Really? Surely blocking the only upper vent of the engine bay would increase the temp. Why do you think it wouldn't Mike? Am I missing something?

I can't wait to put the larger injectors I have in and test with E85. It's going to be a monster.

a blower car? and what size injectors

The stock airbox has the much bigger opening from your driver's side front air duct as well as the scoops from the kidney grill area to get all the air it needs.

My Dyno yesterday.
480whp and 370wtq
85 degrees and pretty humid.
Dct in 4th gear.
Afe dry filter
Bimmerworld resonated xpipe
Armytrix Exhaust
CSF dct and water radiators
93 octane.

It's a dynapak but it reads like a dynojet.
My old turbo s2000 made 550whp on this Dyno and it's able to walk FBO + tune GTRs

Do I wish it was 500whp even yes

But I am happy with the performance of the stage 1 and customer service. I will be testing on track performance in the fall. And trying to get my hands on a performancebox to measure 60-130 time.

I am talking about heat getting out of the engine bay, not air getting into the engine. Hot air rises and the only way up is the vent the is not connected to anything?

Yes but air won't be leaving through the hood vent since there is a big suction from the S/C.

CooLeh7 · 08-17-2017, 12:30 PM

One hood vent is pretty much connected to the top intake on the air box. The other hood vent is a dummy with only a small hole to drain any water. Hardly any heat would escape from these hood vents.

I have owned aftermarket and stock supercharged cars, and have driven my mates, none of them sounded anything like this.

I would expect it is in part to the lack of sound deadening on the bonnent and the likely thinner parts of the M3 and the fact it sits up high above the engine noise so it may even be amplified.

It is very very loud. Sometimes I love it, sometimes I wish I could turn it off and listen to the sweetness of the exhaust.

The power is definitely worth it though ...

It seems like it is a lot louder than I thought. Thanks for the info.

As for the noise origin, it is essentially due to the fact that it is before the throttle blades.

I've seen cars here at the forum with the hood vent covered like you said and it sure looks like it helps.
I really would like to go for a ride an a Harrop equipped M3, but I am yet to find one in SE FL.

If the noise is tolerable at cruising, this may change the whole thing. I really don't care about the noise at high RPM.

why 4th when 5th is 1 to 1?

He is DCT, 7th is 1:1, so 5th is the best one to go.

Oh I didnt know but from previous dynos I've seen in the past when they do 4th or 5th it really didnt make a difference.

But regardless of the numbers, I'll post as many real world performance numbers and situations as I can.
Might be able to get a Racelogic performancebox soon and I have a friend with a GTR with minor mods in the works

Yes, there is an intercooler core on each side, as well as a front mount heat exchanger. It's a really nice setup.

I really like this kit looks son sturdy.

You can also follow what I posted on page 11, just plug the hood vent with some foam. And there is no way this reduces the noise by 30%, id say 10-15 at best in the cabin. Not much difference to the outside world. But things may be different with a stock airbox. My metal one probably makes it worse. Or better depending on how you look at it. The noise is really part of the fun.

Patrón · 08-22-2017, 03:16 PM

wouldn't heat escape through the vents? i'd rather have them open with a little bit of noise vs trapping in exhaust heat

Whether plugged or not there won't be any exhaust heat in the airbox.

Anybody ever run the Harrop with W/M?

Ok, I think I had it wrong.

So block the vent that is hooked to the airbox, not the one that is open to thw engine bay, is that correct?

The top of the airbox, where the drivers side hood vent (on left hand drive cars) meets the airbox at the top. Both the front bumper inlet and this vent go right into the airbox and will never be subject to direct heat from the engine bay. It's open to engine bay heat if the hood is open, but not when closed.

On another note, I get my car back on Friday, it's looking fantastic. Hoping to put the larger injectors in and some E85 tuning if time permits next weekend.

What the going rate on the kits right now. I want one but know It won't be for another 8-9 months.

Then check into the going rates in about 8-9 months.
