SilverDemon/JM Fabrications Intake Manifold Interest Thread

[aviator79]

Thats were we used to live before here back when the standback was the only tuning device. Us speed6s were doing all the work before you all came around and copied us....haha
I just linked it to show we seriously tried to get this going 4 years ago so this has been a long time coming.
Thanks to all here for all the hard work on making this happen. Sort of sucks I have no big valve head anymore, I dont know that this is even worth me getting as I will be using an uported head. I will wait and see.

How did you hear I was getting it? I thought noone knew.

It doesn't really matter where my information comes from

You mad?

dont me mad... i will take you for ride and if you Lucky I will let you drive... One rule, you break it you buy it

good to see things moving.
dturboman will you be doing a stock manifold > JM manifold comparisons on the dyno?

or just the JM manifold, wouldnt mind seeing the difference on a BT car.

[bcmurphy87]

Hopefully both so we can see true gains and not bumped up numbers to help move inventory.

[LittleredMPS]

Im just sitting back, drinking coffee to calm my nerves, and waiting patiently.

[SilverDemon]

It wouldn't be much of test if he didn't have a base line with stock mani. I am sure he will have the numbers for both the stock and the new mani.

yes doing a back to back compare of the two... at 3 boost levels

sub 20
28
35+

fight! fight! fight!

I think there are a lot of factors that will have to be considered if he shows before/after dyno numbers considering the hours of work that he put into head porting.

Flow bench numbers for each runner, stock vs. SD mani, are probably more telling, because car-to-car, there are too many variables.

If dturbo makes 500whp with stock mani ported, but 550whp with SD mani (with a tune to compensate), we won't be able to take the general assumption of a 50whp gain with this mani. Too many other variables dictate what the gain would be, and frankly if the stock IM outflows the head, what are the gains likely to be with the SD mani on a stock head, unported? Probably not significantly better than a ported stock IM.

Might be a good idea for people to consider at least port matching the head to the IM gasket to take advantage of this beast.

[SilverDemon]

This is true, but the same can be said for any part that is bolted to a car.

[Celestspeed3]

Can we get the vacuum pressure the flow benched was tested at. Industry standard is 28" of HG.

My engine builder told me some people fudge the tests to make things look better than they really are. I'm not saying the manifold is bad because I really want one. I just want to see apples to apples with the flow numbers.

[shadesofgray19]

Also should flow test the IM on a head and do the comparison that way. Making any part more efficient will see some gains but not worth the cost IMHO. JMF is doing this on a large turbo car because with more pressure pushes through some of the restrictions and will show more gains. I think the benefits over a quality ported stock mani and this on a stock turbo car will be negligible considering the costs. This mani is a big boy toy.

[trf5000]

I don't think the folks that are buying this are worried about flow fellas. Its balance of flow across runners which is key. Everyone could benefit from running this manifold.

[Celestspeed3]

Agreed.

But I want to know of the flow numbers are even across the board when subject to the highest restriction.

[06Speed6]

I think you guys are wrong, the IM should not be bolted to the head because the head flows less than the stock IM and any flow imbalance in the head could be compounded by any imbalance in the im. The IM should be tested on a sae bench at 28"h2o and there should be a radius in clay etc on both the runner and tb as per usual professional bench testing. The radius on both the JM and oem IM should be as close to identical as practical. The test should include 2 runners as a cylinder set and avg flow and % difference and % gain should be posted.

Since we all know the oem IM outflows even my ported head, flow almost isnt important. What is important is flow imbalance because on a precision tuned engine that is oem designed to run on the edge, a few % is alot.

[Downmented]

Well that about sums that up doesnt it.

[SilverDemon]

1st version flow bench run about 14% out
Runners 1 - 4
360
336
356
385

2nd version flow bench run about 5% out
Runners 1 - 4
1 - 379
2 - 356
3 - 350
4 - 379

Great improvement over the first version. Not as close to mine, but from a manufacturing standpoint this is easy to produce, and keeps the cost in check.

EDIT: All of these test were done at the industry standard 28" H2O, and on the exact same flow bench mine was tested on, with the same flow bench operator.

[bcmurphy87]

so 2 weeks till release right lol?

[SilverDemon]

Help me out here... I'm trying to figure out where I heard that before...

[dturboman]

car is on his way to Jim... we have 2 tunes to compare it to a 19psi and 28psi

All boost no nitrous.. we will also run a 35psi run and 42psi run after the manifold is installed.

FYI the final 28psi semi aggressive tune got us low 500s

[bcmurphy87]

Any updates?????????

[exentix]

Seeing this in person at the nator meat makes me want one for cosmetic purposes alone. This thing is downright sexy.

2 Weeks..

[Celestspeed3]

Pics ?

[bcmurphy87]

This has been spotted at a nator meat?

[09Speed3Z]

Spotted at a nator meat sike niggah.

This Mani would be a myth if it weren't for NATOR PA son.

Yes and my god does it look good. The whole car is a masterpiece. Do want.

The manifold on Scott's car is nowhere near the masterpiece that the finished JM manifold will be.

It is quite the sexy piece.

It was fun seeing the interaction between Scott and Jim as Scott looked over the latest prototype.

Thanks for the kind words guys!!

I talked to Jim yesterday, he has the test car, and is fitting the manifold to it as we type. The manifold fits the car quite nicely, and hope to be in the dyno very soon!!

I am soooooo sorry that I can't fabricate like Jim... I do the best with I got to work with...






















































Just messin with ya!!
