Ody - Tomorrow huh? Sweet, we've all been looking forward to this day!!!odysseus said:Personally, I'd dyno it both ways. With 20's then with stock rims and tires. I'm hoping to be at the dyno tomorrow for the great cold air intake challenge part deux, and I'll be doing that for at least a comparison. My first run will be as-driven. All others will be with the stock 17's. Bigger wheels weigh more and have much higher rotational inertia than the stockers. The motor has to overcome this, as well as accelerate the car's mass. It will make a difference, but how much is the question. It may be 'in the noise', but 'while your there', you might as well do the runs.
My stock wheels are 16's. I have to drive to L.A to pick them up but tomorrow is the Marine Core Ball so hopefully I will have time to run it with both.odysseus said:We should have some good data comparing the HP for stock wheels, 18's and 20's if we both can get runs in with different wheels. Marine, do you still have a set of stock wheels to try out?
For a happy meal, I predict 245 RWHP (around 290 at the crank) for the marine. I'm only hoping to break 200 RWHP for my runs tomorrow. :crying2:
I only ran it with the 20's because I didnt have time to switch them out since it was the same day as the Marine Core Ball. the Headers and cats gave me a 35hp increase. I think if I was to run it with the stock wheels it would easily break 250hp. before headers I ran at 203 with the 20's05CTS said:Can we get a little more info? Did you run the 20's or the 16's??? What were your #'s before the headers were put on?? Do you really think the headers made a big difference, number wise???
Wait only 238hp, that cant be right, Ody got 244 with just the K&N and a Borla.. 238 is an 18 hp jump not 35HP, 35 would bring u up to 255HPSdMarineGuy said:...the Headers and cats gave me a 35hp increase.
He's talking RWHP. I only hit 203 RWHP with the Borla, K&N, and stock wheels. That translates to 254 at the flywheel (34 HP over stock at the flywheel).BishopRuger said:Wait only 238hp, that cant be right, Ody got 244 with just the K&N and a Borla.. 238 is an 18 hp jump not 35HP, 35 would bring u up to 255HP
am I just misunderstanding the numbers or what :bonkers:
