Can the 944 engine take 6000 RPMs?

88_944 · 88_944's Garage

I was thinking of getting a Weltmeister Performance chip that gives a 15 hp @ 6000 RPMs and I was wondering if the engine could handle the high RPMs without damaging. I think because the 944 has no rocker arms setup, 944 could take more RPMs.

I finally got an intake!

Well, stock redline is 6400rpm.
I've run mine to around 7000 a couple times (not recommending this tho).

O, I continally see that 6500 number, lots,

<-- Maniac.
No probs yet, 180,000 miles.

O, and I'd recommend the chips at www.frwilk.com big time over the weltmeister chips. And I promise you will not get 15hp.

Don't say too long above 6,500. The hydraulic lifters float and the valves hit the pistons.

Looks like a stock intake to me.

Really?

hehe it appears that the intake is stock but the filter is aftermarket to me...

Well you do have that funny looking filter on the AFS. But that is not the intake. The intake is from the throttle body to the head. Those long silver tubular things. Guess with the 944 you could include the AFS.

intake = intake manifold or the whole set up?

Of course a well maintained engine can. Its ment to go up there. Anyways take off the K&N and put the stock setup back on.

Of course, the number of times you actually use 6,000rpm are..........

Always considered the filter seperate from the intake. Works with or with out it. Even a different one than was designed for it.

most people that I talk to that installed a cone filter on their car say, "check it out, yo, i got a new intake." and I say, "no, you didn't."

Just a thought: since the cone filter has no external routing source, it is basically using hot engine bay air to feed the engine; the stock airbox, however, uses cold air from the driver's side wheel well. Wouldn't one be better off, then, with the stock air box?

One of the factory bulletins has you cutting off the intake snorkel about half way to the fender and plugging the hole in the fender well.

At 6000 rpm in spirited bursts is nothing to be concerned about....

If you will be tracking the vehicle and are planning on keeping it close to redline for sustained periods of time..... I would be more concerned about starving #2 rod bearing. This is a real issue.

Valve float can/will happen at 7000+rpm. That valve train is not designed for sustained use at that rpm. At this point you are looking at stronger springs etc....

There is a guy up here that runs his 944 Turbo on a stock head pushing over 25 psi for track use. He has yet to experience valve float........... He runs the quarter mile on this vehicle as well.... If you haven't seen a turbo at +20 psi flying past the redline on every shift ... YOu havent lived.

why? water?

ilikemy944 · 01-08-2004, 03:24 PM

yeah... lots of engines coming in for repair with hydrolock (that the right term?) water in the cylinders...

bryanthompson · bryanthompson's Garage

so... how many of us have cut the snorkel and plugged the whole, and is it worth doing? If the bulletin says to, I'd assume it's credible. If done, do you re-route the intake to somewhere where you don't get the water? Maybe putting some kind of water-deflector in the fender or something would fix that. I dunno, just wondering.

Very true

Sounds like they are advertising the max HP gain at the top of the power band. Will the motor hold togeather? Depends on the milage and how long you keep it at 6K.
