Haha, not much that way though There are other options however...

The SC is defineately the best HP bang for the buck. I'm staying NA and I hope to see 285 to 300 at the crank some day, but it will be very expensive. After the CAI, 70mm TB, header, exhaust and ECU you've got $5300 for the first 15 hp gain ($350 per horse). It still has to be determined what head work will render, but my guess is 15 hp with cams, valves, valve springs and gasket costing roughly $4000 with labor or $266 per horse. Lower end work with high compression pistons could add another 15 hp for yet another $5000 parts and labor or $333 per horse. This would bring the NA HP average to $317 per pony. This is 600% more costly than the $50 per horse average of the SC, while it should extend more longevity and broader response throughout the RPM range. I believe Derryck is getting over 400 hp from an $8K investment in Turbo Charging, or $50 per hp. It all depends what type of engine, engine response, durability and budget you personally prefer. Each application, including stock, is correct for different individuals.

Plus $2500 for a new differential

Sorry Wesmaster

I don't think you can directly attribute a differential failure to the SC, more so maybe to numerous aggressive clutch drops.

Drop Top

I think if you get a SC, you're probably gonna be dropping the clutch more also. So, I think diffs would be a good idea. Just a thought.

You're probably right, in fact, it is probably good to do the flywheel, clutch and bearing caps but, you can't figure it into your cost per hp any more than coilovers, because it has a different purpose.

OK, I am going to stir up the pot... muddy the waters.. or whatever.. I also wanted to put in the disclaimer that I am not a specialist, but I did stay at a holiday inn express last night.

First of all, in summary, that SC blows donkey balls. However, if all you want is a quick boost of high end HP then sure, go ahead.. I wouldn't plan on doing much else besides that..

The SC sucks because ..

1) It doesnt do that much on top end (real world - 3rd party tests only show 80 hp increase)
2) Doesnt do anything at low end because of the way the pulley system is setup. This apparently was done on purpose as there were tuning/detonation problems with low end boost.
3) Not as reliable as an N/A setup
4) Once you have the S/C on there, other modifications don't seem to help that much, or even decrease performance.

An N/A setup is going to be way better because power will be delivers more naturally (no spooling boost.) The F20C seems to only need just a little bit more (30 ft lbs?) of torque at low RPMs to make the engine more normal (ie, power below VTEC.)

This can be done by an increase in compression, a better flowing head (there are porters out there that have already worked on the F20C) lighter pistons, different valves.... basically a spoon spec engine. It will cost around 12000-15000 or so for a head porting, and spoon internals (including ECU, headers, and exhaust) and you will have a Viper killer.. And you will be smoking, absolutely smoking anyone with an S/C ..

My advice is to go N/A, or wait for another boost option, which WILL happen given time.. From what I understand the largest hurdle for boost at this point is the ECU programming/tuning. The best way to boost this car includes a new computer which costs a considerable amount of money. (or wait until stock ECU's can be reprogrammed..)

Also, to the guy who was talking about the S/C boost upgrade, from what I understand that is a bunch of crap and that there are no plans for the upgrade.

You can have a pulley fabricated for about 200 bucks or so, but you will have to do some math to figure out how much boost you want. Also, you can't upgrade the boost with out a custom (front mount?) intercooler. The Comptech S/C puts so much hot air in to the F20C I wonder why they don't blow up immediatly..

There is a company in New York called Denko Performance who will make a FMI kit for you for aroudn 2K, and claims 30hp gains.

OK, those are my thoughts..

Bye

While I agree with you and am a NA fan, I believe the thread was how do I get more HP and not which HP is best. Play nice with the other kids!
