I think you'll be somewhere between 800-825. I have a similar setup but have ID1300s.

Where are you located? I bet they squeeze a bit more out if you're up in altitude.

Any Dragy Times up there?

I made 910 RWHP with E85 and a 2.9" U/P and a 20% L/P!!!

Gotta say I love these cars without the stripes.
It just looks way meaner!

How’s the A/C doing on that 20% lower? Any issues?

No problem so far!!!

But can it outrun the local trailer park’s black GTP putting down a tire shredding 260hp with a big cam driven by a male cheerleader with a glass dildo buried in his chocolate starfish?

I'll be dynoing in the Vegas area.

I don't have a draggy but a buddy has one. I'll see if I can snag it.

Welp did 780, touch of belt slip and its safe. Stopped pull at 7450.

97 degrees on 91 oct.

Theres some more tuning I'm going to go back and do on wednesday of next week. Might be a lil more under peak. Might try 1 size smaller belt. Don't know if thats going to change anything.

It slips from 7000-7300 and starts to hook back up completely at 7350. When I go back, were going to try for 8400 rpm. FYI first pull didn't slip, follow up pulls did so seems heat in the belt/bay causes it.

Any suggestions on mitigating slip?

Do you have a Dyno graph you can post?

 

[Torchy]

Welllll I forgot to get one. I'll get one next week. We could see the slip on the log and graph.

I upgraded to the VMP 10 RIB BELT SYSTEM!!!

 

[BLK&BLUE]

I'm going to agree with the majority and say between 800-825.
Love the look of the new Apex lid!

It’ll help with trying to determine the cause. I’m trying to get my MPVI3 to data log properly… but since HPtuners released such an absolute piece of shit product… I’m still struggling to get it to complete a full data log.

After spending some time with Justin and the boys from VMP, they’re suggestion for my issue is either belt slip OR timing getting pulled at the higher RPM.

If you have a way to data log though you’ll be able to see either timing getting pulled or boost not climbing/tailing off.

Just starting to plan my mods and debating ported stock blower vs. 3.8 Whipple kit. I already have ID1300s and BAP and will stick with pump E85.
Thanks for sharing results.
How much will 325/30/20 R888Rs hook from a second gear roll?

Not sure but I’m lighting them up smashing the gas from 60mph.

Never considered the lower swap as the factory piece seems impressive but I was shooting for similar results. I’m not interested in belt slip so need to see if Whipple has that issue also.
