Evoms and the car was built by sharkwerks

 

Hey I used to own a 790 whp 05 c6 and also had a bolt on 11 grand sport. Great cars mod well. Also had a 600 whp 996tt and just bought a 997tt. Ill tell you the power curve in a porsche is totally deceiving. The car doesn't feel anywhere near as fast as it is. You'll have to go out to race some thing to see for perspective. There's times I kinda miss the feel of the vette but don't think I would ever go back into a vette unless I could keep the 997tt. I've never drivin in a viper/modded viper but I'm sure it's comperable to the vette.

 

Iv owned both a highly modded C6Z and now a highly modded 997tt. Both are great cars. Would I sell my Z andbuy my 997tt again? Probably not. I just now got my EVT775 in order and running 100% and I love it but I loved my Z as well w FAR less hassle and FAR better support from the experts who built it. Maybe im just a bit disgruntled as my EVT775 997tt ownership experience hasnt been stellar but Im working to change that.

The Z:


The TT:

 

What about the ZR1? I was thinking to buy a ZR1 before I bought my 997 TT but I didn't do it because the C7 is coming out and I didn't wanna buy a car that will lose 50% value in 1 year...

 

V10nut I think I understand what you are describing, and your experience is expected especially for someone coming from big hp naturally aspirated V10s and V8s. The immediate low end torque you are accustomed to in your Viper and even in the scud is "delayed" in terms of feel with the TT, even when tuned the TT will not "feel" as fast in the 1800-2500 rpm range due to the smaller displacement and turbo lag (unavoidable)

I had a similar disappointing experience when I test drove my first TT (I was also coming from a large 500+HP V8 with tons of low end torque), it felt sluggish. But with a tune and learning to drive it as intended I can honestly say that the 997.1 TT with a tune and exhaust is one of the fastest cars I've driven.

Coming from larger displacement NA engines you need to adapt your driving style to unleash all the power in the TT and enjoy the beast. Just make sure you keep the rpms in the 2500+ range and learn to down shift more often to keep the rpms above this range. A big V10 is forgiving in this regard, especially if you are lugging it at 1500 rpm, you can floor it and the power/torque is immediate. If you do the same in the TT it will feel relatively sluggish in this rpm range so you need to downshift and get those revs over 2500 (3200 if you don't have a tune!)

But if you keep the engine in the power band then the torque and power is amazing and should faster than your scud and as fast as your tuned viper IMO

I guess maybe I was disappointed in the performance for the money aspect. The evt700 kit is 17k plus. I can build a stroker motor for my Viper and get 650 to the wheels na out of it for 10k. My friend just supercharged his Viper and got 700 to the wheels For 9k. I raced him in my 997 and lets just say the results were embarrassing. My car has 70k in upgrades, for half that you can tt a Viper and get 1000hp to the wheels. Would someone please explain to me why euro guys rate horse power at the engine and not the wheels. Does it make them feel like they are getting more? Evt700? No more like EVT580. Don't get me wrong, I like the car for what it is. It is much nicer than the Viper but if you are just looking at performance the bang for the buck this isn't it. I am looking to upgrade the intake; 2k for the upper hoses, 1500 for the lower ones 2k to install and 3k to tune. Expected result... less turbo lag. I almost fell of my chair laughing.

 

EVOMS claims a trap of 137-138 for their EVT package. What does your 997TT car trap?

 

Thank God I bought a car already built! I'm not giving up on it yet, my car is painfully beautiful. If there is some good outcome from the future mods then I will keep it.

 

I personally feel Evoms is overpriced! I hear more about people complaining about there experiences than being happy. I've talked to three different people with the evt775 kit and asked them if they could do it again would they and they said no. 28k for a vtg kit is so overpriced IMO. I would go with the AMS alpha 9 kit or Switzer P800 or a custom set up through protomotive for half the price. Your basically paying 28k without install for 625whp with the 775. That is actual dyno #'s posted by Evoms on 6speed incase you wonder where I got it from. A lot of the parts for this car is way over priced. I came from a e92 M3, the exhaust went along the whole bottom of the Car and ran 2,500. On the 997tt it's a 1/4 of the piping and twice the price! I do miss the all motor feel as well. I'm def looking forward to your 6 month ownership thread!(triblk6speed)

 

Prior C6 Z owner here. Bought it new and eventually built the motor, trans and rear diff and put a TVS blower on it. Made 722 whp. Sold it for another Porsche. Sounded good and was somewhat quick, but it was not even on the same level as a P-car from an overall perspective.

With regard to Vipers, I've found that TT Vipers are almost identical in acceleration to Porsches at the same HP level.

No only Evoms but a lot of other power kits out there are overpriced. I think is always better to get your own hard parts and a good tune.

 

When you do that, you risk buying, then selling, then buying, then selling, over and over again until you find a combination that works. Cost savings can be hit and miss depending on what combination you end with.

 

Some really good conversation going here. On a car forum it's really refreshing to see an adult conversation rather than a 'my car is better than your car' sh*tshow.

The last time I took the Z out I was enjoying it on the freeway. The thing just pulls...pulls, pulls.....3rd gear, 4th gear, even 5th. Truly a great experience...mashing the throttle...hearing the snarling exhaust and feeling the car hurtling you forward and not wanting to stop. I don't want to lose that.

I've had turbo cars before and the experience just wasn't the same. It's more of a climax that builds- as opposed to an instant burst of gratification as with the 7.0L V8. To be fair with my old turbo cars I wasn't talking 500whp.

But from reading the threads here for some time, I have a hard time believing I can achieve 500awhp easily with a tune and an exhaust on a 997t.

Can a tuner chime in here with some factual data? I'm not going to be happy with a car slower than my Z that costs 2x as much.

 

I just flash my car not too long ago and next week I'm getting EP1 (the most popular tune & exhaust in the forums) I'm planing to take my car to the dynno as soon as I install EP1. We'll see if I can make it to 500 WHP

I love the 997TT but I think the Z06 is faster and the power is always there.... (I'm talking about stock cars) I'm sure my 997 TT is faster than my Z06 but my vette was 100% stock.

 

My old 997TT trapped 130s with a tune and exhaust.
