Shiv,

weren't the last dynos about 330rwhp? Judging by the videos you have to be sand bagging or the dynos are really conservative. The car pulls so strongly from 60-100. As it is now the acceleration is very similar to a C6 which several hundred pounds lighter and consistantly dynos higher. Can't wait to see your future stages.

Look at sport bikes. The Hayabusa can do over 200. But they still tell you it's 0-60.

0-60 is irrelevant vs. top speed. They're two totally different classifications. I could make a car with really tall gearing with a 200+ top speed but it might only be able to do 0-60 in 10 seconds, conversely, I could use really short gearing and do 0-60 in 3 seconds but have a top speed of 70. (Both gross exageration obviously) Also, 0-60 is more important to me personally because I could care less about 60-100 performance, I'm not interested in racing on the highway. 0-60 is more indicative of autoX and tight track performance where you have to slow down a lot and then get on it again once you're around the bend.

I don't think the DOT can regulate how manufacturers market their cars either.

Vishnu, you're my hero. Now get working on a kit that replaces the stock turbos and possibly a fully built engine

That still doesn't change the fact that 0-60 is a poor indication of a cars performance. Lots of cars have good 0-60's. When one car has 500hp and another similar one has 400hp, they will both to 0-60 around the same time. It takes a much larger amount of horsepower to make a difference at a certain point (i.e. in the short time it takes you to get to 60). Where the difference becomes apparent is the 0-100 or 0-150. On top of that, gearing and driver ability play two huge roles.

Please post more videos WITH SOUND! Watching the needle freak out is fun, but I'd (we'd, right guys?) like to hear the car. What does your prototype exhaust sound like? Please post more videos!!!!!!!

I don't disagree at all that 0-60 is poor. I was simply indicating why it's still the standard.

Understood. It was more of an explanation towards other comments here rather than yours.

I took that video with my digital camera so it didn't have any sound But the sound of the car right now is nothing like the sound will be with the production exhaust. It sounds nice but we hope to be doing something pretty nifty with the design of the exhaust. Mums the word for now but we think you guys will like it.

Alright Shiv, sounds great! Make it happen...

[emos325]

hey shiv,
Thanks for the response. Just a reminder PM me when you got time. ABout how you got started. Anyway keep up the kick a$$ work and thanks for all your hard work.

[jgannonloans]

Hey Shiv, i want to do the Xede, when are you going to be in Vegas or somewhere close? I may have my shop make me a full stainless exhaust, downpipes everything, what size would you recommend with the Xede for optimal tuning?????

By early next month, we should have tuned several 335is in house and out of state. If all goes as planned, we can start shipping out pre-mapped Xedes in December. This means I wont have to play musical dynos in different cities unless there is a demand for custom tuning. And we will have maps for bone stock cars and perhaps those with exhaust systems as well.

Shiv

[jgannonloans]

i would like custom tuning. Please let me know when you will be in So Cal. or Vegas? also what size exhaust would you recommend for optimal tuning w the xede? i want to make sure my car is tuned perfectly due to the full exhaust i am going to have made, please let me know Shiv, thx

[jgannonloans]

Shiv, one more quick question. When replacing the exhaust wo the Xede, will the fact that the vacuum line that goes into the rear muffler not being there effect my driving? will it be corrected w the Xede? please let me know thx for everything

[sstarch1]

I think it was a half inch more, its somewhere in this post.

[jgannonloans]

yeah i thought it was 2.5" also, but not sure if doing downpipes and high flow cats will mean that Xede needs to be tuned slighly differently then a car w stock or just cat back exhaust???? Shiv? anyone?

just plug it with a golf tee... (no joke... search "golf tee mod")

Noob question: what exactly do you gain with custom tuning one of these things? Or, in other words, what differences are there when installing as is versus tuning it... what's getting tuned?

I understand what tuning is in general, just not how it applies here.

Custom tuning is the tuner (me) actually tuning your car, on a dyno. And then testing it on the road. For some reason, this concept is pretty alien for bmw, prosche and audi folks. I guess it's a service that hasn't be readily available for some reason. In the markets I've been active in, it's very common (hence, my out-of-state dyno tuning trips). And by no means are they unique to me. Many other tuners have started to offer a similar service as well.

Non-custom tuning is when the user relies on a pre-set baseline map. On that has been shown to work well on a wide range of similarly modified cars. By nature, the maps are on the conservative side to account for the least common denonimator. So instead of offering 100% of the best possible output, it may only offer 90%. Still darn good if calibrated and tested properly. And certainly good enough to keep even the most power-hungry people happy until a custom tune is feasible.

Hope that explains things.

Cheers

Yep, that helped! Thanks

[jgannonloans]

Shiv, so when is the next time you will be in So Cal or Vegas? and im assuming that if i got a 2.5" full exhaust you could tune accordingly for maximum output? is that the biggest you would recommend 2.5"? please let me know thank you

[jgannonloans]

and oh thanks about the golf tee tip, thats it uh? just plug that hose up w a golf tee?

[OpenFlash]

I come down to LA all the time. But not to do customer tunes. For tuning, several cars would have to be lined up and ready to all be tuned in one day. And frankly, more LA folks come up to our shop in northern california and wait for me to come down there. It works out a bit cheaper and I always prefer to tune on a dyno I'm familiar with.

-shiv

ps.. and yep, just plug up that vacuum line. I used a screw. But a golf tee will work just fine.
