How to make 30+hp for $500 or less... (DX/LX F22A1 only)

[aRaKNiD]

The 90-91 EX has the F22A4.

Good to know...This is my 3rd CB but I'm really just now learning all the technical stuff. Which may be pointless considering I don't know if mine has been reduced to garbage or not..."Radius Rod Connects to..." thread explains more about that.

or you could loose alot of spare weight and gain even more than 30hp for $500

example of the formula..

(w) stock weight: 2800 lbs
(h) stock horsepower: 140hp
(w2) modified weight: 2700lbs

((h/w2) *w)-h=hp needed to gain similar results

worked out:

140 hp / 2700 lbs = .052 hp/1b

0.052 *2800 = 145.19 hp

145.19 - 140hp = 5.19 hp would normally be needed to propel the same car at the same rate as loosing 100 lbs.

don't let this seem complicated ,, really look at it and study what i just did, it's verry simple and a great way to see the power you can produce by loosing say 100lbs or say 400lbs.

this also helps you calculate how many people in your car you can have to beat another vehicle in a race. It'll also show you that you being the only person in your car during a race is key to winning.

also depending on what style of racing you like a great suspension setup can account for better acceleration and speed.

i realize we are talking dyno #'s but i figure this would be some good info to share as well.

Deev has a great layout for the parts to be bought for the unpgraded a1..
if capable i would highly recomend the H tranny upgrade as well to firmly give you the feeling of all your power, thus allowing it to hit it's peak faster to the ground, allowing you to become a better skilled driver with quicker shifts allowing you to accell in power and skill

ok my question is kinda off topic....but does anyone have a picture of a f22a6 ecu and the stock f22a1 ecu...My friend has a accord ecu in basement plus I think i have a f22a6 ecu not sure

[cornell25]

thanks for the good insight on some possible upgrades

This won't work with an EX? I thought that the DX, LX, SE, and EX had only to do with the interior of the cars...

The DX and LX have the F22A1 motor. The 90-91 EX has the F22A4. The 91 and 93 SE and 92-93 EX have the F22A6.

This will work on the F22A6 just fine... BUT, you won't gain 30hp. The point of half of these modifications is to convert the F22A1 to the F22A6, which is a 15hp difference. The F22A6 would benefit from the H23 intake manifold, and MAYBE the P12 ECU. The F22A4 header is likely to produce some gains as well.


In the end, you'll make just as much power by starting with an F22A6, with less work. However, the impressive gain can be had by starting with an F22A1 (I did that because "gain 30hp!" is MUCH more impressive than "gain 10-15hp!"

How long do you think they'd survive on all brand-new stock internals?

[deevergote]

The stock F22 internals, with 15 years of wear and mileage in the 6 figure range is not a revving monster. Neither are those tired old valve springs.


If you're going to do simple mods, keep within the stock limits. If you want to rev more, build it so it CAN rev more.




"Oh, I tooked my F22 to 9000 RPMs yo and itz fine dont tell me that!"
Right. Do it daily. Or even weekly. SOME motors may survive. I wouldn't count on it.

[wed3k]

the f22 stock camshaft* is not a revving monster.

[deevergote]

If you scrap the IABS, or just remove the butterfies and keep it as a spacer, you'll probably lose some low end... but you'll probably gain some high end by removing the restriction. Since the F22 isn't a revving monster, I'd keep them in.

[sandman61377]

you think removing the IABs completely would help with the gain? i mean having the IABs shouldnt effect the gain in the 1st place should it?

Uhh, wouldn't that be like, if you had $95 in your pocket, throwing away $5 just so the person who says they will give you enough to bring you up to $100 can give more?

[Shadow1]

Will you have a dyno in your shop? if so, DO IT!!! I'll send you a P12 if I find one!

I have a feeling the PT6 has a more aggressive map as well, so the gains probably wouldn't be 10hp. The P12 MIGHT give some power with the A6, but I don't know for sure how much of that will be canceled out by having the IABs operate on vac only (if that causes a problem, I don't know). I don't know enough to even try to assume in this case.

lol. yeah. thats one of the 1st things ill get. i think i can get one for about $3-4K. most likely ill have a couple of p12 ECUs so i can test them out on the diferent motors. and the others to sell. lol. if its a 10hp increase for swapping an ECU, SOOOOO many people in my area will want one. lol

but the question still remains tho. if the ECU isnt needed to control the IABs in the a6 IM, would the p12 still give the same gain it would give the f22a1

DAG i wish i had my shop opened. i would have been outside all night trying to dyno my car to see if this were true and test it all out. lol

[dark_stalker]

i'll look more into this
