ok guys, if i gain 50-60 N/Awhp and lose about 110 lbs, how much would that affect the car? it would be waht about 255whp at just 2698 lbs. how much would that help teh car and owuld that be a very significant gain and help me reach a N/A goal of high 12's? not saying it'll get me there but how far would i be from that goal?

 

If that time slip is that important to you I will suggest you will save a lot of time and money by trading for a car better suited to the strip.

 

Well to answer your question, try google with"1/4 mile et calculator". I get this:

with 2698lbs, 255WHP at 12.788. Probably good enough for a theoretical best case.

Realistically, you're not going to get 50+ hp NA without ripping open the engine and replacing internals and all the associated stuff that goes with it. It's going to be more work than what you're other threads are asking, a lot more work. If you're up to that, more power to ya.

 

If you gain 50-60 NA whp on the F20C, you will be worshipped by all... regardless of your timeslips. The highest NA hp gains that I've seen were below 40whp.

If you're willing to spend the money to get the F20C up to 250rwhp, then you should be able to shave off more than 100lbs. A race-prepped S2000 weighs about 2400lbs. With 255rwhp and a 2400lb car, you should be well into the 12s. Don't forget to upgrade that diff.

 

well one, thanks for the support, wasn't expecting it cuz im used to h-t members bashing on ppl that have dreams or goals. second, i didn't know it was that hard to push out whp on a s2k going n/a. the k series motor is a lot better in terms of gettin power out of bolt ons and n/a setups than the s2k huh?

 

I dunno. Have you seen a K-series putting down 250whp? The K20 has a lot of similarities to the F20C, with regards to displacement, flow, and rev-capabilities. Granted, it starts at a lower baseline because the stock plumbing is more restrictive than that of the S2000, so it is easier to get large gains with simple bolt-ons. However, I will only be impressed with the mod-ability of the K20 when I've seen one that surpasses the F20C with NA mods.

 

lol, 250hp K20's?

They surpassed the 300whp mark, N/A more than a year ago. Not alot of R&D on the F20 in comparison to most Honda motors, it's obvious that not alot of race teams, drivers or aftermarket manufactures really care too much

 

Hmm... I should've been more specific. 250whp streetable NA K20s. Maybe they're out there and I don't know about them, but I haven't heard too much about them.

You're definitely right, though... there is a lot more aftermarket development money for the K20 than for the F20. The S2000 just isn't a particularly great platform for the type of racing that tends to lead to this type of development (i.e., drag racing). And the F20 doesn't really drop in to any platforms that are popular for drag-racing. The K20 can be "easily" transplanted into a lot of other popular FWD drag-racing platforms.

Plus, the fact that the K20 is a higher volume engine than the F20 means that there is more demand for aftermarket goodies, and people are more willing to mod them and break them because they know it will be cheaper/easier to get a replacement motor.

 

I'd love to know what's been done to a K20 to get 300whp N/A. That's nearly 100 lb-ft of torque per liter. F1 engines get about that.
