
The pass that trapped 142 ran 60 to 130 at 5.33.
The 132mph pass ran 60 to 130 in 5.25

 

[16GoManGoHC]

Hi Dave!! Nice times!! Seems we’re making about the same power with the Whipple! Nice piece for sure! What pulleys you running top and bottom? You a stick too or auto? These times at the track or on the street? Their cooking as well!! 👍👍

Went out this morning and used the dragy since we finally got some good air. Was hoping for another 4.9X but I'll need to match the conditions I had when I got in the 4's. This time I had too much slope, some tire spin and 800 more DA than my best run of 4.9X.

 

[Doublewide]

Got damn good air today and got her back into the 4's. Feels good

 

[SickToo]

Dunno… torn between frame it tub it and PPF?

Maybe take it to the track and find out if you can consistently cut a good light?

See what it 60 foots?

See how consistent that # is?

See how quick it goes in the quarter or eighth mile?

See how well it repeats?

See how well it back half’s? (Saw a door slammer run 55 mph back half today!

See how much or how little weather effects your times?

See who you might meet and whatcha might learn?

It’s Kilometers not MPH.

One thing I really notice is how much supercharged cars begin to loose steam as they get closer to the 130 mark. At the 1200whp mark my 6 speed car is pretty consistent in the high 4s but it's because it starts really hauling after 100mph with Twin Turbos. I'm working on a glory run in the mid 4s at 1300whp but it's hard on the street with no prep :

 

[16GoManGoHC]

NICE!!!! Look at that DA, -761!! At 47 ft elevation Where you running across a Hudson River bridge!!!

What is your 3rd and 4th gear ratios?
What Rear ratio you running?
What for rear tires?

My best on the Draggy at 1077 wheel with the 3.0 Whipple was 5.34 in 800 DA but I’m at the edge of traction and shimmying and wiggling the whole way just about. See how spiky my G graph is compared to yours?
