Any updates from Denchan350gt or the OP? How did the members cars end up and what's the status on a stage 2?

These results are becoming rare just like the tommy K shift knobs

I'll have a dyno soon and will post up results then. It won't be apples-to-apples as I have a modified block, but a data point nonetheless.

stage 2 should be here within next few weeks

Nice, can't wait for someone to slap them into a car that has all the bolt-ons already. If someone would make some progress on an intake manifold also, things could get very interesting.

Yeah i hear you on the manifold, but from what I've been told our manifolds flow pretty well. Bullet is suppose to have these cams in soon along with a bryant racing billet crank and whatever goodies and revving to 9K. I'm still 9 months away from testing these cams out, but i'll only be revving to 8200-8300 rpms with the nismo oil pump along with ported heads and some other goodies.

I have all the usual bolt-ons and am wondering what these cams along with maybe ported TBs, and upper/lower manifolds will do to a car that already has everythign else.

Interesting

Cams are in the motor just have to swap the engines. Going to be a delay I heard rumors that the S2's are coming out soon and are in the testing phase.

Waiting on the results of those. JWT said the price will be the same, will benefit both NA and FI, and I can use the same springs from the S1's. No word on duration or lift. My motor is still on the engine stand so it will be easy to swap them out.

I will keep everyone posted.

Hopefully we will find out in a few weeks just waiting on the stg 2 results.

I have ported upper and lowers
70mm TBs
3in intakes
Aluminum driveshaft (I have a G37) 370's are CF stock.

Before the cams and the mods above car put down 320/260 on a dynojet.

Where did you get the 70mm TBs and intake? Do you have headers installed already?

Prob Jake and Mosef, eps and admin.

I got the TBs from EPS tuning had them for about a year.

3in intakes my friend at RZG is making for me. I will have a set of AAM 2.75 intakes for sale soon.

My upper and lower was ported by Synolimit

No headers yet I'm waiting to see what the Motordyne LTH produce. Wish they were out while the motor is still on the stand.

So many rumors lol



We have been working closely with JWT on both the C1 and C2s for the VHR engines. We will have the first few sets to test, and I will post results the same way I did with the C1s.

The multiple cars we have with C1s, including the initial prototype set are off and running well with zero complaints still.


To dispel some of the rumors, final specs have just recently been decided for the C2s, they have not been released to anyone. So if someone told you some, they are most likely just making them up, or got a vague answer from JWT and took it their own way.

The prototype sets will be to be in my hands between 50-80 days from today. I have already lined up 2 cars that will be in the shop for testing, an NA car that is fairly stock with basic bolt on's (We will also be doing a set of long tubes after the initial test to see the changes, as that will really make the cams shine) and a turbo car we are building in house(Built motor, Fast Intentions Stage 3 kit). There are 1-2 sets that we may also send out for external testing but that is honestly undecided at this point, as we dont really want to send out an un-tested part but we will see.



If anyone has any specific questions, you can PM me or post here, I will answer to the best of my knowledge as much as I can.

I wasn't told any specs figured they wouldn't tell me anyway if I asked. Only posted what I was told by JWT when I called yesterday nothing was made up.

I have the C1's in my motor now waiting to install don't want to install the motor if the C2's are better NA than the C1's (not going FI).

Which was why I asked JWT if they were better suited for NA or FI he told me they work with both.

JWT said if I can wait on my motor install which I can to see what the results show in a few weeks. I'm just giving a status on my build.

None of that was aimed at you directly, I just wanted to clear the air as I keep getting calls from people with very false info on these. I just dont want people to be miss informed or waiting on a product for a few weeks, when in all honestly it will be a few months.


Also, unless you have long tubes the C2s are not going to work as well as they should. With a larger cam like this the engine will really need to breathe.

[QUOTE=denchan350gt;3501830]I got the TBs from EPS tuning had them for about a year.

3in intakes my friend at RZG is making for me. I will have a set of AAM 2.75 intakes for sale soon.

What do these 3" intakes look like? Are they designed like the AAM intakes, just with a thicker pipe? Are the 70" TBs made to fit 3"?

Based on rules for TT at my current weight I need 16 more HP. I'd love cams but idk what to do at this point. I've tried E85 on uprev and lost 12hp. $800 for ecutek doesn't sound appetizing. Uprev claims huge release soon but I doubt a tune/timing/fuel etc will net 10hp. Only cheap thing I could try is maybe bigger TB's and go back to larger intakes. Other than that I'd love a cam that should produce a result unlike keeping my fingers crossed on a tuning package.

