Late to the party. :drama:

Jim Wolf Cam testing for the VQ37VHR -- Results inside!
 

Update. IPP is backing their work as I hoped they would and has offered to remedy the issue by paying for a local shop to do the relash.

So... all good. A bummer to have to jump through hoops but stuff happens and they are making it right so I say all good.

I’ll post new Dynos when I get them.

BTW some shops cannot reassemble the head of you take apart the VVEL system. Some can. Nissan japan can and I have spoken to one shop (maybe the only one) in the US that can but most shops can’t so BE CAREFUL before you disassemble a went-boom head for shipping as a core. PM me if you need more info about this.

Or you can just send it to MaMotorsports who came out with the product

It’s already mounted up on my motor and installed. Dropping the motor taking I all apart and shipping is a worse option.

Oh you mean in general? Yeah, that is an option.

The guys at MA have been very helpful as I go through this project.

Glad to see everything workout for you

Yup pre-corrected. You dream crusher you!! So let me down my crank estimate to 400 ish? %20 drive loss makes it 402.

Yeah, it’s almost impossible to get beyond ~330-340rwhp NA on the VQ. If you spend tremendous amounts of money and run exotic fuels, you might pick up another 10-15hp, but that hardly seems worth it. If you’re chasing HP, a Z06 or ZR1 is a good way to do it (speaking from experience)!

You have a strong forged motor with upgraded oil and fueling. Ought to be just about bomb proof on the track! :driving:

Has a Z w/Headers,free flowing exhaust,CAI & this cam been Dyno’d on a Dynojet?
By the hp claim on this 2nd grind; should put down 350-360whp easily.

I can see 350 tuned for good fuel (101OCT, E85). My car had all that, the V1 cams, and increased compression and was making 335hp tuned for 91OCT.

The record is 371whp on e85: http://www.the370z.com/engine-drivet...vhr-build.html

I've got to do some repairs and I'll take the original customer test car to Z1 in the next few weeks. Work and a wedding has kept me too busy lately to get any wrench time in.

Has any one gotten a dyno of just the gains of the C2 cams yet?

Bump for updates? Anybody else had a chance to dyno these?

The date of that build makes me wonder if VVEL was tuned; and if not, how much power was left on the table.

The guys at Z1 mentioned having a set of the C2 cams to install for a guy, but they were waiting on his FI exhaust to come in and that they would be done together. I was told that numbers would be posted, but that was the better part of 3 months ago and I haven't seen anything yet.

Exhaust hanger install was not as straight forward as I’d hoped.

Install manual looks like this, but is very misleading. For the pipes to go on right you have to have the pipes on the opposite side from shown (ie the hanger attaches to the top pipe not the bottom one) if you swap the pipes to match the picture they won’t fit around the footbox

I opted to weld (not self tap screw) the hangers on after modding them to fit the rest of the hardware

I used bits of both the old and new hanger bracket kit to fiddle together a working setup.

The lower brackets (modded to fit the new rubber shock mounts)

The new (upgraded) rubber bushings

The old (longer) upper mounts which I cut and re-welded to a better (custom?) fit on my exhaust.

As usual I put it together incorrectly 3times before finding the right fit but in my defense the instructions were very misleading. Use my photos for a better idea of how it should go! (Assuming same exhaust and coyote manifold.)

Per Jon @ Z1, the cams were done and the car made 266/231 on a baseline run. Afterwards, it made 330/260. That's with Z1 intake, HFC, ported plenum, headers, and the FI catback, plus the C2 cams.

Also, I spoke briefly with Moncef at Admin Tuning about them and he seems less than pleased.

Was anything ever established with the Jun cams with any reasonable certainty as to gains? Their less aggressive cam is the same as the JWT C2 from what I've seen. I know those are what is/was in the world record car, but last I knew, the dyno was skewed due to other changes made at the same time as the cams.

