How fast is a 86 with 20V?

[robokill]

i have driven in the passenger seat of E10 with silvertop and the TE71 blacktop from my friend is on the road i also know of an E9 with a blacktop which isn't modified but with the right ecu you can put it out to 180-190 bhp on the crank

the silvertop is afm and so has a disadvantage the map sensored blacktop beats the vtec without trouble

never go for a silvertop if going for a 20v go for black its map sensored and can put out much higher than the silvertop

Once again.. there is no way in hell that a stock black or silvertop will put out anywhere near 180 bhp. The stock ECU is already tuned within 95% of the engines capability and is better configured than a experienced engine tuner using a standalone motec or better ecu could ever dream of achieving. Emissions testing is NOT done at wide open throttle! So thats NOT a limiting factor.
Claiming 30 extra horsepower from just a piggyback is not smart and indicates a lack of knowledge on even the most basic forms of engine tuning.

Edit: maybe this is a better way of formulating things..still stand behind some of the statements so I left those alone,.,.

[Jan Pedersen]

Easy now guys! No need to get personal!

With that said... I think 190 hp sound like a lot, but I know a guy who claims to have 185 hp on a std blacktop. Im not sure if its true though - I sure would like to see a dyno plot!

Do anyone know what a blacktop costs in your countries?

Figures usually mean squat anyways because in many situation they are just seat of the pants gambles at HP.

THat said, any engine can be tuned to a zillion hp, its just a question of how long it takes before the damn thing blows up

[NoHachi]

Trust me..its not true. The cams on the 20V are just to mild for these kinds of performance numbers..Maybe a 20V running at 5 psi boost could achieve them.
People can claim al they want..usually they feel a need to justify the massive investment they just made.

[EDIT] I got tired of this and calculated the maximum horsepower that can be supported by the 20V's 295cc injectors. This would be around 180bhp, so anyone claiming more than this on a tsock engine and stock fuel pressure has a magic engine on his hands.

Hehehe, nice when you have those sorta tools at hand and the knowledge to use it

I think you're getting a bit to much into this man, people always claim the weirdest things, sometimes they've found something you haven't heard of, often they are just exaturating. I know I do that last thing all the time You need to value those remarks for what they are worth, not for what they say literaly. So a 20V probably can be tuned to be a nice potent engine, even if it doesn't reach over 180hp it can still feel like it. Maybe it does catch up or has caught up to a CRX, maybe thats just due to driver skill difference.

Interesting subject.

My silvertop makes 180(ish) bhp if I believe the dyno sheet that came with the car from Japan. Its had quite a lot to make that power (ribbed block, crank, rods, pistons, head work, valve work, cams, adjustable pulleys, injectors, ITBs, tubular manifold). It feels brisker than the other hachis I've driven - but I've never driven a standard one.

I think though mapping alone its hard to get big gains from little engines without changin a fair bit. Now if you are running a blower... thats a different story I guess.

My good friend dingy (has a completely mental 450+bhp cossie powered mk2 ford escort) happens to have a CRX parked on his drive - I wonder if an experiment is in order

Guys..lets see here regarding 0-100 times / 201m & 42m times

8,9sec is accurate from the factory specs

My ae86 GT-S -86 did 90% stock with 15" 195/45-15 tires full interiour & just the twin carbon exhausts as mods.

9,1sec with a dragracestart - (dumped clutch @ 7000 rpm) perhaps 2 meters wheelspin & then the wheels gripped perfectly.

My car reached the following speeds...

topspeed @ 201m was 11.1 - 111km/h
topspeed @ 402m was 17,1 - 139 km/h
60 foot times were 1,9 sec - very good for such a slow & underpowered car.

the few times i have streetraced the ae86 i have beaten SEVERAL turbocars in the first 100 meters... hehehe

This was 2 months after i got the car in 2003.

This year new tests were done...

46 km/h in first gear @ shiftingpoint 9100 rpm.
88 km/h in second gear @ 8950 rpm.
137 km/h in third gear @ 8850 rpm

0-100 was down to 8,2 sec
201, was @ 10,1 @ 114 km/h
402m was @ 16,1 @ 144 km/h

The mods done to the car you all already know.
lightened - 860 kgs, stock 4-age t-vis large port engine
remowed t-vis, open air filters, 2" exhaust with just a BIG
japstyle muffler & the TRD highrise headers.

So - there you have it in black & white guys

My car will do (spedometerspeed) 177/178 in fourth gear
& 217/218 in fifth gear @ 8700 rpm

regarding the high revs - my AUTOMETER revcounter´s shiftlight is set @
8700 rpm.

good one making that much on a 16v i wonder what the bhp output would be.

Nevermind regarding the topic about 20v caus you can only judge when seeing/riding one

the standard ae86 will get left far behind racing a 20v e10 so i still think the vtec crx isn't that fast

[Ivan141]

Why do you keep comparing it to a VTEC crx? Just because a 20v ae101 is faster than an ae86? I cant claim to have ever experienced a vtec's acceleration, but a simple 1.6 16v DOHC crx engine is very similar to the bigport 4age in output (probably a bit more powerfull, a bit less rev-happy). You've seen what it takes to make 180hp from a 20v.
A stock vtec crx in good shape does around 135hp to the wheels with a manual gearbox. Here's a lil quote I found about power at the wheels on a 20v:

Quote:someone posts about their '96 rolla with 20v is making 101whp and complains.....the almighty bill sherwood replies and says "That's about right at the wheels for a 20v. Nothing to worry about

Now if Bill says that's correct, I think it would be fair to assume that the B16A would whoop the 20v. And I'm not a big honda lover or anything, just want to stay realistic in these matters.
