3.6 Vram dyno run - Kermie's new engine

[skinnerd]

Over the winter, I've been refurbishing much of my car....freshening it up from the many years of autocrossing and track abuse.
Besides some bodywork and paint, I decided to treat myself to a new drivetrain (gearbox and engine).

Out with the old:

A 3.2 Motronic that was slightly modded (sport cams, larger throttle body, SSI's, sport exhaust, Steve Wong chip.
HP? Possibly around 225-230.

Last fall I attempted to locate a good, used, low mileage Varioram engine for my soon to be RSR looking beastie.
After many months, I gave up in frustration.
With all the time, effort and money being put into the rest of the car, I decided the powerplant needed to be equally as "killer."

I gave Rothsport the go-ahead in late December to build me a fresh Varioram engine.
They took a core engine they had on hand, and built me 3.6 RS Varioram.
In went RS cams and the larger RS intake valves, racing valve springs w/ Ti retainers.
993 heat exchangers (for defrost) and 3 outlet rally style M&K exhaust.
Custom DME programming, the works.
Freshly powder coated engine tins.
Everything mic'd, inspected, replaced, rebuilt, renewed, etc, etc.
In the end, the engine looks brand new....and in reality is.

Here are some pics in the dyno room:






Happy camper!

Guess I should post the dyno run and results too?


Unfortunately my 33MB clip of the dyno pull can't be posted here.
I'll try to host it somewhere else with a link here later.

But the bottomline, end result was fantastic.
See dyno graph below.
310 hp and 271 torque peak readings with a very flat torque curve.



Can't wait to get this engine and my new gearbox installed.
Hauling it down to TRE's shop in the next couple weeks to mate back up with Kermie.....or should I say Godzilla now?
With a purposeful grimace and a terrible sound
He pulls the spitting high tension wires down, Godzilla!

A Big Congrats!! Enjoy in good health.

Very cool Skinnerd. Is that RWHP?

[skinnerd]

No.....should be at the flywheel seeing as it was measured on an engine dyno.

Geez, my bad!!
With 15% loss you'll get about what I have, 274 rwhp. She'll friggin' fly. You'll be amazed.

[skinnerd]

Hope so.....the car weighs about 2300 lbs.

[Buckterrier]

Wow Doug you'll have an awesome car. Mine weighs in at 2640 with 1/3 tank of petrol.
Great color. I have the same torque number also.

[skinnerd]

The fresh Euro 915 with SCRS gearing, 40/80 Guard LSD, ext cooler, spray bar and Wevo bearing retainer inserts.... should get it moving down the road in fine fashion.

[Buckterrier]

I take it Kermie is an all out track car? What exhaust will you be going with?

[skinnerd]

Actually no....
Street legal. Capable of rallies, autocrosses, and track events.
This car used to do PCA club racing, but is retired from that now.
Spending the winter making it more comfortable.....yet faster.
Makes sense?

The exhaust I'm trying is a custom M&K R style with different inlets to mate up with the 993 HE's and a 3rd outlet (all 3 outlets cap-able), so hopefully I can cap the two rear facing outlets for slightly less noise in town.

[HarryD]

So, are you going to give Britian a run for his money?

[Bill Verburg]

Very nice!

[Buckterrier]

I also have an M&K with 993 HE, good power.

[slow&rusty]

Wow..beautiful and awesome that car is going to scoooot!

Nice job! That's a project I thought about myself. Then came baby Emma... Congrads!

[skinnerd]

Car has come a long way since late Sept when I dropped it off at TRE's shop.
Kundensport has done the body work and paint already.....beautiful job.

Went from this:

Last time I saw in it early January, it was at this stage:


Since then, the car has moved from Kundensport's shop back to TRE Motorsports where there are putting the rest of the car together.

Ultimately, Kermie should look a lot like this car (without the uber expensive 15" Fuchs for the time.....my Fiskes will just have to do)


Interior will all be new....headliner, lightweight carpeting, nice covering over my existing rollbar, new old style Scheel seats like these:


and 74 RSR inspired steering wheel:




Hopefully in the end this will be very fast, but comfortable vintage looking hot rod.
Capable of holding it's own on the track or auto-x course.

About 4-6 weeks until it hits the road.
Won't be much sleep for me from now until then.....

Ok.....so here's a link to a crummy video of the dyno run on YouTube.

Excuse the tinny sound, but my little Nikon CoolPix is just not that audio capable.
But I'll think you'll get the idea.

Checkout the M&K muffler turning colors during the dyno run.
Guess that 3.6 really puts out some heat?

Doug, since you did the RSR conversion do you still have & want to sell your RS front & rear bumpers?
