I spent about an hour on the dyno at Hybrid-Dynamics last friday morning. Most of my focus went into smoothing out the A/F. 80% of the map used for my final pull came from the IPS supplied basemap. Every IPS K2 dyno that I have seen has a convex rise from 5-6k. I uploaded the tuning map Jeff Evans did back in January with the K2s in my RSX(blowby on cyl #4). Suprisingly, it made decent power. So I took the areas where the Evans tune made more power and pasted all the data onto the IPS basemap to form a composite map. The VTEC point was lowered to 5300. Notice the concave rise from 5-6k now?

I'm very satisfied with the end result. I can't believe how linear the powerband is! This was my first time tuning. I might leave the ignition and cam angles to the pros.

Last friday night, the car went 12.696@110.72mph with a 2.041 60' on BFG drag radials. Some guy let me borrow the BFGs and they were completely bald. I was hesitant to run them but more desperate for better traction.

Here is a shot of the engine bay. The hood barely closes with the RBC manifold.

nice mph....

What tranny are you running?

 

K20A2 tranny with ATS 5.062 FD, Toda clutch/flywheel and Quaife LSD. I'm hittin 5th gear at the strip.

 

nice.... did you happen to dyno before the k2s? if so what were the gains?

 

Great Numbers....super nice power curve.

 

Great numbers

 

Unfortunately, I don't have any before dynos with this motor. I pulled these cams straight from my RSX and installed them on this engine before it even went into the car. And before I installed the K2s in the RSX, I had Toda N2s. And before that, Toda Spec As.lol So no baseline run. I could show you a N2 vs. K2 graph but that just seems to stir **** up.

 

very nice numbers mark!!!

car is very sick... and loud!

 

cool. how much does your car weigh? and how do you like the tranny?

 

Thanks Chris. I'm gonna try and get a muffler on it for next month.lol


THCk20eg, the tranny is fun as **** on the street. It'll roast 1st and 2nd with the LSD! I have no idea how much the car weighs but my estimate would be 2300lbs w/driver.

 

yeah i know i ran the type r tranny for a while. roasted those bitches through 3rd with the 2.4l. thats a nice set up you got there, i wonder how much you would have made without the cams and manifold, they prob netted you some good power.

 

 

DTR POW WOW....

That powerband is FAT!