Cams are not about max hp but more about power under the curve. Without the dyno graphs before and after it is really hard to say what the gains were on that engine. We can see what happened with the car from the thread. What I would want is a flat torque curve. In a boosted car, cams are useful to help spoolup the turbo's. So, you can go with a larger turbo and exhaust housing and still have the spoolup of a small turbo while keeping the upper RPM performance where a small turbo would fall off due to a restriction in the turbine and exhaust housing. We shall see how the C2's do on a turbo setup shortly.

Quite possible Moncef can’t tune cams.

Just had my car pro tuned with AAM Intakes, HFC and catback. I have the C2 cams, just havent had time to install them. Now as far as dyno info goes i have:

-Full Stock Baseline -----------------------267HP/210tq
-Bolt on mods Baseline (no tune) --------302HP/248tq
-Pro tune after mods ----------------------326HP/260tq
-JWT C2 cams -----------------------------Pending

So hopefully soon I can get everyone some useable numbers on these cams. The tuner i went to is top notch and the VQ platform is one of his favorites/specialties. So if he cant get any more power out of these cams, i dont know if anyone can. Im still confident they will produce results though.

Any idea as to when you may have this done? I think there are equal parts hype and uncertainty around these. The more the merrier in terms of feedback.

I wasnt planning on doing them until the winter just because i dont have that much time, but seeing now the lack of data on these things im motivated to do them ASAP. I just dont know if i would be able to get a retune done soon enough. Ill e-mail him today and see whats he says.

That would be great if at all possible. I'm sure several people on here would appreciate 1 more third party test.

Who’s the tuner? Do you have aftermarket headers?

Actually, a list of any/all performance mods would be best, if you wouldn't mind.

Nothing fancy
-AAM long tubes intakes (inserts removed)
-AAM High flow cats
-AAM 2.5" catback exhaust
-ACT lightweight steel flywheel (stock original clutch, 100,000KM)
-Heavier weight Motul trans and diff oil
-Running pump gas, 94oct (dont really need 94 but it what i use)
-Z1 finned diff cover

Tuned and baselined on a DynaPack dyno by DMT just outside Toronto

Still getting 750km/tank highway even after the tune :happydance:

Being an ontario resident, who’s your tuner?

Going to be interesting considering you have oem headers,

Yah, i dont really have much faith in the aftermarket headers though, the HP to $$$ ratio doesnt make much sense. I do plan on getting a cylinder head port, larger valves one day, and once that happens i doubt ill put the OEM headers back on. Unless im really broke!!! :ughdance:

Ma recommends long tubes or some type of header with the c2 cams to get the full benefits. Porting the heads on a stock short block isn’t going to yield you that much power. Seems like a waste if you referring to Hp to $$$ ratio. You’re better if porting the upper and getting a set of long tubes.

Blue line C1 cams
Red line C2 cams

Pretty good comparison as mostly same build on both pulls.
(Red pull was on block with proper pistons, blue pull had rattly, slightly too small pistons hence the rebuild with the C2s)

Similar hp
Slightly better low end torque with C2s

Do you have test pipes, stock cats, HF cats, or long tube headers?

Edit;

Z1 400 hp kit, and Stillen g3 long tube intakes, Berk CBE.

Also,(but likely unrelated) z1 built short block, ATI harmonic balancer, jet hot ceramic coated from headers to test pipes. Nismo oil pump. Uprev tune. Z1 lightweight clutch/flywheel (6mt) billet CSC. Z1 vented rotors... I think that’s all the stuff that might effect hp/ torque numbers, and none of changed between cam swaps except for tightening the clearances between pistons and cylinders a few thousandths.

fyi the Z1 kit uses shorty headers not long tubes.

I think the long tube refers to the G3 intake

my brain registered the previous question being about headers and didnt realize he answered about intakes :bowrofl:

stillen does have a set of headers that are pretty much the exact shape/setup as the Z1 shorty headers. maybe thats why i went that way as well.

Correct

Maybe I missed it but has anyone done a before and after with the v1 or v2 cams on a turbo Z?

Mine is done now I just have to replace injectors to finish up tuning. It'll be kinda hard to compare it to anything because I'm running this with a 6870 turbo on a BP kit and 10:1 compression where most people go 9:1 .
