i give props to the f20c rx7. My friend gabe who owns T3 has a f20c ae86. I was going to finish my touge miata with a f20c swap but decided to do ls1 fc. f20c is a damn good motor. If your going to compare it stock to stock to any rotory i would rather have the f20c. I know lots about this thing and its a n/a beast. Maybe not as a drag motor but as a daily driver/mtn passer/ auto x it rules.

 

lol. so its measured on the butt dyno? we all know how accurate that is... its not.
so, whatever sounds the fastest is proclaimed the fastest... on the butt dyno.

 

For your info, the car ran in superlap time attack competition here at Hawaii Raceway park.
It ran a best of a 41.65 second lap in the short course, which puts it as fast, or faster than the modified WRX STi's there...

 

Nobody said it wouldn't be fast...it would just be cheaper and faster with an LS1.

I guess you missed the part about the free stuff...

This was never about building something FAST and CHEAP.

If you spent just 10 minutes with the car and the builder in-person, a LOT of you people posting negatively in here would all shut up.

Hey Ted, you coming out next weekend to SuperLap?
It's getting crowded now, with a lot of guys coming out for the time attack competition.

Anyways, I really doubted anyone would have been too interested in this project, outside of the few friends who knew we were building this. I am really amazed by all the attention and controversy this has brought about. But anyways, it's our car, we are having fun with it and that is all that matters. RETed knows us very well, and we just do things, for the most important reasons.
1) We are having fun
2) We could do it ourselves.

Very little of this car, went outside of the shop, and we built the car within 8 months from getting the car. To me, it took a little too long, but we had some regular dragsters to build, so getting paid came first. Maybe if we could have spent all the time we had on the car, it would be done in about 4 months.

Hmm, if I could find a cool domestic, maybe I should build a 20B and put it into something like a Monza, or Pinto. Just to irk the domestic guys.

 

Why so much hate for Honda? They make some of the best *reliable* motors out there and has been proven to work. Formula 1 should be enough proof Honda can crank out good motors. only behind Ferrari.

 

OMFG, the ignorance in this thread is amazing!

 

Someone needs to be shot....I never thought I'd see the day

 

lol. I forgot I was registered here. I would build that car just to spite the f20C rx7 haters. Thats awesome, gotta be fun on the street. I would love to see the face of an RX7 owner when I crossed over into vtec and kept wrapping to 9k.

7.1? Isnt that like low 12's high 11's in the 1/4. Oh and the only LS1 FC I saw ran 14's at the track.

 

that must have been a pretty crappy ls1 in that car; most ls1 fcs run mid to high 12's on the maiden voyage

 

Why do we get vtec dorks who obsess about high revs?

Its power to weight. Thats all that matters! Oh, and BTW, if you really wanna see how highly tuned an engine is, work out the BMEP, or look at torque per liter if youre not into doing a lot of math.

And yeah, LS1 on a 2800 lb car... if he ran a 14 he must have had REALLY bad tires or the dragstrip is fucked up... or youre a liar. Stock RX-7s run 14s

 

the only thing I can think of when he says "revs more willingly" is horsepower, because its kinda started to irratte me because people say they "measured" so and so odd horsepower when you dont measure HP at all its just a mathematical equation thats relating a bunch of factors. what you measure is torque. IIRC the equation is

(RPM*Tq)/5250

thats how you get Horsepower and we all know higher hp is better.

but i thought F1 cars still used camshafts but they did not have any valvesprings, the valving system they had was totally pnuematic and the "valvespring" was just a airshock basically.

why bash hondas? thier import cars none-the-less mazdas are imports too i think it really doesnt matter what engine goes in a car as long as it works and the owner/builder is satisfied. case in point thats why i am doing my swap of a northstar engine in my FC i know it doesnt have the loads of HP that a LS1 or LT1 has but its different and its what i want i couldnt give a rats *** what most people wanted me to do. i dont care if you think its stupid or you think its not going to work. is there something radically different you have done? have you made some change to what is considered normal around your friends or peers? i dont like conformity and normality thats why i walk the beat to a different drum.




and as a note to the poster above

stock Turbo Fcs runs 14.9-15.1, and stock NA Fcs run a bit slower around 16's IIRC. Unless that LS1 FC didnt have drag slicks or it was thier first time running i can understand a 14 second time by spinning or bogging.

and revs do count if your still making tourqe up thier

for instance say i have a cadillac ETC it makes 300 lb/ft of Tq at 4400 rpm using that equation above that gives me @ 251 hp at the same rpm. so lets say that my cadillac suddenly had @300 lb/ft of Tq at 15000rpm instead. (such as an F1 car that makes little amount of torque at a high RPM) using the same equation again that gives me @857 hp at 15,000 RPM. SO yes revs DO counts IF you are still making tourqe up thier.


And there is A LOT more to things then power to wieght

im done for the day

 

pretty cool, looks clean too. thumbsup for him NOT putting a v8 in there :P

 

Out of curiosity, why did you decide to go with a solid axle? Planning on dragging or drifting? Either way, this is pretty cool! It would be insanely fun with a supercharger!

It also makes more sense than the S2000. I mean, it's gotta be a lot more rigid, seeing as it's not convertable and it's got that nice cage. More car than an S2000 could be.

 

looks like an F20C to me. kinda pointless in my opinon but new and different is always good i guess

 

I left the rear diff in the car, just modified the arms to get the camber angle I wanted, and installed some aftermarket shocks with bearings on both ends.

Anyways, it is for drift, and all for fun. Remember, I could have put anything in there, it was just what was available at the time.

As for F1, the head design(ports) are from F1, not the actuation of the valves. A lot of what they learned from those engines, actually do make it into their production vehicles.

Anyways, gonna turbo it, with autronics. Should be fun. Although I do know the transmission might be the next weak link, so I am working on putting a Jerico in there now. Cant have fun fixing transmissions at the track...

 

i was just saying in regards to a previous statement you made about the actuation of the valves i know that the F20c borrows heavily from F1 design but i knew it didnt use the pnuematic valvesprings which i believe is how the F1 vlavespring works

ahh yes in this picture you can see the cam bearing holes so it is a pnuematic valvespring. just amazing how much engineering went into one of these babys absolutely magnificent!!
