530whp saw 45whp peak on my car and I have replicated the exact same results on 3 others so I feel there is definitely power to be made. We went into this thinking that you can only get so perfect before you build a manifold to focus on one specific region (i.e. 3000-6000 or 6000-9000). power past 6500 is still power past 6500 though and the 30-45whp is in the range most drag racers can use it independent of setup. My working powerband in my car is 5700-8600, so anything past 6500 is going to make a huge difference to me. On my car now, I would presume I would lose 50whp easily if I went back to a stock manifold.

i did not say i did not make power. i just said it was garbage. i thought dave tested it. or at least had one he was going to test. a manifold like DI,BR,AMS,MAGNUS and stock ported unitsdo not need modding for install. thats what i meant. no reason you should have to do more work to it to make it fit.

 

I agree, on a bigger HP car taking off a good intake is going to be worth more than 30 whp as stated by 03white.

Hell on a 600 whp build just porting the stock intake has proven to be worth 30 whp.

There is no perfect intake for a 2.0, 2.1, 2.3 and 2.4. Each seems to require a little something different. These huge plenums are best suited for 2.3/2.4's though and SUCK on a 2 liter.

 

I have been thinking for a while about upgrading my ported stocker on my 2.4 but I will only do this if I dont lose too much torque and response. I know I will make more hp up top for sure but not willing to trade off the response. Would be interesting to see the buschur ported against the magnus or AMS units on a 2.4.

 

Not trying to fight here, but you saw that I said over a PORTED stocker, right? To make more than 30 HP over a ported stocker would mean 60 HP over an unported stocker based on your opinion which I don’t think happens on most setups?

I get this from all the dyno charts you and others posted seeming to show only like 20-30 HP over the stocker on average with big gains being in the 40-50 range. Then the typical ported stocker seems to be good for 20HP and 30+ on big gain cars… That means 0-30 is about the power gain range you see over a ported stocker with all these intakes.

I have no doubt a well setup car can make good use of the 30 extra HP. Just pointing out that A LOT Of cars out there run around with every power mod made and then try to drag race on 300 tread life all seasons.

Just pointing out the ironic nature of hunting for that 10 HP difference that people seem to be infatuated with when there are much more significant gains to be had with other parts.

 

I agree completely. Intake manifold choice and design is very combination dependent. On a 2.0L you can lose a bunch of torque with the wrong intake down low for the amount you pick up out the top. Even then, some just really focus the gains out the top and leave some stuff relatively alone down low.

I can see a motor that made 600whp mustang (around 680 on our DJ) picking up 30whp from a ported stocker. We have test this on a car that made 636whp on our dyno and found 21whp with no other changes and it was something of a rough port in comparison to some stock manifolds port jobs. Altered plenum size and shortening the effective length of the runner had more to do with that than anything. I think swapping that particular car over to a Magnus would have seen even more gains.

Sorry 03white, I didn't see you say ported stocker.

 

No problem. Kind of surprised me as it seems like you like the ported stocker for many setups because it's inexpensive and works.

Can't argue with those results.

For somebody pushin the limits on a given turbo, I'm sure that extra 30HP or so is worth the money.

 

I will never trade 30 whp of PEAK power for a fatter area under the curve, unless I'm wasting my time building an all out drag car.

 

Your car shows what is possible when you spend the time to maximize power band and not just peak numbers.

Sacrificing "only a 100 RPM" here and "just 200 RPM" there on boost response can quickly lead to 1000 RPM overall. I know that's how I ended up with a laggy 16g setup...

 

I agree Dave. It makes me wonder Which maifold would be best suited for people like me on the stock block who DD, autox, and do he occasional track day. I would assume your ported stocker or MAPs rev 3 would be best. But then you sees R/T Ernie through the Magnus on with his HKS turbo and it still spools fast than stock. Who knows anymore with all of these great products guys! And great testing!

 

I'll get hammered for this but..... I don't think using a Dynojet for testing power under the curve is very good, take a look at Curts curve on a Dynojet and then on our MD. The MD loads the car very close to the street and when you are trying to dyno test a part across the curve I feel that loading is crucial.

 

Not hammered from us but I am sure you agree that some of that is operator. We have load control and 5k worth of roller weight to load the car with so we can get a pretty good feel. I can run in 4th and lose power and pick up torque (and triple the pull time).

 

Dyno for dyno... especially using the same dyno...same gear... my HKS/Magnus v5 setup does spool up faster than stock. Proven by boost pressure logs and the dyno charts. A dyno is a tool afterall. Good discussion guys.

Thank you everyone for being civil.

 

Wow very odd the AMS lost power after things were fixed on the car... But then again different day etc so that could account for the lose.

All i know for a fact is that my F1I works VERY well on my 2 liter with my setup! And i 110% agree there is no perfect intake for every application.. And not just displacement of the engine but cams being used etc... The list goes on and on.
