sexyyyy, so how much would all that set me back if i was wanting to do that?

 

can you show the boost curve in greater detail?

think the cams are hurting spool any?

 

Yes I can, but when I plot it that way, dual axis, all the max #'s overlap on top of eachother and made them hard to read so I did it that way

I like the 650+ horspower all the way from 4700 to 7700 RPM

Yeah, she's a screamer. At 18psi and 116 octane and even lower time map she was doing 555AWHP 496AWTQ

Wait, since when do you guys make 3.5 pistons? Ross has a 6 week back order, can you guys get them faster?

These are NOT off he shelf 3.5 pistons, when I did the math using combustion CC, stroke, bore, head gasket thickness, Ross off the shelf 3.5s were almost 10:1. So we had these special made 8.5. Working out great. We can get you a set faster than 6 weeks.

Thats what I was going to say.

Give Josh a ring at 704-786-6400
He'll get you setup.

got a boost curve for your daily and this 3.5 to compare spool?

 

Dam, Chris that's some sick sh*t.

 

Nice.

I wants.

 

no video of that car? i love to see it doing some street pulls and some racing.

 

Well, It's a customer's car, so maybe a dyno vid but no street racing. That I will leave up to him.

-Chris

 

Awesome. Great numbers. :bigthumb:

Scotty

 

Just how conservative is your pump fuel tune?

Jason

 

I think the race gas tune I am topping out at 16 deg at 8K @ 28psi. Not 100% on that, too many race gas fumes today, and a little ethanol from another project I am working on. Long day.

Can't remember what numbers I am at on pump, and obviously not 28psi LOL.

-Chris

 

not bad Chris

 

Very impressive

 

Hell yeah that's awesome, the dropping off of the power curve is weird though, I would lurve to do twin sequential on a small V8 one day...just for two kicks in the pants.

 

The area under that HP curve is really fantastic. That car must be a blast to drive.

 

I want a 3.5, thats good stuff.

 

Oh Snap! That poewr curve looks great. 1000cc injectors I'm guessing?

Damn I gotta finish my build.

 

Well, 1600cc

Be right back...It's E85 time....

-Chris

 

Did two back up runs this morning to get vids. Last one was 733AWTQ 720AWHP.
Will post video later, maybe this weekend.

-Chris

 

Dont use it all up, leave some for the customer too!

 

that curve makes it look like that car is not even trying, that would feel insane on the street. why does the tq fall off so fast after peaking? i would think with heads and cams peak tq would occur a little farther out and last a little longer.

 

How extreme are those heads?
Is it the heads or the cams plugging up? Or something else.
What manifolds do you guys use with the 5027's?

the 3.5L probably makes restrictions a lot more obvious because it spools big turbos sooner then other gas powered setups. Maybe if you unplug this car, you might find power in 3.0's that was harder to locate before

 

The powerband looks awfully peaky for a 3.5L to me. Still good numbers in the end though.

Heres Matt M's DR1200 chart with his 3.45L using a ARC2 for comparison.

Jason

 

Looks like a 4th gear pull? And DR1200s are a different turbo.

What are the RPMs on that chart?

-Chris

 

He broke 800tq before 4500rpm.

Matt is making 900hp 626ft/lb @ 7550 rpms
Matt is making 950hp 907ft/lb @ 5500 rpms
Matt is making 700hp 813ft/lb @ 4500 rpms

I guess the TD05 based turbo setup chokes the bigger 3.5L down low(which doesnt make much of any sense)? Something doesnt add up, as Matt was running bigger turbos and a draw through MAS.

Jason

 

They aren't TD05

-Chris

 

Also curious as to what header/turbo's are on there. Sounds like a killer setup.

 

Is the customer willing to swap out cams or install adjustable cam gears to improve the power beyond 5000 rpm? Very nice.

 

I was implying the turbo setup is TD05 based, i assume you are using your TD05 manifolds and a TD05 framed hot-side on the turbos?

I am not questioning the numbers, but i am wondering, out of curiousity not to take a jab at your tuning ability of 3sx in any way, why your car with essentially the same sized engine, smaller turbos and tuned on an EMS doesnt have nearly as smooth or broad of a powerband as Matts. That is all.
