CJ Motorsports VHR Intake Manifold

Nismo350z#310

I somehow missed this, but just read it.

So looks like us HR guys will have a bolt-on part too!!! This excites me greatly!

So this will be designed to suit HR heads as well as VHR heads on VQ37 block ??

It doesn't technically matter which heads you have, but which lower intake manifold you have. but I do doubt HR rails would clear the VHR heads if you tried to use a HR LIM on VHR heads.

Can't wait to see the cast product! Hopefully the price in the end is reasonable and not ridiculous like previous attempts by other company's. Think that was one of the major killers in the past. I so want one lol

It wont be cheap... but it wont be insane either. We try to keep things reasonable and fair. We will have a lot invested in this by the time it is completed. Its not like a sheet metal manifold where the only investment is in having some flanges water cut and then welding up tubes.

We are casting the main part, which will be very expensive in custom cast tooling. From there we will make the plenum lids in either billet or sheet metal and perhaps down the road we can have some conversations about CF since we know a guy for that.

When the project is much closer and locked in, we will be able to gauge interest and that will have a huge factor on pricing. If we only sold 10 of them and the cost of tooling and design has to be divided up between only 10... they will be expensive as heck. But if we find that more like 30+ people are really interested than suddenly the development costs divided up starts to get pretty low.

Intake manifold projects are a little scary. Its not like a turbo kit where no matter what you do its going to make huge power and everyone has a great time arguing about negligible differences in powerband from one kit to another.

For an all-motor application, an intake manifold will either lose or make power in differing engine speed ranges, or if you really screw up it will lose power everywhere... and there is no boost controller to save you. You are pretty far in development before you really get to find out for sure on a dyno... and in the case of the aftermarket economics with the 370z, it might be too late to change things much by then.

This manifold will be a great manifold for boosted cars. But for all-motor... that is very hard to make promises until its on the dyno (since the stock unit does perform well afterall). If it loses power on all-motor cars, its not going to sell like crazy. If it doesnt lose any power on NA, it will sell non-stop just because the stock part is ugly. If it *gains* power NA, we wont be able to keep them on the shelves and the price will be much more affordable. So lets all cross our fingers it works well! The better it performs, the cheaper it will be!

Now only if all manufacturers in the world would be so open and honest like Charles!

You are so right lol. Honesty in the market place is so important and makes people truly appreciate that specific vendor even more. Charles, I was wondering is anyone from Cj motorsports attending zdayz this year?

Any updates on this manifold?

phunk

Thanks for the kind words guys. Busy season hit me earlier than usual this year but this project is still a front runner. I just keep getting pulled every which way lately.

My target is to get this released this coming spring, and I do not see anything yet that is going to prevent that. But I will have more details from the pattern builder next week I expect as he is reviewing whatever it is he needs to review while making his plan.

Making adjustments to the CAD right now so that I can start cutting it perhaps next weekend.

Ditching the casting... going full billet. This means some adjustment to the design to accommodate an alternate manufacturing method from originally intended. I just dont want to deal with the delays and control issues with casting. Too many friends in the industry having too many problems and delays dealing with casting... some having bailed out after investing several thousands. I will go full billet for now, and if its a success maybe then I will work on a refined casting.

Well Charles, the longer we wait the more I think your feeding off my idea of a reveal at zdayz. Sceaming in the dark till the day comes and you go, "oh hey by the way look what we did!" Hahaha.
