Okay, say I am getting a dinan sc on my 328, what other parts would I need to upgrade to handle the extra hp? I know the clutch, but what else? thanks

[knomad]

I'm interested in the response, too.

ERT said the stock clutch will handle the hp of their kit. The Dinan standard kit is rated the same or a little lower even, so I wonder if someone told you something different.

[Turbo'd325]

UR gonna need BRAKES!!!!!!!!!

[knomad]

UR gonna need brakes!


Nah. I can coast.

Actually, ERT recommended Hawk HPS pads as an upgrade.

[Turbo'd325]

How much rwhp do you have with the SC?
If its over 250hp ur going to need brakes. Stock 325 brakes weren't designed to stop a car with that much hp. You'll get maybe one good stop from say 120-50 and then your brakes are shot. I had to install brembos on my 325 after i turbo'd it. Trust me your gonna need brakes!!

[knomad]

ERT predicts 265-275 at the rear wheel. I'll have to see the dyno results to know.

I don't expect to be making any hot stops from 120 at this point. Most of my driving is in the 35-85 range.

When you put on new brakes, what did you replace? calipers? pistons? pads? A whole Brembo system?

There's no way a 325 would put out 280 at the wheel with the ERT kit. 280 is whats estimated at the crank. 232 is what's actually put out at the wheels. If you had 280 at the wheels, thats like supercharged M3 territory.

HEre's a dyno chart that they emailed me. I dont know if it will load up, but if it doesnt, email me and I will email it to you. Im going to get the RMS system for mine cause of the Vortec supercharger, and cause RMS is fairly close to me.

I agree that the numbers sound high. But we discussed it and I recall that was ERT's estimate. He thought I was probably running 170-175 at the rear wheel now with current mods and would go up to 265-270. Maybe I misunderstood something. Let me try to read that dyno chart. By the way, I'm getting a Vortech from ERT, not a Powerdyne.

[Turbo'd325]

I installed the whole brake kit: 13" 2 piece slotted rotors .4 pot calipers, and SS brake lines. This thing wants to rip out my eyes from their sockets when i brake
Anyways, 275 is great are you getting a aftercooler with ur kit? IM putting 275rwhp with a turbo so ur SC should be as fast as my car which is mad fast....Cant wait for a 3.2 block to go in but need to get some $$$$ first.
I know you will enjoy your car 100X more now, and i know that u said you wont be going to 120 my guess is that after a week you will be.lol

Turbo,
You may be right about the speed.
I am not sure about that 275 number, because people are talking me out of it. That's what I remember hearing. Anyway, it will definitely be faster than stock.
I asked ERT to do some simple work on my brakes: performance pads, SS lines, and a flush and fill with good fluid. I'll wait to see how the driving is before I decide about a whole system. Thanks for your input.

One of the issues for me is that I don't want to swap wheels. The stock wheels I'm running are 15" (I know, 15" is wimpy) and I don't know what systems are available.

[psk145]

your car will be a total sleeper though if you leave it as is. Freak the hell outta M3's making them wonder how you just smoked them!!

[540Rob]

Well your definately going to need intake and exhaust... next manifold and headers...

I don't understand the reasoning behind the brakes maybe you guys can help me out on this but if a car that weights 4000 pounds is going 60 miles an hour isn't it going to take the same amount of power to stop it if it has 200hp as it does if it has 400hp.... The brakes are stoping weight not HP. I don't know everything though.

EXACTLY!

I think everyone must be saying that one's driving style changes when one has a hotter car. The faster you go, and the more often, the more demands you place on your brakes.

[Turbo'd325]

Obviously, The faster the car the faster and harder your more inclined to drive. Im just saying that if your car gets up to speed really fast dont you think getting your car to stop equally as fast in important??? Its just my experience that the stock brakes weren't up to the task of stopping me confidently enough anymore (or not at all after a couple hard stops.) And that is why I changed mine.
Well I understand why you (knomad) are hesitant to change ur brake system b/c of ur current wheel setup. Maybe you will want to try some slotted oe size rotors and better pads, plus a high temp brake fluid which should help .

1. Ditch the stock exhaust. At least get a almost mostly open catback. The stock cats are pretty tight too. GFet rid of them if you can afford it.

2. Get the brakes. You're going to be a car-homo, up the ass of every car you get behind. Sooner or later, you'll need to drag down from speeds you aren't anticipating.

Here's why: You WILL (no, don't even try and tell me you won't) be blassting along on the freeway. Some soccer mom will have seen you with a quick glance in her mirror a ferw hundred yards back and make the mistake that you are doing under mach 1. She will then leisurely start moving her Excursion land yacht into your lane. Her quick glance will not have let her see that you are accelerating like a madman. ***You*** will be drunk with power and spanking your monkey. One thing will lead to another and you will have to scrub off 50mph in 5 car lengths. BTDT.

JSP, beautiful car man! I love it. What turbo kit do you have?

It is an awesome looking car. You can bet Jim's "Monkey" is getting spanked regularly

Have fun!

Knomad.. how long did ERT say it would take to install the SC and final tune it? That would be a huge factor as well for me..

[jsp98m3]

Mechtech. 11 psi, 407 HP.

[knomad]

JSP, That was a very funny narrative on my likely driving. Heeding the advice on this board, I have asked ERT to install stainless lines, HPS pads, and good fluid as the first upgrades to my brakes. I will look into additional work when I get the car back and see how it stops and goes.

JSP, that is the BEST looking M3 I've ever seen.

Willy, ERT said they need the car 3 days. I got an appointment scheduled for about two weeks after I called. As it turns out, they'll have my car 5 working days.
