What mods is this with?

 

with headers,mufflers and the V-AFC .. i lost 10HP from the 18inch wheels.
so i should have 235Hp at the wheels.
with AEM intake the car will have more than 240HP at the wheels .. i guess thats good after all. but the car feels way faster than before ... ask Nova he had a ride in the car today .. we went over 100MPH in a back road hehehe lol it was fun.

Did you tune the AFC yourself or have your installer or someone else do it for you?

And with the springs do you think that you get less wheelspin due to less squat (correct term?) while accelerating?

 

a professional tuned the V-AFC ... and i dont think the spring will do any difference in wheel spinning.

Damn thats some sweet sh*t... very nice.

NOVA, the pdf is kinda blurry/soft... could you sharpen it up a bit? Or convert it to a gif/jpeg or somethin?

soopa... but i was expecting more HP at the wheels :-(.... the car feels crazy .. i wish that the supercharger is out now ... i would buy one right now...BRINNNNNNNG ME A SUPERCHARGER.

224 HP at the wheels with about an average 20% drivetrain loss means your running about 280hp at the crank. So, you only gained 20hp at the crank from headers AND the V-AFC? I also suspect you have other mods as well probably too so, for some reason I think you should be higher than that dyno specifies. What were the conditions an what altitude are you at?

Well they said i have 23% loss in the Hp and 10Hp from the 18 inch wheels.. so i think 225 is fair. they said i have 280+ at the cranck.

AGH, didn't see the part where it says you lose about 10hp due to the 18" wheels. That makes more sense then. Though only 30hp at the crank (or 24 at the wheels) for header, mufflers, and V-AFC is a little low in my opinion based on the "claims" made by the manufacturers isn't it?

(I also just realized that you cannot delete your own posts!)

Well then i guess the manufacturer are BS... in the site for comptech they said it will gain just 27 HP for the headers... but i dont think that is true after i saw my car on the dyno today... and i have V-AFC and mufflers too.
i gained about 35HP at the wheels from all my mods... thats nothing i guess.

Anyone out there know of any existing dyno results from a stock 3.2CL-S? (or know someone who wants to dyno their car and post the results here?) That would answer a lot of questions.

I think the v-afc gives a more higher boost than hp. look at the dyno. after it was tuned his hp was much higher but his over all max hp is only 4hp'z more. sorry about da blurry pdf. its from a hp digital sender.

stock Cl-S will range between 195 to 200 Hp at the wheels .. i saw alot of guys who dayno'ed there cars in www.

O.K.-stupid question.

Why would you lose 10hp going to 18" wheels if you keep the same rolling diameter. How would unsprung weight effect your horsepower?

Here's my pre-headers dyno. I'm have it dyno'd again next tuesday.

Nova's right. You're not gaining much on the top-end with the AFC but if you look you'll see that you gained a ton of low-end torque... that's what you're feeling when you take off... you won't feel high-end torque, you'll just notice that your 0-60 time gets quite a bit faster :-)


All-in-all they're quite impressive gains.

 

my gtech runs were about 5.8- 5.7 and the 1/4 mile about 14 flat at 100 mph.

Mike:

I can see the different temps on your runs. Did they do any adjusments between runs. What was changed between each of the three runs on your graph? (Thanks for the graph -- more calcs to do...)

BeatYaAll:

I thought you posted that run with a 13.9 -- yes/no?



[This message has been edited by EricL (edited 01-02-2001).]

 

yeah 13.9402 something like that was the best run. i meant by 14 flat the average of my runs.
he was playing with the fule chart on the V-AFC and increasing the fule based on what he see on the dyno runs everytime.

Sorry, I addressed the 3 graph question to Mike (and his dyno chart).

But thanks, that does qlarify what was done there for YOUR increase!




[This message has been edited by EricL (edited 01-03-2001).]

