Well its a little slow in the dyno department the last couple of weeks, so I thought I would post some graphs from a recent car we fabbed up. We made a racecar out of a AP2 and put a full cage in it, Hondata and 3" exhaust after the cat with only 1 exit out of the rear bumper. The car engine wise was completely stock including the stock air box with the factory air filter. The only thing that was done was exhaust and Hondata. Just imagine what the AP2 would do with out a cat and a FIPK

The second S2000 we tested was a AP1. first it was just baselined, then it was fitted with a Nvidia test pipe, FIPK intake finally a AFC Neo made it work together.
Here are the comparisons.




First graph AP2 tuned with 3" catback exhaust



Second graph
Green line untuned base AP1
Blue line FIPK, test pipe, AFC Neo AP1
Red line Hondata tuned AP2




Third Graph
Red line tuned AP2 with hondata
Blue line tuned AP1 with AFC Neo

 

great #'s gotta love F20/22's with bolt ons

With the proper tuning.

 

so this just confirms that santos is dillusional and ap2&gt;ap1

 

Any #'s on ap1 without tuning? Just with the bolt ons.
I have some good bolt ons my self, but not shure if it's worth a 6 hour drive to get it tuned...

Not really. The AP2 was tuned with a Hondata while the AP1 was tuned with an inferior Apex-i Neo.

plus a motor with super low miles vs a higher mileage used motor

damn you both...ap1's are still poop

 

Would be interesting to see the ap1 with AEM-EMS. That would be comparable to the Hondata.

 

cant see the ap1 dyno here at work.... *** red x's Whats the ap1 reading out at???

we love you too, like i said ood #'s for both

 

i would have liked to see each tuned with the same engine maneagement
nice #'s nonetheless

 

impressive #'s on the AP2

 

Tuning with the same engine management isn't going to make a big difference in peak numbers. At the level of modification those two cars are, all a higher end engine management program will do is give you the means to tune a smoother curve.

I've got about 85k miles in what was a factory freak AP1. I ran a 13.87 @102 in it stock and it made 209 on a dyno dyno day when all the others were in the mid 190 range. I was a hardcore AP1 guy for a while.... and then it got stolen and I bought an AP2.

I'm sorry to say this, but AP2s are better cars in absolutely every way. Easier to drive, more power, more controllable at the limit and yet it has higher limits, better interior, more comfortable, better equipped, and better resale value. They are better in pretty much every single way. The only thing I miss about my AP1 was that it revved higher, but I don't miss it much.

 

Well my work is blocking the pictures, but we-todd-did is up and running again?!??

 

nice charts. This really helps show the power and torque difference between the f22 and the f20.

here's another great set of f20 vs. f22 charts to look at.

ha "flite" just made it clear. ap2 is better. this should be posted on the ap1 vs ap2 thread.

 

This car!

 

Thats what it used to look like. It was converted to stock body and hood, for a SCCA T3 grand touring car.

 

God bless the King...motorsports.
I feel like a fanboy in here now.

I don't think that is the case. I saw 6whp peak by switching from a vafc to an AEM-EMS. There is still some hp left on the table that can be coaxed out by playing with timing...which a vafc cannot do, but the Hondata and EMS can.

 

Gaining 6whp by playing with timing on a stock car is a little beyond normal. I would guess an average to be around 3whp by playing with timing. Factory timing will always be set VERY near perfect as long as the car stays stock. Any more in one way and your're going to have reliability issues, too much in the other and you're going to have problems with emission testing.

There's far more peak hp to be gained with a/f modification than with playing with timing on an otherwise stockish car.

Bottom line, AP2s are better, regardless of which engine management is used.

 

Damn 220whp out of stock (essentially) AP2, that's impressive.

The cars above are not stock and have test pipes...as does my car. Emissions testing was not a consideration of the tune.
