Magnus Motorsport Intake Manifold = 40 HP +

[Nino Mastrocola]

Magnus Motorsports just did there back to back dyno runs on a FWD 2G talon. Keep everything the same and just switching from a 1G intake to the Magnus adjustable intake manifold made an impressive 40 HP gain at the wheels! The more modified the car, the more the HP increase you will get, especially from bigger turbos, cams, head work.

Read it here and see the dyno sheets for proof.

I wish they would make the dyno sheets readable.

i'm impressed, it sounds like a gem for FWD cars, it will decrease low end torque a little, so reduce tire spin at low end. this is what they mean by smooth out the power band

Jeremy,

I don’t know about less torque. The runners shown on in the pictures look pretty short (short runners equal less torque). From the dyno sheet the stock/new manifold numbers show more torque across the rpm range. 3000 rpm –127 ft-lb / 157 ft-lb; 3500 rpm – 194 / 201; 4000 rpm – 248 / 253; 4500 rpm – 272 / 279; 5000 rpm – 254 / 270. Don’t get me wrong, these are GREAT numbers but I’m not sure I would expect that much less torque. For us AWD guys in fact, a little more torque at lower rpm would be just what the doctor ordered, however the unit they tested looks pretty darn good as is based on the numbers.

anyone know what they are looking at charging for the intake? Looks like a nice piece especilly with the power increase.

Looks like its about $660

Can we get a diff dyno with a 20g and say 25+ psi..

it looks like the way the intake is made up with rubber.. that it would be a boost leak nightmare.. and or blowing "intake" hoses off...

turn the boost up on a bigger tubro.. and see if those rubber hoses stay on.. do the metal pipes the rubber connects to.. have beads to help seal??

just my .02$ of questions

Well I actually read the page, and they were running tentyfive psi, spiking to thirty with a stage 5 g-pumper.

As far as boost leaks, if your rubber connections between you IC piping don't leak, why would these?

then again, I don't think this is the best manifold that is going to come out by any means. Although it is cheaper than most sheetmetal intakes, and they are right about the phelonic spacer part

It was a 17C turbo.

"The test car was a 2nd generation Eagle Talon tsi FWD 1995, stock computer, Apex'i super AFC, Greddy Large front mount intercooler, 17C TDO6 8cm turbocharger w/integral wastegate, 2.5" O2 housing, Magnus stage 3 1g head consisting of port, stainless 1mm oversize valves, Titanium retainers + Dual valve springs, Mitsu Ralliart head gasket, Web 546/547 cams, 2.5 " upper IC pipe, stock bottom end, Injen intake pipe, K+N filter, 15psi of boost. No Blow off valve to eliminate the possibility of a leak."

Thank You for the correction, the stage 5 turbo car was not the same one they did the dyno with. Although it still shows that the manifold can withstand 25psi.
