WHAT, you guys should be testing this on nitromethane. Then we can get some outstanding numbers.

Aras should...he has the engine management to run it. I, on the other hand, do not. Also, he is a full custom build with pretty much nothing stock.

I am dyno'ing on 93 octane because I committed to being the guinea pig for the gude head/cams for the rest of you guys, and everyone (pretty much) has access to 93 on here. Therefor, if I say I went from a base of 101hp to 112hp with the head/cams/93 octane, you have something more realistic to work with than if I said I was running 107 and put down 120hp.

I thought about it though....will probably run 103 after I get all the supporting parts that are filling my living room installed, but I've been waiting on this dyno to fulfill my commitment.

Here are some pics of my head work from Gude

Tomorrow is a big day, you're both going to the dyno.. CANT WAIT!!

I don't mean to be a dick but those cams look odd like the lobes are cast rather than machined. It might just be the picture but the lobes look like they are cast and rough.

Their regrinds. All is well with the machining. They do have a molly coat on them.

Yes tommorow, I'm headed to CFT. Got some wiring to do when we first get there but should be on the dyno by mid-week.

Time to see some results.

We were testing the car with JUST the head and cams...no other modifications or bolt-ons. Power went from 98.93 to 104.10 (5.2% gain) on stock fuel maps. Torque dropped from 100.55 to 95.33 (5.4% loss). Using the CamCon to tune, we were able to get power to 108.43 (9.6% over stock) and tq to 98.78 (1.8% total loss). Most exciting thing to note is the lack of high rpm drop off associated with stock config. Again, this was on stock airbox/intake and exhaust and a dirty air filter so, while I had hoped to get to 110, I'm curious to see how this does after intake/exhaust, as the head could literally be being choked by stock system. We will see though.

Red - head/cams + camcon
Blue - head/cams on stock maps

Its interesting how cams seem lose Tq on this motor. Ours are a more mild grind than yours, SCCA Production class rules limit us to .390 lift and only port matching 1" in, but like you we also lost some bottom end.

Wait till you get real engine management, when you can start to spin it past 6500rpm it will really sing and you will see the payoff.

I'm looking forward to it...You really start to feel the cams....and then you crash into the rev limiter. So disappointing. Trying to decide now between being the test dummy for the dezod unit, or just going full standalone and being done with it. What are you running?

AEM EMS series 2 with a custom plug and play harness by MP Tuning. The OE computer is still in place to control the DBW, with the AEM running the rest - including the VVTi.

If we did not have to use the stock TB and manifold (the SCCA Prod rules require the OE setup) I would ditch the stock ECU and use an xB or custom intake setup.

I wonder if you can pair the Dezod unit with the Camcon to essentially get the same control we have? As I understand it the Dezod unit does not offer VVTi control(?) The Camcon is limited to 500rpm steps, but it might make a good budget setup.

[H3LlIoN]

I too was wondering if they could be piggybacked, since you are correct. No vvt-i w/ dezod. Too bad they require the stock tb. Are you allowed to bore it?

No, its 100% stock. That is how they balance a class with 40 year old British cars and new cars.

Well guys the XB is at CFT getting the T/B wired into the Microtech and some other misc. Nitrous wiring done. The car should be ready to tune by end of week.

I know my cams are a little more wilder than yours and will have no way to test mine stock because of my standalone and all my mods but well she what she produces soon.

Keep in mind I did away with the VVTI which is also why my cam grind is full race as well as microtech only allows me to turn on vvti which makes it more like vvt.

I wanted a more race old school set-up. I know I got alot going on under the hood and will not be able to tell you what does the trick but I will assume it's a combination of all my stuff being Big and built strong.

70mm T/B
3" pipe
680cc injectors
big turbo
Crazy cams
Full stand-alone

All I know, is this better do something good.

Will post new complete engine bay pics in an hour or so.

With a turbo I don't think I would worry about the few trivial HP/TQ lost from not having VVTi.

[xbgod]

I was thinking like you were. Though it will still interesting to see what happens,