 

This is a good question. As far as I understand, both the stiffer sidewall of the tire and a large part of the wheel's mass being pushed out half and inch further to the edge of the wheel (compared to a 17" wheel) can increase the wheel/tire combo's rotational inertia. i.e. it will take more force to get the wheel moving which may show up as a loss in power on the dyno (and maybe a little slower acceleration). I guess you could say it lessens the efficiency of the total system.

What about 19's...

i got 19's ...how much hp (estimated) will i lose?

1/4 time too? what should i expect

 

The guy said .. u will lose HP on the dyno .. but on the street its a different story... he said the lunch will be a bit slower but after the wheel is on the ground and accelerating .. u wont lose anything .. u will gain more speed from the larger rims when u go faster and faster because it does larger space than the smaller ones.

Right. And you get the added benefits of a larger contact patch for better grip and better turn in and response from the stiffer sidewalls (not to mention the fact that you're driving a car that looks even better with 19" wheels!). Might be a little more road noise though, and you might bend your alloy wheels on bad potholes, but those are the breaks!

The story does make sense -- it sounds like a case of energy conversion. The car's wheels initialy rotate slower (due to the rotational inertia). Once the tires do "hook-up", the rotational inertia "dumps" that rotational force back. Kinda like a big spring -- store up energy to push it down, then recover it when you let it go.

So... Did they ever have the dyno running at 6200 or 6400 rpm and measure static power output?

 

nop, honestly i didnt think of that.

Yeah, but in the quarter mile, the extra weight of the rims and tires increases the rotational mass. Every 5 pound increased weight in a rim/tire combo equals about .1 in the 1/4, and using the extra mass i lose abut .4 in the 1/4, which is actually where cars with similar mods to mine run (14.0's) with stock tires. Of course, there's only so low you can go on the weight and the size as the size etc. also factor in.

No adjustments betweens runs. I know the graph is kind of strange looking but with each successive pull the car got stronger and stronger. I've been able to replicate that with my gtech too. The car gets stronger with successive runs.
I guess it likes the punishment!

Wait, after the 1st run I asked them to use their fan.

 

Take it to the track!

 

When you talk about the 5 pound increase in wheel and tire *are* you talking about:

1. Same size/similar wheel?
2. Or different wheel/tire (still with same rolling diameter.

I've had this (HUMMMMMMMM) kind of question going on how someone could make something like a composite wheel:

1. It would weight the same as the original wheel (weighed on a good digital bath scale for example).

2. It would be have less material and mass at the outside of the rim (a wild example would be a wheel with aluminum spokes, but a titanium rim.

3. So now you have wheels that weigh the same (or a bit less), but with less rotational mass.

Does any wheel maker provide a rotational mass figure?




[This message has been edited by EricL (edited 01-03-2001).]

 

I never thought of something like that, I think decreasing the weight while doing what you mention would be the best scenario. Why do you think that racing rims weigh very little and are quite expensive?

I weight just over 115 does that mean If I drive Beatya all's car I can hit 13's?

Ir has more to do with the weight of his wheels. ACE wheels aren't very light. They are usually in the high 20 lb. range. By increasing the weight in your wheel tire combo you are increasing the unsprung weight and rotational mass. The increase in rotational mass is what will rob you of some ponies.

 

i knew they slow your car down, but i don't believe they take away hp....but arnold, if you say they do...then they must

ClPower,

You do lose HP on the Dyno, maybe not as much with our V6, but on a 4 banger,the lost may be quite substantial.

Two examples: 1)Eurosports (Performance shop in my area) did a Dyno comparison on a Civic DX sedan with a 17" TSW rim/tire and a SSR 17" rim/tire combo. They gain a 5-7HP peak HP.
2) On my previous 96 Lude Si, my 1/4 mile time decreased from 16.7 to 15.9-16.0 after changing from 17x7.5" AV5 to SSR 17x7 Integral with same tires. The weight difference was 22lb rim vs 17 lbs rim.
