K2 being "tweaked" - 457RWHp and climbing

Getting my additional mods done by C2Designs in Tampa.
They dynoed my present K2 @ 457 RWHp (uncorrected) and it was rich up top. They're having Kleemann take some fuel out and expecting in the neighborhood of 490/500 RWHp.

Chris put on the EVO rotors and CCW wheels last week and said that it's
breaking loose my 295/30/19's in 2nd gear while rolling in 95 degree heat!!

It sounds like I'm going to have an animal on my hands when I get it back....
Looks like the K2 is everything advertised...I'll post pics when I get the car back next week.

This is what my wife will be doing to me when I'm driving with her as a passenger

Did you do a baseline dyno before adding the K2? If you did what did you put down, I am curious to see what the K2 added for you.

My baseline dyno was 410rwhp and 441 rwtq

At present it is 457rwhp and 519rwtq and is rich up top. (Dyno uncorrected @ 95 degrees)
BTW-the post k2 dyno was done W/O the lightweight wheels and rotors

You should put the stock contis back on and see if you can break the rear loose in 3rd. Probably break it loose in 4th and 5th on wet pavement.

mmm, fun.

My K2 is putting down 474rwhp and 551rwtq. That was with the older K2 ECU tune. I have since flashed the ECU with the newest K2 prog. Hoping to hit the dyno sometime this week or next.

Ken - that will be awesome if they can tweak it up over 500rwhp just on K2.

The bigger variations are going to be in the Dynos not the K2's.

What K2 porgram do I need to get from Kleemann if I have E.Race exhausts ??? More rich or more lean ???

They ask 1750 EURO just for an ECU

A few reasons - I know that there are at least 3 or 4 minor variations ("files") that Kleemann uses on their K2 tunes giving consideration to Altitude, driving conditions, octane(I promised them nothing under 93), Location-ie: HOt, humid, How lean you want to go-ie: 12/1, 12.5/1 13/1, etc... Blah-Blah-Blah.... All of these factors can give you 20-25 hp variance in an instant.
With all this - you're still with-in an 4-5% variance!!

Ken,

You wont see 500rwhp with just K2. I estimate 480rwhp, 560rwtq.

Ah-not so fast "Gwasshoppa" - Actually I was happy with what I had!
Chris @ C2Designs wanted to tweak the set-up a little bit as he is an
ex-Ferrarri mechanic and is a stickler for having everything right!
He has openly stated that when driving my particular - "E" - that it is one of the stronger ones they have experienced

Even 480/560 will be quite the machine!! Kudos f/K2

BTW - I'm predicting 485ish and 540ish......Any other predictions out there??

Strong or not, K2 just cant make enough airflow to hit 500rwhp. You need the TB and more airflow mods to break the 500rwhp mark.

BTW, I was being generous when I said 480rwhp, 560rwtq.

With the stock exhaust and primary cats removed 480rwhp should be attainable given the proper tune. 560rwtq with those big headers will be tough.. I would say 550rwtq will be more than likely on the high side.

All in all, it will be one heck of a nice car you will end up with.

Get Cory to add the 80mm TB and you will probably be at or break the 500rwhp barrier.

Good luck and CONGRATS!

"Get Cory to add the 80mm TB and you will probably be at or break the 500rwhp barrier."

Do we have a definite GOOD working 80mm TB yet?? With perf #'s??
I'm thinking about Kleemann's but I believe their's is only a 76 mm??
Where do you sit with your project on this
