Realistically the housing upgrade might not even be needed for 700whp, kept boost target at the same 31psi... Past 6600rpm you can tell there's a gradual drop, which is to keep fuel pressure consistent.

But lets keep in mind that the number is corrected, and on a relatively high reading dynojet. The DW Brushless pump is rated for 750crank hp, so that's probably around where I am at.

Let's meet up at Cryotune for a dyno run sometime.

We talked about this

I should be getting to Bandimere some time soon (probably not on decent tires though) so we can look at MPH as an indicator of 'true' power.

Yeah, but I actually would love to see a direct comparison. I had half a mind to dyno at Cryotune and Mofab in the same day. It would be cool to do it with another car or two.

I could be talked into Bandimere. I don't practice launches much though.

I'll let you know if Cryo is ever in the cards for me.

At the dragstip MPH should be a pretty good power indicator regardless of your 1/4mile time, so the launch isn't super important.

That said - I've found that high launch rpm and just dumping the clutch to make SURE it breaks a bit of traction to be ideal... Less chance of catastrophic driveline shock if the tires are spinning.

Got her to Bandimere but was having a nasty issue with a fuel cut in 1st on every run.

Best I managed was a 11.48 @ 129MPH with a 2.27 60ft - Density Altitude was about 13000ft that day

My previous 60fts were in the 1.6-1.8 range, hope to have it sorted next week.


Edit: Today on the street w/ cold tires, using a Dragy GPS, I managed an 1.98 60ft and a 1/8th mile 0.2 quicker and 2 mph faster that I did on the 1/4 mile run.

Not sure how that would translate to 1/4mile, but there's easy potential for 10's @ 130mph.

Thanks for the info, ended up buying the 0.83...yet to fit it. What size hot side and cold side pipes you running?
My plan is 2 inch from turbo to cooler and 2.5 inch from cooler to throttle. Im running a 4 inch front mount treadstone.Also running a ported 2.5 NA intake.

Yeah 129-130 will crack 10's without doing anything special driver wise. What's you launch routine? I find that for my car it likes a slight slip to engage then a dump the last 2/3's of the peddle throw from the 6,000-6,500rpm range depending on traction.

Well, the thing I've found to work with this new clutch/turbo setup is launching at ~6250, unfortunately I can't really "peddle"(pedal?) this ceramic twin disc, it's either on or off....

So for the 'best' street launch, which bettered the track launch, I set the Driving mode to S (~20psi) launch and feather the gas trying to retain traction, slap it into S# (~32psi) as the car is moving, which seems to be preventing hitting the rev limit so hard that it was fuel cutting.

It seems launching it in S#, no matter how much I try to "peddle" it, it's like hitting a brick wall.

I should be able to get back to the drag strip in about 2-3 weeks, and give that procedure a go with better grip.

I'm running an ETS FMIC with MoFab piping on the hotside.

I "think" we have the same Comp Clutch twin disk, when I said slip to engage I mean once it actually starts to engage the clutch then I just dump the rest of the way so the clutch never actually is being asked to slip, just helps with not upsetting the car in how you get to the point of engagement.

Once that all happens I let the tires spin through 1st then hit second quickly, it has gotten me extremely consistent 1.48-1.52 60' times (no slicks stock air pressure).

Be nice to see what it will do with a whole 1/4 all put together with a solid launch.

I'm actually running an XClutch now. I'll give a few different ways a try when I get to the track next! I appreciate the advice.

Oooooo Iíve been looking at those, how does the pedal feel and what is engagement like? I heard they hold some serious torque

Pedal feel is near OEM, engagement is pretty brutal and you basically have to rev it near 2500 or it'll catch so hard she stalls.

Discs are also very noisy when disengaged, but that doesn't really bother me.

Any idea what size piping that is on hot side and cold side?

I appreciate the honest input. Engagement is really that rough?(zero slip)

I really like the comp MPC I have, Organic twin disc. It engages extremely low is my only complaint, but the pedal feel is like stock and its quiet. I dont hear anything from it

I haven't taken it to Bandi to test it, but its much easier to drive than my Exedy Stage 1 HD clutch.

It's gotten a little better after driving it more - but trying to slip the clutch at all lets you to feel every 'puck' trying to aggressively engage.

Yeah my Comp Multi Disc felt like stock too.
