Looking for the Tuners or members on here to provide, if you have them, Dyno Results for Tomei Poncams Type R, A, B, Stock (Overlay would be perfect !) on an RB26 with N1/-7's.

- Stock or forged but not stroked

or if you have found these on the Net some where. Obviously so I can see real results on RB26 showing Torque/Power - Low/Mid/High RPM

I've read what Tomei say in regards to response of the R's being better. Seen many threads where people who know also support this. So yep it's true.

I've seen a graph overlayed against stock RB26 using stock cat muffler of the R cams and stock cams. I'd like to see A and B plotted overlay also

Tomei Published top end Horsepower achieved being very close to equivalent (1ps) on stock exhaust system for all 3 due to the airflow restrictions.

But nowhere can I find an overlay showing where the differences are.

If you can help I'd appreciate it.

I have an RB26 (Forged internals) with Type B cams and considering Type R or Stock to further improve response.

Would like to see in detail what I'm trading off. Mainly street application and considering Wakefield and Sutton Hill climb.

Cheers

Richard

Edit: GTR is well modified in all other areas

Type R or stock will define toy suit your needs Richard, it's hard to come across type r Dyno graphs as everyone just goes for type b's...

I would be very interested to see some overplayed graphs though

Unrestrictive exhaust and cat.

It's just that the only info I could find was on a stock system for the Type R cams.

I Understand Tomei made it to meet the Japanese emission/noise requirement tho I am not concerned.

Yes - Low to mid range torque response increase.

I brought my 34 with -7s and type B poncams the changed them to type Rs, made a good difference, I did have a dyno graph for the type Rs but am unsure where it is, if I can find it I'll post it up

the car made 309rwkw @ 19/20psi

I was very happy with the difference and thought it was well worth what it cost after selling the type Bs

edit, found it

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
