a good read for anyone but targeted for dsm owners

As for the DSM’s. We have tried COUNTLESS tubular exhaust manifolds (headers) over the years. They made good power but the reliability SUCKS. Now if I had just welded them up and they broke that would be one thing. I have had two different certified welders do them, a company in Michigan and even Archer Racing. Archer had Borla (YES, the big ass company Borla) build them for them. They had a lifetime warranty on them. Within a year or two of them being built they stopped making/selling them, the warranties were killing them.

We will not be using a header in our kits. The reliability will suffer and it is not worth the very small increase in power.

To give you an example on the power and such. We did some flow bench testing of exhaust manifolds bolted to a 4g63 cylinder head on the flow bench. We wanted to see what the increase/decrease would be with each part bolted to the head. I did this when I was designing the header for our 4g63 tube chassis Talon that has gone 7.81 at 175 mph.

The worst flowing manifold we tested was a T3 manifold from Turbonetics. Next in line for worst was the HKS T4 manifold. The best flowing manifold we tested was a ported 2nd generation DSM manifold. After I finished building the header we put it on the same head and tested it. The numbers were INCREDIBLE. The problem is this header would never work in any production vehicle, especially FWD style. Installing this header on the head on the flow bench made the exhaust flow so much better it was like adding just over .250 to the lift of the cam!!

cliff notes:
tubular headers reliability sux to the point that borla stopped making them cuz of the warrentee, also t-series manifolds to fit dsms are a waste of time.

:cool:

it’s always been peeve of mine about the garrett series manifolds/turbos when mitsu has a far superior exhaust side even stock let alone some of the ones slowboy is selling and forced performance is making, their new exhaust side on the BB turbos is just amazing.

in short - i hate fads.

meh, wait until you get to WOW and sneak a peek under georges hood… :cool:

i know he told me and i already expressed my concern to him

yeah… his setup is pretty fucking sick. :eek2:

in the grand scheme of things i’ll keep my mouth shut about it.

no no no,i wanna hear this

you mostly have a show car, a lot of what you buy reflects this which i have no problem with and you should know that…but a sheetmetal intake and a tubular header wouldnt’ be on my list of things to buy when the 2g/evo manifold and 1g intake have been on some of the fastest cars.

dont’ get the wrong idea :stuck_out_tongue:

hahahahaha you just called brokeass a ricer

ownage= :cool:

not a ricer, i consider george a buddy of mine and it’s all quite functional…just a lot of money to spend.

id think if hes car was a “show Car” he would more than likely have his spoiler, and some insane speaker setup

george’s car looks bone stock and it fucking moves

his car is where now???:smiley:

a place where mine won’t be because of stone chips, bad exhaust tips, and flaking paint on the mirrors.

oh and as for the show comment…anyone that shines up his intercooler and complains about it getting dirty…jhaha :smiley:

Why not? Did you see the size of the turbo on his car now? George is trying to raise the bar. How is buying the best of products considered being a “showcar”?
A magnus sheetmetal intake is a nice piece and will def. outflow a 1g intake. Agreed? So he found some good deals on the stuff and decided to try it out… i dont see the problem.

I dont mean to go off here, but i would hardly call georges car a “showcar”

  • 16 inch wheels (because they are light as hell)

  • Drag radials

  • No stereo mods

  • stock interior

Basically id call it a streetcar with a nice paintjob… and whats wrong with that?

because for one the manifold is tubular which isn’t a good design on our cars because of the way it sits in the engine bay and heat disipation. as far as the intake goes, yes it’s a VERY nice intake but a little overkill on a street car you lose a lot of torque. i dunno i’m a tradionalist, if a 1g intake and head can go 10s then why put a sheetmetal one if you’re only gonna go low 12’s or 11s…it’s like buying a big gm cratemotor and running 14’s with it.

but you’re making too much of my comments.

And when you already have everything else (besides internals) pretty much done what else would you buy? sure DSM’s are capable of going that fast without these pieces, but most of those 10 sec cars are also AWD. With what he loses on the line he tries to make up in top end pull. And its not like its an all out drag racing car… also i garantee its going to be a monster on highway pulls.

well this is how i looked at it when i decided to buy this stuff.first off i upgraded the turbo to something a little on the huge side,but i wasnt planning on upgrading the exhaust mani until i came across a deal on a brand new one i just couldnt pass up.but on the intake mani,i’ve wanted one for my car for as long as i could remember,just ask kolar or jay for how long i preached about getting one.but the reasoning i wanted one was for 1.power increase that has been proven over a 1g intake mani and 2.it just looks clean.here are some dyno charts right from magnus’s site.

dyno with 1g intake mani,8.5:1 compression,GT35R ball bearing turbo(ALMOST the same turbo i have) on 17psi

now,same setup only with a magnus sheetmetal intake
http://www.magnusmotorsports.com/images/dyno/scotts_dyno_runs_06-07-03_491whp.jpg

thats a 54WHP increase by just bolting on a intake manifold.now u could look at it this way,“yea but u could do the same thing with a 1g mani” yea of course u could if u got it extrude honed,but that costs around 375-400 bucks,plus the cost of the mani,so ur looking at basically the same cost as the magnus which looks much better and is about 10lbs lighter,thing only weighs 6 lbs!

like 1320 said,i didnt realy build this thing to be a full out drag car,although at times it seems like i did.if i was worried about my torque curve i def. would have kept my 1g mani,but with me being a high powered fwd,torque is my enemy and top end is my savior(sp)

now not to bring this up but did u see my direct coil ignition setup?now that i will tell u was to clean up under the engine bay,a “show car” mod if u will.:smiley:
:smiley: :smiley: :smiley:

all I know is that georges car is goin to do better than low 12’s high 11’s
