MAMotorsports

Sadly we switched our dyno since we have last done a C1 set, im going to try and get a car in here to do a run with and have accurate info!




Thank you for all the kind words everyone, glad we could finally make this happen!



There are a few sets in stock and more are being made, place your orders here!

I have everything ported on my intake side except the heads of course. I'm also running the Z1 intakes, but just ordered the oversized filters. I'm wondering if the restriction is the CAI or the upper, lower, or TB's. I'm seriously interested. My Wife; not so much lol

I think it's the intake. If I recall correctly, the guy with the dry sump had 3 inch intakes and a 3 inch exhaust. He also had the manifold. Maybe phunk will be done with his soon

I have already spoken with phunk about his manifold and my application as I chat with him often. He's not of the opinion that his manifold would produce any significant gains at this point. The factory manifold design is actually very good as evident by it still making power above redline with these cams. The issue is getting air into the manifold currently. Is that intake piping? It's likely a part of it. Is it TB diameter? Also likely. There's also a decent chance selective porting of the upper and perhaps lower can yield some gains as well.

I'll be working with Daelen to test once we can decide what the next step is. Personally, I'm gathering a list of options for the TBs and intake piping. It's a game of matching all the parts for a given goal for me.

Awesome sauce. You could go with a Bryant racing crank and forged internals. Bump the compression up 11:5 or something higher if you have a steady supply of E. add in some cylinder head work to support higher revs or get a bigger cam something like the jun 288??? Maybe??

derraj06

Yeah, we've talked over this engine for a long time and some of those parts are still on list of things we could try. The crank is likely to happen but there are other options currently. If all goes to plan I'll likely build a new short block with some sort of increased compression and go flex fuel for the street. That's the easy part, it is just a matter of budget and timing. The head work is a bit more tedious. As of today there are not parts to do what I want to do, similar to these C2 cams not existing. I"m stubborn and do not want to give up the VHR heads until they simply cannot do what I want to do. Lucky for me I think MA is curious enough to keep working on solutions.

As for the Jun cams, I talked to Jun about them for a while. Without a similar short block build to how they tested them, they did not recommend using them. That was surprising to me.

I am looking into if any of my friends still have some ported parts I can swap on and test. I've had a ported plenum before and it did not test well on the dyno even after being tuned for it. My guess was lack of velocity. I'd also like to get my hands on a set of larger TBs to try but I don't have anyone local to bribe into letting me swap them over and see what happens.

I've got a set of the EPS 70mm throttles combined with AAM intakes. I can tell you they do make more power.

Well what else would be ideal to have installed while the engine is out I guess is the question I meant to ask

Stock compression on the VHR is 11.0:1 --- 11.5 would not see much of a gain really. 12.5:1 Would be where I would like to go on an NA engine.



Pretty much the same package we did on Jarreds honestly.

Cams
Springs
Oil galley Gaskets
Water pump
(If mileage is high, timing components)
Oil pump


If you do not already have headers on the car, with the engine out it makes life much much easier.

great work and results. I'm definitely adding these to the list. Can't make it stretch at the moment, but I'm definitely in for future reference. Keep it up guys

Also, Derraj, PM sent

Shoot me a PM, would love to chat about the build and see if I could be of any help. We may have some options that would work for what you are looking to do.
