A day on the flow bench

[vwjeff]

I am OK with the results... I need power over 8k with my shitty turbo. On the same token Timmy is right and I thought it is funny how the stock ported cars and v2's trapped the same with almost idenical et's (except the Bad Bish... I HATE that car) also Trent back over the summer when he was telling me the Wilson was a joke

OH well. my manifold says Wilson on it

Thanks for testing David!!!

[celica2evo]

Oh well, I am talking to Magnus about maybe the possibility of testing the new cast manifold. I know Buschur and him have some bad blood from the past but i also saw where Dave said he would test the new one. I know pure tuning loves it. I am waiting on a reply to see if there is any way we can test it. It so, hopefully it turns out the new one is as good as people have said and maybe it will reopen one bridge for Buschur and maybe get some people off his back.

If it performs, I will be switching to that. If not, looks like ill be getting some money back and going back to the Buschur ported.

thanks for the testing. i know it feels like a wasted week to you. But it also pruves that people dont have to spend $1600 for results when your $150 works as well. I know you like to help people do it right the first time. And now you have the backing to say it works just as well.

So the hta37 sucks over 8k rpm?....

[celica2evo]

no, the 37r shines over 8k rpms. The reason it sucks is that you have to rev the car so high inorder to use that turbos power band.

[texas_gsx]

Thats what I thought, but the way he posted it was throwing me off I guess.

Anyway back to the intakes.

[David Buschur]

I've been out tonight with the wife Had a great time and am currently drunk on wine!

Yes, you are reading the results correctly. The $140 intake manifold outperformed the others up to 8,000 rpm. I guess Mike at AWDMotorsports and Al from Dynoflash were right all along. I also guess I should have tested our ported intake and TB in the beginning.

Those Mitsubishi engineers are pretty damn smart.

[yellowevo42]

Sorry if i seem confused but so this was the first time you flow benched your ported intake manifold and t/b?

[celica2evo]

Dave, just to check if you are ok with it. Shoot me a PM if youd rather do it that way.

But if I buy one of the Magnus cast manifolds, would you mind taking a day to test the V2, Magnus cast, standard ported and BR2 against each other and see how they all stack up? I am willing to do the labor for the testing if you're willing to do the dynoing and tuning.

let me know, thought it would be a chance to see how they all stack up since abunch of people are talking highly of the new Magnus and thought maybe if it performs well that people will calm down over the original manifold testing.

PM me if you want to discuss it more or let me know if you're willing to do this.

[David Buschur]

This is the first time I flow tested ANY intake manifolds for the EVO.

Brian I am fine with it. I don't really want to run all the intakes again though. If you buy one we can run it on your car against the V2 that's on it and compare it to the gains I saw with the stock ported etc. Get it and the dyno is yours for testing.

[celica2evo]

that works for me. Its going to be either the Magnus or your standard ported that goes on the car.

i just want to see how the magnus stacks up against the v2. if we find it sucks will prove abunch of people on evoM wrong, and i will have a magnus and a v2 for sale. lol

Ill get the magnus on the way at the end of next week.

Another question, what TB would you suggest running on it? I am planning on getting the stock tb flange but was wondering how you feel on that.

[David Buschur]

Yes, stock TB.

[celica2evo]

Perfect. Ill get it on its way next week. As for the testing, I have to talk to Robert about my turbo still and as soon as my turbo is 100% and the manifold is here. Ill let you know and we'll figure out a day.

[Spoolin0nYou]

Ooooweeee... I'll LMAO if the cast manifold makes less power than the V2. On the flip side, I'll eat my words if it outperforms it.

The runner length on the Magnus cast unit is about right...but I have a feeling that plenum is too big for anything less than a 42r. The CAD drawings look in line, but everybody knows that those drawings don't mean shit when the manifold is on the car.

[celica2evo]

Yea i know. pure tuning showed great results as long as the results are real. guess we will find out once its here and on the dyno. if it sucks, it sucks. Hopefully it works though. it would be nice to find something that makes the power up top without losing the mid range. guess time will tell.