If I could pick up 40who/40wtrq from Larger TBs, larger intake piping, ported upper/lower manis and the Cams for about $5500 all in (including labor and tune) without it sounding bad (the 'lobe lobe lobe' sound I've heard from some other cams), I am probably in. I know that's asking a lot, but that's what it would take for this investment to be worthwhile to me at this point. Any knowledgeable people think that is reasonable or possible?

These are my hopes/expectations for gains

Stage 2 cams - 20whp, 35wtrq (seems like a lot, but they're saying the stage 1s gained 30 so...)
Ported upper/lower mani - 7whp
70mm TBs - 6 whp
Larger CAI piping - 4 whp
bump (top end) from losing the m370 - 5 whp
Trq from combination of piping, TBs, upper/lower manis - 10 wtrq

total - 42 whp, 45 wtrq
end result - 350+whp, 310 wtrq for under 6k

Is this a pipe dream?

Would you could run into a flow issue? I'm be interested in those results with that set up. I"m halfway into my savings for the big NA build.

I have no idea. I am waiting for people who know better than me to figure it out. Waiting for updates from people who do these mods.

These numbers do not seem like a pipe dream to me, but the variance from brand to brand for each part will have to be taken into account. As one brand may loose power, one may make power. Only testing will tell. Even more so with every car being a little bit different, and people being in different locations, different dynos, etc. The number on the dyno is not always the full story.


One big thing I see missing on your list is headers, its in my belief that to take full advantage of the upcoming C2s a set of long tubes will be a big step forward. Even more so if you are on the hunt for torque.


-Daelen

I know we have spoken before about the issues you have had, I would honestly say the jump to ECUtek may be the best bet with all the problems you have had on UpRev. Start with that, and see where it takes you, although I think cams will help it sounds to me like other issues need to be sorted first.



-Daelen

I already have headers

Perfect

My engine is done and the cams are in. Car's on the dyno, ready for break-in. Won't be long now...

What other mods do you have? Are you doing everything at once or adding cams to existing breather mods?

F.I. LTH, Stillen Gen 3, engine is from Rebello Racing (VQ37VHR, 11.5:1 compression, JE Pistons/K1 Rods). Also have 3.9 final drive gears with an OSG LSD. EcuTek tuned. Haven't decided on catback yet. It's being done all at once. Previously, I was doing 286 rwhp with EcuTek on 91 with an otherwise stock car. Will be interesting to see what it does!

OOOOO interesting. You getting tuned on 91 octane? will the dyno number be a little skewed because of the 3.9 gears ( this is for all the people who care about numbers).

What where your previous torque numbers? Because that's the real star of these cams.

Oh man, cant wait to see these results.

240 lb/ft. Here's the old chart:

http://www.the370z.com/members-370z-...ml#post3333164

that was more or less stock (not counting suspension etc.)? The new one is going to have LTHs, cams, and intake? Nothing else?

Tuned for 91, but it's aggressive. On the track, I run 101, and I have a six-pack of Race Gas additive for the rare cases where I can't get 101 (like Auto Club Speedway). Definitely want to make sure I don't have to buy a fourth (!) motor.

Yep, all stock except for suspension and oil cooler. The new one will have all that, and higher compression (11.5:1) and a new exhaust to mate up to the LTHs -- haven't decided which one yet, I'd like to get the F.I. one, but it takes too long to make.

Also, the 3.9 final drive will skew the new dyno numbers a bit.

Any idea when you'll have her on the dyno for a tune? Were the pistons expensive? I wonder how much of a difference the higher compression makes.

I don't have a cost breakdown for the individual engine parts, but the whole thing was $6400. The main goal is to create a highly reliable track-oriented build. Hence it also has the CJM oil pan, road race pump, and eventually I'll add the RJM oil pump gears.

It's on the dyno now for break-in, so I'll have numbers soon, probably next week. Starting from my previous EcuTek tune, we had to adjust the throttle table down a bit because it was too twitchy with all the extra torque.

I'm assuming you have the stage 1 cams How does the engine sound? Is there that 'lobe lobe lobe' noise some cars with cams have? a video with audio when it's all done would be great if possible.

Stage 1, yes. It definitely has a different character to it, I'll post up a video along with a full write up about the build soon.

'lobe lobe lobe'

I've heard lumpy idles called many things, but never that!
