Nice number! Thanks for your sharing. I think this is the first 7DCT Dyno data here. It is very useful . So the 335is JB4 whp you did is above 360 whp.

Cobb vs JB4 - AFR's...
Many state Cobb AFR's appear to be more safe for the engine, however, I have not seen anything that would show any additional wear on the engine due to JB4 AFRs. Am I correct in saying the JB4 seems to mimick the stock AFR trends more, as they inch down a little more throughout the powerband rather than dropping down abruptly with the Cobb tune? (see page 8) |

Actually the JB4 or any piggy do not have the control over fuel as the flash do. Therefore they rely on less fuel, less boost, more timing down low-mid. hence the leaner AFR down low on the piggies. Personally i dont think it makes a difference which way you run. However cobb gets more torque down low out of the equation.

No DCI the car is pure stock except for the tune.
I had about 4 gallons mixed in a full tank of 93. Comes out to just about 94 octane. If I was using straight 100 or a 80/20 mix of 100 I would have run Map 7 for considerably more horsepower based on the butt dyno & speed to distance of a known section of a 540 on-ramp. 365whp is my everyday DD number with about $30 ($7.50 gal) of 100 mixed in when I get gas. Tank gets topped up with Costco 93 to keep the overall cost manageable. If I run straight 93 I go to Map 5 as an insurance against detonation since I have stock downpipes. Since catted downpipes would cost me about $1000 & be noisy too boot (prefer a semi-sleeper, small Burger Motorsport decals are the only giveaway to the knowledgeable) I figure buying small amounts of 100 is a better bang for the buck + makes warranty claims & state inspections a bit less painless on my knuckles.

You need to ask Terry, he gave me suggestions on what to run w/o downpipes but not the details.
In stock form without the JB4 it dynoed 314whp - 375ftlbs on straight 93 octane Costco gas.

From the top of my head, i would say yeah it does run lower timing and a bit more boost than the x35, hence the added torque. That is a lot for a stock car..NICE.

Good numbers in here! I was dissapointed in my dyno. I should have done a baseline to see the delta hp/tq. I made 335/349 with jb4 map 5 on 91oct, dci, and AR dps. I have since installed a code3 intercooler and a meth kit is on its way. I hope to push around 390-400whp on map 3.

My understanding is that 91 can really whack the out put of a turbo motored car. The meth should move you right on up.

On a dynocom my car made 280/300 stock, 330/380 stock on cobb stage 1 and i'm eagerly awaiting a chance to see what stage 2+ makes. Like BEAR said, octane is also hurting you. |

Torque on the baseline is not absolute as we were having trouble with the pick up & it could have been less. That is why the baseline graph only shows WHP vs time.
The pickup was replaced with a new DynoJet part before the JB4 runs were made.

I made 442lb.ft tq last week. To my knowledge that's the highest torque reading from an xi. I could be wrong. Graph and explanation posted in xi section of this forum