[David Buschur]

I have been talking to Marco a little bit over the last few days in PM's. I'm not sure I want to test the intake the more I speak to him. I have no desire to start another shit storm. Let me see what the next few days unfold. Maybe if you buy it Brian I will have a mutual friend of ours dyno it and check the tune. That way I am not involved in it.

I'd like nothing better than to see it work really well at this point.

You can buy it but before you and I do anything let me look into this further.

I'm already catching a bunch of crap for this test.

[celica2evo]

I am talking to Keith at Pure-Tuning about maybe testing the v2 on their car that has the magnus on it. i am trying to get him to set up a time to where I can take the v2 up and be there when he dynos the 2.

The more I think about it the less i want to spend $1k on hope that it works. So I might just let Keith test the v2 and have him rev it out to 8500 or so and see how they compare.

that way if it works, I can buy it. If not Im not out a few hundred from buying it and then reselling it.

I will deep everyone updated on what is going on with that though also.

[David Buschur]

OK, I got myself thinking about which way the car was going to be faster. Unfortunately I do not have enough information to determine this. The reason is I don't know how much more the power would have climbed on the V2 and I don't know how much further it was going to fall off on the ported stocker. It pisses me off I didn't run the car out further on the testing but in the past found it wasn't need. By 8,000 rpm one intake has always showed a clear advantage or disavantage over another by then.

I think I can get a good idea though. I went over my log from the 9.04 pass. I used the time on the AEM log to come up with the date I am going to list below. Do you what you like with it but it's something else to consider.

My RS has the two step set at 6700 rpm. I started the timer as soon as the two step turned off. Then I would note the exact time the car hit 8,000 rpm and then again as soon as the RPM spiked from the shift. Then I'd start the time again as soon as the clutch engages after the shift. This is who it looked on the pass.

1st gear the car was under 8,000 rpm for 1.09 seconds
1st gear the car was over 8,000 rpm for .24 seconds

2nd gear under 8,000 rpm for 1.69 seconds
2nd gear over 8,000 rpm for .37 seconds

3rd gear under 8,000 rpm for .74 seconds
3rd gear over 8,000 rpm for .39 seconds

4th gear under 8,000 rpm for 1.93 seconds
4th gear over 8,000 rpm for 2.92 seconds

The car crosses the traps in 4th at 9570 rpm with a trap speed of 159.64 mph.

The total time spent under 8,000 rpm on the pass was 5.45 seconds
The total time spent over 8,000 rpm on the pass was 3.92 seconds.

This gives a total time of 9.37 seconds for whatever reason. The ET on the run was 9.04 I can only go by the time on the log. Kevin may have held it out past the end of the traps, I don't know. It also doesn't take into account the shifts, which I took out completely. Just stating that the time total doesn't match the ET before someone jumps my ass over it.

For me I have to consider that most of a cars ET is set in the first 330' at most. On that end of the track the car is under 8,000 rpm much more than over.

I do wonder being in 4th gear over 8,000 rpm for 2.92 seconds how that power up there effects the MPH.

Just more information.

[Spoolin0nYou]

It's very possible that Kevin held it for an additional .33 seconds after the timing beam...when you're going 150+, it's hard to gauge where the last timing beam is, so you could quite possibly stay in it for a third of a second longer.

What's the rev limiter set at?

[David Buschur]

The rev limiter is set at 9800. I set it so the car has just enough to cross the traps in 4th.

There are WAY to many guys that think they need to rev an engine to the moon to get it to work. If that's the case then they probably have built something wrong in the combination they have.

[David Buschur]

Here is the data from the runs of the three intake manifolds being run against each other. I took this from the logs. I am posting 1,000 rpm increments because this is honestly a PITA. Does anyone know how to take 3 datalogs and put the three runs over top of each other, like comparing 3 dyno charts? Is it possible? If so I'd like to take the three intakes and logs and put them over top of each other in a screen shot to post. Otherwise this is going to have to do.

It is very important to note that I did NO tuning of any type during any of this testing. As you will see the runs were so close there was no adjustment needed.
