On that note, anyone have a spare Varioram intake setup lying around that they'd sell? Normal or RS variants considered... PM me.

Thinking out of the box here. I haven't seen Ken post much but he does have a SW built motor from that faux RS. Will he be willing to part with that motor at a decent price and you will have to remap the ecu to accommodate for Emissions. Timeline is fast and local to you. Motor is basically plug and play

In addition to torque/HP gains with Varioram, the sound is intoxicating

I just installed a Varioarm intake in my 95. The difference is noticeable.

Was the sound different too? I've never heard that detail before.

myflat6

^ yes, you can hear the Varioram do its thing through the RPM's. I have the motorsound air box cover, so maybe this enhances the sound, but you can clearly hear the Varioram adjustments around 5k RPM and again around 6k RPM when you are hard on the throttle.

Tlaloc75

That's cool. I have motorsound as well and I love the unique noises that come from my car's butt. Don't have a 95 to compare to, so not sure which sounds are unique to varioram. I imagine intake noise would be different and it certainly sounds different than my 92 used to.

The sounds that differentiate the non- from the varioram are due to the intake runner tubes lengthening at around 3500 rpm (well thats where its set at on my car). The non- car does not have these tubes that lengthen the intake runners, but both intakes have the resonance flap and thats why at higher rpms, the non- and varioram cars dont show much difference in torque.

Actually, they DO have a significant difference in torque,....

Its about 25-30 lbs-ft and thats significant.

Factory settings have the stacks shortening at 5250 and the resonance flap opening shortly after that.

You can really see the difference on a dyno plot overlay between the two engines.

Those values seem a little high, "...if you take a 993 and add cams and valves you are at 325."

SwayBar

And according to that chart, by adding a free-flow exhaust and tune on a VRAM 3.6, one has virtually the same hp, and more torque than a factory stock 3.8.

Infinitely better bang for the buck going that route!

Steve Weiner-Rennsport Systems

OMG, yes.

The engine dyno shows very different results.

AZ Targa

Thanks Steve, I was looking at that and wondering where I went wrong...

MarinS4

The added displacement is always welcome but I would spend my money elsewhere. Hotter RS cams and bumping the compression by shaving heads/cylinders would make for a perky motor. I would also retro fit cam gears for more precise cam timing. This is not to be over looked! As mentioned earlier VRAM is really a nice feature. It's the best thing we have going to flatten the torque of a 2 valve non VVT motor.

Do all that and then add turbos if you really want to be a ballar!

JPS

If I thought the turbo option could last factory MTBF (ish) and withstand track duty, I'd do the ProtoMotive Stage 2 (500+ HP). But I just don't see it lasting like that off the street.

"retro for cam gears"?
