the curve in relationship to rpm will remain the same. Just less drive train loss (few more hp's) and the time to rpm (how fast it revs) will be quicker.

...my guess at least

 

they both have A.D.D.

robyn got a TT and kirby is onto other things other than porsche (it appears).

i wanted a porsche with power to track/race it and not worry about balling it up. my 996 SC fits the bill. sure i would be upset but i won't be turned into a blubbering idiot if i wadded up a gt3 or TT.

still no track report. a little bit of a snafu. as i was leaving for laguna seca, my driveway curbing managed to clip my bumper and rip it off. no track for me, arrgghhh.

 

I have debated this issue long and hard over several vehicles – turbo or SC?

Clearly, there is a monetary factor. For example, Prototech will be happy to take $35,000 off your hands in exchange for a claimed 550 TT HP. What’s D-Dog got into his ride for 50 HP less? 180 HP for what, $15K including installation? That’s the best damn HP deal on the planet.

Next, we get into the power curve. Personally, I do not like turbo power. I’ve had a turbo motorcycle, an RX-7 Turbo with lots of work, an Eclipse Turbo, again with mucho HP mods but front drive – Aggggggggg!!! And a Supra Turbo that dynoed 788 HP at the wheels, which defined the term “peaky.” At 4000 RPM it felt like getting kicked in the chest by a Clydesdale. I’ve also had the pleasure of driving an F-40, a worked 993 TT and a stock 996TT. All of these vehicles universally exhibited – to one varying degree on another - that kind of abrupt, grab you by the back of the head and throw you back in the seat power surge. While fun in a straight line, it’s a lot of work in the twisty stuff to have any real fun. And the bike? Definitely don’t be leaning over when the turbo comes on. Nope, you can keep your turbos. I don’t like’em.

I have not owned an SCed car. I have, however driven several – all V-8’s with lots of HP, and I did fractionally own a 41 foot Magnum with two SCed Merc V-8s. All of these motors had gobs of low end torque before the blower, so the power always had a nice linear pull until the revs really got up there and then all hell broke loose – but that’s what you’d expect.

I’ve spoken to Todd at Evo and read many of your posts debating the issue. I would have to believe that, if you can’t build enough power normally aspirated, then the blower makes more sense. Believe me, there is nothing more I’d like parked in my garage (next to a Carrera GT of course) than a big phat-*** TT that’s been massaged to the other side of 600. It’s been that way since high school and will probably persists until I eventually park one there. But for real world every day driving that includes wide eyed blasts up your favorite on ramp and the occasional track day, I would have to surmise that a well engineered, moderately powerful SC kit that enhances the already striking characteristics of Porsche’s flat 6 has got to get the nod. EVO’s kit seems to be the class favorite and at the price/HP quotient they offer, I can’t see how you could beat it. Especially if it works as well as you say!!

 

i was just being tongue in cheek. you know... you always want what you don't have . it's got loads over a NA3.6, it's a silly comparison

i am definitely doing fine w/ my go fast bits

i DO want to get it on a dyno but i want to do it once i get my data logger on and i haven't had the time. will do very soon!

 

Haha and you _thought_ James did it! Actually he was sick that day so I stepped in. I was wondering does the AC Compressor go in the front or the back... The bonnet of the boot? Nah but seriously we're doing another one on a 3.4L two weeks from now (an 01) and once that's done, I'm already scouring the local area for a fun 99 project car. I'm still going to go with NON-Egas.. then do a blower, motons, strip it and um call it "Karlooz II". The 3.8L 997s SC car certainly has some extra oomph to it.

Also we've done many 3.6Ls as well and I honestly don't feel there's "that" much of a difference. There's "some" but then again the 3.6L cars are heavier etc.. and most of the 3.4Ls we've done have been coupled with light weight flywheels which negate any difference.

 

No dog, your report was honest, just Carlos' was more from a track rat's perspective as opposed to street stuff. I run in the advanced run group, as does Carlos, and was interested in his input on the subject. As for Robyn and Kirb, it's just they were so pro sc and just seemed to drop them like a hot potato, gotta be more to the story than just movin'n up. Who knows aybe they got a huge discount.

 

hey, how do you troll the boards AND install superchargers at the same time

like DDOG said, the SC amplifies the existing power/torque curves. so with the NA3.4 and 3.6L there's a 30HP difference but after the SC then there's a 60HP difference.

it's funny, there's a pulley difference with the 3.4 and 3.6L kits with the 3.6L receiving the larger pulley, therefore less boost. is it because the 3.6 is volumetircally more efficient than the 3.4

 

Yups you can't argue with physics:P Anyways I like the 3.4 myself... and I'm going to get one Besides I have a boosted 3.6 POS already! Trolling wirlessly whilst flashing is the only way to go... However when install GT2 decklids.. Um...

 

you wanna trade then?

 

James would love it if I did.. No more Tip-nightmares!

 

. just put in a 6speed tranny. easy fix right?

 

Gotta blow up that Tip first Doesn't want to!

 

I would love to see a "stage 2" upgrade to the EVO kit by EVO...that's what the 996 community needs***

PS: Someone close to Todd and EVO prod them to get started with it already!

 

Haha ! That 3.4 Sharky mentioned would be mine. I'm looking forward to getting it done.

I already have a set of nice pipes and headers that Sharky (at Akkurat) sold me (and currently GIAC software and evo vflow - which will be replaced as part of the SC upgrade).

Sharkwerks were amazingly helpful. Both Alex and James are totally enthusiastic about these cars and seem to just love working on them.

I did a lot of reading before I finally went for it. The dyno charts over at EVMOS look great, same nice, almost linear curve, but just much higher up the chart.

By all accounts, more usable power as it's so progressive, rather than the "clydesdale kick" of the Turbos.

I was extremely lucky the day I showed up at Sharkwerks as there was another 3.4L that showed up and the gent was gracious enough to take me for a spin.

I think it may have been "karlooz" - the car looks very familiar.

All I can say is that the difference was night and day.
It seemed like it would play well with others in traffic and yet when opened up it totally howled.

I was surprised by the lack of supercharger whine.

I once had the misfortune of owning a Merc SLK and that thing whined continously and made no horsepower. I was surprised to only be able to detect a little whine from the back, which would easily be drowed out by the whining coming from the passenger seat when cornering hard with the g/f in there.

Driving my 3.4 back from Sharkwerks was awful, It felt so slow compared to the machine I'd been in not half an hour previous.

My only worry is the CARB cert. I nudged EVO last week as to the status, but have not hear back yet. I'd like to avoid having it removed in December when my smog is due, or possibly find a blind, stupid smog shop. They must be out there.

:-)

 

it was my pleasure
