Rob 97 993c2

hi guys,
im posting this on behalf of a friend looking to modify his 993tt (of course, im STILL looking for a nice silver tt for me...) .

Anyway, what do you guys think of the FVD stage 2 package .. includes programmed ECU, upgraded turbos and 5fuel regulator. FVD claims approx 480 hp.

Is this a good set up? He would be using car mostly for street on the east coast and about 7-10 track days per year. He is more interersted in low end or constant torque rather than crazy power at the upper end or going over 200 mph.

Is this very different than the ruf package? Can this be run w/o the secondary oil cooler? Any other maintance issues that he should be aware of?
thanks,
rob

Hi Rob:

I'll not comment about the upgrade as we offer something similar, but I will unequivocably state that ANY 993 TT requires an additional front oil cooler if the owner expects the engine to live long.

Additional power equals additional heat, and must be dissipated for the engine to last. Anyone saying otherwise is simply irresponsible since any vendor providing the upgrade would stand to profit from the consequences of a short-lived engine.

I was about to say what Steve said. Even the Turbo S has uprated cooling for a mere ~22hp extra.

Rob 97 993c2

ok, agreed on the oil cooler.

any comments on the FVD stage 2 480hp setup??
is there much lag b/c of bigger turbos?
how does this compare to Ruf 490hp setup and other stage 2 systems?

Obviously I won't comment on the kit, I will leave that to people who have purchased it, but wanted to confirm Steves statement about the oil cooler. While we require it for level 3 and up we do reccomend it for level 2 also.
Let me know if your friend needs any help

I don't think it's any reflection on FVD if a given car has their kit and the owner neglected to go with aux oil cooling. I think it's good that FVD (I presume) quoted 480hp because I understand that to be the flow limit of stock Porsche factory "GT2" turbos -- around 476hp.

In terms of daily driving, these engines make impressive torque -- and be mindful of the internal limits of the factory engine ... repeated excursions beyond 500 ft-lb will be expensive.

I think it would be prudent to put the car on an AWD dyno and check power, torque, boost and air-fuel ratio results from 3500rpm to 6800rpm. If the boost is controlled precisely and the a/f ratio doesn't waiver, the engine would be impressive. That, combined with a simple compression _and_ leak-down test is the best I can recommend to establish the health of the engine. It can still drop a valve at any moment or bend a rod or find any number of other ways to self-destruct -- there's always an unknown quantity when buying modified engines.

Crazy Power at the upper end, probably.

ScottMellor

The lag caused by the bigger turbos is significantly ameliorated by cat bypasses though........

OK Scott, it you want me as an instructor in Willow Springs, you are going to need to find simpler words or we are going to have issues.....

ScottMellor

Sorry. (I'm the product of the British educational system.)
I'm sure we'll do just fine.
Instructors are usually just saying "NO! NO! NO! NO! NO! NO!" to me

OldGuy

WHen are you guys gonna be at Willow??

ScottMellor

May 22-23 with Tracquest.

OldGuy

I'll have to come down and visit.
Dont know if I will have enough cash to
play but I got a new job and I'll travel more
so I should be able to do an event shortly
unless I can figure out a way to give VBob
some more money!

viperbob

Well you better at least come down and hang out and maybe get a ride...
