My goal of 13s...

[toycar]

I just want to point out that the driver mod will make the biggest difference in all of these examples.


You can blame drivers for 1-1.5 sec on a 1/4 mile pass-from my experience.


As far as this thing getting into 13's, I think his 60' times should be his focus. Getting the car to hookup and actually use the power on a 1/4 mile track will be the hardest part of this guys dream.

13's are easily accomlished.

Driver mod and planting said power are his biggest issues.He will be faster on the big end, but idk if its going to be that much faster.The power potential's there with the proper parts an tune.The h2b kit alone is worth faster ets,but it cost.

he probably has a better chance doing it with the least amount of mods possible rather than adding a bunch of power. the latter will require higher driver skill due to traction issues.

.6 is A LOT of time to drop just by adding a few hp and practice. especially when you are over 3000lbs.

but go for it man. the harder you try, the better you will think on how to improve. you will come up with ideas that other people may not have considered.

How about upgrade final drive ratio. B-series run 4.7, K-series run 5.0 IIRC (don't count me exactly on it). Us H-series guys are stuck on 4.266. Upgrading to Mfactory's 4.64 or 5.02 FD would increase the torque but lose a lil top end. Not that you need to be doing 140mph+ to do 13sec

[deevergote]

The only potential issue with that is his need for daily driver status. Would shortening the gearing be too much?
Also, the engine's powerband would need to be taken into consideration with gearing changes. That goes a bit beyond my knowledge, though, so I can't really go much more into it.

i run a 5.15 in my race car

[deevergote]

I was just discussing quarter mile times in another thread, and I forgot this thread had gone to final drive ratios... I saw 5.15 and thought "WHAT?!?!"

Thanks man.

Some idea's that might free up a few hp...

Have you deleted the balance shafts on your h22?

Do you have any lightweight pulleys? Crank, Alternator, Power-steering?

What about changing to a lightweight flywheel?

Have you considered the thought of a lightweight wheel setup?

A traction bar system should help you on your 60ft times.

Bisimoto Heat Shielding Intake Manifold Gasket?

Thats all I can think of for now

[98vtec]

Do not use an aftermarket crank pulley unless its a harmonic balance like ati or fluidampr

Do you have any lightweight pulleys? Crank, Alternator, Power-steering? No sir.

What about changing to a lightweight flywheel? To much work, haha, tranny was just down for a swap, maybe when a new clutch is in order.

Have you considered the thought of a lightweight wheel setup? I have, just not sure what direction Im going. Maybe some stock 14s a buddy of mine has.

Bisimoto Heat Shielding Intake Manifold Gasket? Plan on it.

How do you feel about a 3" exhaust system?
My greddy sp2 is in pretty poor shape.

In the future the bottle may go on and a set of cams later on.
The header Im going to be running is most likely a 4-1 hotshot that I am modifying the collector to 3".

[Flatline]

definitely dont switch crank pulleys. If you spent the money on an ATI damper, id kick you in the face for not spending a $100 more for a bisi header.

[cuate01221]

It can be done, but it won't be easy. My buddy went from running 14s to a 12.4 in less than 10 minutes. All he did was mess with his timing. Then again this was a 13b carbed rotary.

3" will ultimately make more power. Make sure its mandrel bent. If you were closer I could buold you a full exhaust setup lol.

And please do not get a bisi header. The hype is not worth the outcome of a terrible midrange. Its worth your time to spend your money on proven parts like smsp or hytech. Especially when u are trying to achieve your goal. Going to a 3" collector...eh. May ne a tad big. My race car uses a 2.5" collector with a megaphone exit which tapers to 4". You are only going to hurt yourself trying to cut corners.

[deevergote]

SMSP has always been my favorite option for an H22 header.

Just... if you get a real performance header, all I ask is that you get one made by an original designer, not some knockoff of the original (there is one very popular knockoff of the HyTech header that's been going around...) Supporting the knockoffs just puts the real ones out of business, or at least makes them stop producing stuff for us. Without the innovators, we have nothing worthwhile.


I have an Unorthodox Racing crank pulley on my H22, and it's been there since 2003. I've heard of many issues regarding oil pump failure attributed to underdrive crank pulleys, but I've had no problems with my own. I'm not saying it's a good idea... but my own personal experience has been positive. When I eventually get around to building another H22, I probably won't use it again, though... just to avoid the risk.
