Do those chips work by advancing timing (I don't work on new cars, so I don't know these fancy computers and whatnot)? If not, I think if someone lives in an area with 93 octane gas, seeing how the C only calls for 89, I bet you could advance timing like 2 degrees, start using 93 octane, and see some gains.

Yeah I remember! Some one mentioned a problem with the electronic throttle control on the C. What happend with your nitrous set up Vanilla...?

Vanilla, try doing back to back runs with and without the K&N. From what I've seen, without a high flow exhaust, a high flow intake does you no good, and I even saw in one instance of a car getting less power on the dyno with a K&N than with a stock filter.

From what I understand things like Super chips micro tuner and Jet require that you run a higher octane gas with thier products for the performance increase due to timing advance and less knock correction. Other things these chips do are:

Remove the speed limiter
Raise the rev limiter
Change the tranny shift points
Adjust Thorttle position
Change injector pulse width/fuel maps

Thats a good run, I need to know your 60 FT. times with the BFG's. I am looking at getting a set. Can you post all the info from your timeslip so for reference? Thanks, QB.

We don't want to raise the rev limiter on this motor..... It's set where it is because of the light valves used for the MDS system... I'd hate to see the valves bit it because I wanted an extra 500 rpm out of it. Besides, probably not alot of power to be had up in those ranges.

Yes, I'd like to know the 60's myself. Keep in mind he has KDW's not drag radials.

Tires

I'd get a set of drag radials if they made any that fit our application. They are all too short and wide. The common assumption is that a wide contact patch is good for drag racing, but a long patch running parallel to the length of the car works better. I used to run a 9"X29" stock eliminator slick on my Turbo Buick and it would short in the 1.45 to 1.50 range. I know the KD's are not going to hook like a drag radial, but I'm hoping that they are going to be some improvement over the stock tires. QB

That's part of it, but you can also add a lot of area under the curve by altering the mixture. Modern cars run really rich because the engineers use the unburned fuel to cool the catalytic converters to prolong their lives. For a well-optimized factory setup, it's tough to add much peak power with a chip - most of the gain is just area under the curve. When you make other changes like less restrictive intake and exhaust, or change rear end gears or add an underdrive pulley the chip becomes more useful because you can compensate for those mods.

With modern computer-controlled transmissions, chips can also be used to firm up the shifts like a shift kit. You can also use it to change shift points.

Vanilla, I need to know your 60' times with the BFG 255's, please post your time slip info so I can see if it is worth the expense. I've tried contacting you offline but no response.

14.01 is a great ET, but you said in a post on April 1st that you already have the Jet chip Stage 2. :confused: Please set the record straight, sharing this info helps us all. QB

I ran again last night after installing Volant. Times were not much improved. I first added Borla and seen a .2 improvement (14.8 to 14.6).
Last night ran 14.5 @ 98.5 mph but air temp was 15 degrees cooler than the week before, so I didn't see any real improvement with Volant. I think stock intake is OK until adding headers. BTW, my 60' times are crap (2.35). Tires would help there. Or maybe a better driver.
