4agte power, 11.4sec 1/4mile!

It's strange, but as I was looking over AE86s in the last few months I came to realise how common (MORE common) it was to find one with some fettling of the 4age, not just the gze either.

I guess the MR2 lot are more conservative than we thought. Well, apart from some outright nutters (you/we know who you/we are ).

[Bender Unit]

Its very unsual to see your average AE86 that dosnt have one or more of the following a 4 branch manifold, filter, lightweight FW, cams, leads, ITBS

Given how overpriced the base cars are I think it's reasonable to assume that AE86 owners have typically the kind of people who have got more money to throw at their cars, whereas the mk1 tends to attract the more budget conscious who don't necessarily see cams as being particularly cost effective..

Couldnt be further from the truth, quite a few AE86 owners are tight asses and just dont want to spend the big bucks. Truth is to do this stuff dosnt take big money, the parts are readily available.

Its cheaper to tune a AW11 than it is an AE86 - at least you dont have gearbox / drive shaft issues that the 86 does.

I think Toni is right the MR2 crowd as a whole are very conservative when it comes to tuning.

[crazybrightman]

i think you have to factor in the fact the mr2 is often only owned for a summer or 2 for some cheap fun then sold on so theres no point investing alot of money in the car. also they are cheap so the cost upgrading far out weighs the cars value, and more importantly rust! if your going to spend good money modifying a car you dont want to start with a tickng time bomb, which when it comes to rust all mr2's are a matter of when not if.

[tonigmr2]

I just think it is the drifting culture vs. the two-seater nippy car culture actually. Most people with a MK1 are just happy with it as it is perhaps!

It’s quite unusual to see an import AE86 without some form of tuning, so I think it’s got more to do with where the car has come from rather than the “car culture” its not like all AE86’s are used for drifting. If you started shopping for AW11’s in Japan you would probably find lots of them also have tuning to the 4age or have SC / 20v swaps etc.

The UK is genuinely behind places like the US and Japan when it comes to tuning – most likely as they are more willing to spend the money on chasing performance and break from the norm and spend good money doing so and trying different things.

[tonigmr2]

No argument on the UK not tuning as much - but I have shopped for AW11s in Japan (quite a lot ) and I have never seen many with any tuning on other than bigger pulleys on the SC'd models. So I don't think it is just a UK phenomena.

thats had some money spent on it

[pistol pete]

big powered SC's can be done was recently rolling roaded and got 228 at the rear wheels (not my car anymore owned by the guy that built it) he has p[layed with it more since he had it off me

the only thing its was waiting for for more power was a bigger SC or a turbo change





big valves






sorry picture whore

its was a fun and very fast car




good luck to all those doing it keeping a close eye on your results

i got meslef another mk1 now... trying to decide what route to go with that

i see your project is coming along well!
how come you went for the top mount turbo? as it looks like you have had to do a bit of bulkhead cutting!

is it me or has that sc got 5valve pistons?

yeah it has.... they were forged ones for the 20v engine.. machine and work a treat
don't ask all the tech questions behind it i just know it worked

[crazybrightman]

hold on i just read that again 228bhp at the wheels! thats a good 250-260bhp at the fly!
surely thats not on the standard supercharger i thought they couldn't flow any more air than 190bhp?

I keep on asking to see a dyno plot for it everytime the topic of that car comes up, I have yet to see one. Even on the supercharger forum I searched on the car and found the thread but no dyno plot. that kind of bhp on a std intercooler is interesting, especially also a std sc12 eats itself at 12'000 rpm (manufacturers figures)

Without a duno plot, bhp figures are meaningless. I.e

I got 200bhp from my 4age, it was dynod so I know its true.

I do think it has a lot of torque and a healthy amount of power, but not 228 atw. hopefuly I can be proved wrong with a dyno plot

[010on1986]

there was a "japanese magazine" feature of the car. I would scan (pdf) and post but wouldn't want to get copyright issues.


I think it mentioned a backwarded calc of 228bhp and 165hp atw. (which is rather healthy considering the std is 145hp at the FW)

If it was 165atw, 228atf, then they are calculating based on around a 27% transmission losses. Isn't that awfully high for 2wd vehicle.

[crazybrightman]

yes it is more like 10% for a very good transmition maybe up to 15% if its on its way out.
at the end of the day the only figure that realy matters is the atw figure as thats all that your getting to move you along!

i also remember the article now i think about it and im sure it mentioned it also had some head work and larger valves which i thought was as im sure the standard head and valves are good for 180bhp or so. so seems odd you would need to do them on a forced induction engine.

i keep bloody going over this worth you......
look at teh pics if you think that is a standard intercooler then there is something wrong with ya matey....
believe me you have no idea how much went into that engine.... and the set up i do not understand it fully but then i never built it...
when i had the car is went ont the rollers and got 168hp at the wheels on standard dizzy and \ecu and could not go above 5k due to that ( i have the print out around here somewhere but no scanner
)......
it is now with the guy who built it i no longer own it.. i only went on the rollers about 5 weeks ago and the builder does not do forums etc so doubt you will see the print out.. but why do you have this obsesion of putting this car down???????
i have no idea what your problem is. ask the the people who have seen / been in the car (most in the south east)

i have no ties with the car now and could not care if it produce 10hp i just get wound up with people putting down a car they know nothing about.

the car has now been running for for 2 1/2 years with out issue as far as i am aware

if you do want to know more about the car and the specs etc and proof of the power i know the owner will more that happily talk about it
01233646494
www.tracart.co.uk
his name is Zeca

if you so desperatly after proof, there ay go feel free to find it if you doubt everything so much..

sorry to rant i just know how much went into this car for me and what outcome i did eventually get. sorry i have no means to prove it to you but the builder with the car happily will

pete

[cartledge_uk]

I only doubt bhp figures without dynos.


I don't have an obsession with putting it down, I just want to know what power it made (with proof) as I'm very intersted in how they got it from the std sc unit.

As I said above

hopefully i'll be proved wrong with a dyno plot

Thats hardly putting it down.

Japanese Performance Magazine May 06 Issue 64 page 95 (I just love car boots for old magazines £1 for 5 issues).

Para 3 Estimated 223bhp.
Para 4 "but that was 223hp at the flywheel ..............horsepower at the wheels (at this point 168bhp)" blah blah blah.

later in the article (last para page 97) it mentions 168bhp and 153lb torque ATW measured on rolling road at CPL racing..............

yep thats correct they saw the current dyno plot at that time

at the time it went on the rollers it had standard ECU as said above and it was seriously detonnating (blew the head gasket) and did not get above 5K ish due to the standard ECU
it the went off the road had a lot more mods including the ECU and coil packs etc etc AFM removed

as for the valves they are from a supra TWinT the head had a lot if work done to it..
after all work done it was road mapped by preffesional who work and tunes engines everyday. was estimated 230-250HP at the fly...
that was how it left me
it has now had some more work done to it since then and been rolloing roaded but as said i not the owner so do no have the dyno plot... but next time i see him i will point him in this direction
