Just be aware ATI balancers usually require honing to make sure clearances are correct. They are not designed to be a plug and play solution.
I had dealer install ATI along with whipple kit when ordering my car. I had a crankshaft snout failure around 12,800 miles taking out entire motor...
So this data log is from this past Friday's test and tune. I run pcmtec canbus flex and had e74 in the tank and 3.375. I turned COT protection off for this run just to see how high cat temps would reach. Ambient air temp was 82 and IAT were 97 degrees at this point in the run. I have the...
When my stock cats failed, I went Kooks 1 7/8 headers with the regular hi flow cats, then free flow, then the GESI. I will say adding the headers added a good amount of exhaust volume sound. The GESI definitely flow much more than stock and get rid of most of the rasp that had existed when free...
I've been whipple from day 1 dealer install. Within 2,000 miles running stock whipple tune my cats were failing. Replaced woth kooks headers and their non green , regular high flow cats. Those lasted maybe 700-800 miles and failed quicker than the stock. This was just from daily driving on stock...
I tried to fight the raspiness on my 800 whp whipple set up. Eventually bit the bullet and forked out the $$$$ for the GESI Gen 2 G sport series cats. Got rid of 90% of the remaining rasp that catless had.
Been a few years at 800+ and cats hold up just fine. I have COT protection turned on in...
My 3.73 torsen did clunk at low speeds. When I replaced it with a 3.31 trac lock, I still had some chunks. Specifically at low turning speeds or on immediate change of position from either forward or reverse. Ended up being a combination of bad driver side wheel hub (they are notorious for...
They are essentially what I got. I originally ordered the Kooks 1 7/8 with the regular non green high flow cats. Once they failed in less than a thousand miles, I had just ran them gutted. Eventually just reordered from Kooks the HO Green that would have nor ly come with the kit you are looking at.
Here's what the exhaust sounds like.
COT on, e74 in tank running PCMTEC canbus flex fuel tune 21.5 timing with 3.3 pulley, 3.31 rear gear, 4th gear to keep speed down.
Made 797 whp SAE uncorrected and 773 corrected.
So this was from past weekend car show. Made 797 whp SAE running about 13 psi gen 2 whipple. This was a 4th gear pull with 3.31 rear gear, up to 7,800 rpm for which I have tune to yank timing. E71 flex fuel blend with 21.5 timing commanded.
Kooks 1 7/8 with HO Green Cats into AWE Touring...
