Safc with silvertop?

[trueno_20v]

Im looking at getting a safc for my trueno (silvertop 4age) just wondering if anyone has had one tuned on there 20v and if its worth it and what sort of power gains do you get? Atm i have extractors, exhaust and intake.

[sergei]

well, actually I have not had it "proffesionally" tuned, but from my experience if it only sit there (all settings are at 0, meaning that it has no effect), my quarter mile time was worse then when I completely unpluged it! Also no matter what I set in there did not had much effect, and result on dyno was less then without, I've to set it to have ~13 to 1 ratio, and still no gain what so ever, I also tried richer and leaner (12 and 14 to 1), In fact as it sat there at best I lost probably about 2kw (marginal but still). But my silver top at that stage was not completely stock...
"Performance" mods where when I had SAFC:
Cold air intake (from bumper)
Apexi 4to1 extractors
2 1/4 exhaust
Black top cams
Mine's ECU

At the end I just sold it, infact when I got rid of it I got better fuel economy (extra 50-70k out of tank), more torque down low and got rid of that 3800rpm flat spot. I had it for over a year...

Ohok and what sort of power was that motor making and 1/4 mile times???????

[sergei]

my best time was 16 flat thats including all the stuff in the boot (subs and amps) and my very slow shifts .. best power was 70kw at the wheels (done @ shore performance )

trap speed?

[sergei]

rt 0.141 et 16.00 134kph
thats from memory, I'll have to find the slips to see 60ft time...

[trueno_20v]

Thats weird for your power and trap speeds with all those mods ecu etc, my car only has exhaust extractors and intake pipe and im doing 16 flats @ 87-88mph (about 145k?) with sh*t launches..

[sergei]

thats why I bought GT4... Too much money spent without any results..
my AE101 has:
Mine's ECU (9000rpm rev limiter)
Blacktop cams
Blacktop trumpets/plenium
Apexi 4in1
CAI
2-1/4 exhaust
Oil cooler
4 puck Exedy clutch
6 speed BZR box
and something else that I forgot...

End reslut is that is fun to drive it, but my ST165 is way more enjoyable and faster for same money...
20valves are overrated! (both from Toyota and general public)
I don't like hondas but B16 will kick 20v ass anytime.
Toyota did a big mistake by putting 150Hp motor in a FWD 1250Kg car and put a GT badge on it!

[RomanV]

Wow, they arent that heavy, are they?

[Mr Revhead]

not usually!

are you sure there wasnt something wrong with yours sergei?

[gazza_jay]

well if my car weighs that much and the small mods Ive done hell I think I got a rocket 4 a 1600 lol that means their must be slow hondas... seriously they cant be that heavy.. and i seen a safc of a blacktop and I seen he has got some good gains everywhere..

[trueno_20v]

i wieghed mine it was 1060.

[sergei]

I'm sure there is nothing wrong with mine, it probably had cambelt off 5 times (3 new cambelts), so that is not timing issue, it measured 14bar in each cylinder before i did dyno, tried different ECU (still slow POS). As I said I gave up, as poured money into it without getting any gains. Last time when I checked they where 1150kg dry. So to add rubbish and petrol and driver it is going to be near 1300kg..

[Mr Revhead]

maybe someone poured lead into the chassis rails!
i no if mine did a 16 flat as it is now id be uner the bonnet looking for the problem

but yeah they arnt fast cars, but they are fast for what they are

[sergei]

Come to think of it I'll give it a try on next after next night drags (as on first one I'll be taking my GT4)

The catch cry of slow car owners everywhere!

B16A's are fast for what they are. 20V's were asleep when the car gods were handing out go faster pills.


Theres a silvertop down here who came out the the drags a few times, ran 16 flat consistently, made a proper cold air box up and it dropped to consistent 15.5's. Worth looking at.

ON the topic at hand, I'd say the s-afc had no effect on your car sergei since the mines ECU had already done all the fine tuning you could get away with. On a stock ECU and slightly modified car, there's sure to be gains to be had with some fuel tinkering.

[Mr Revhead]

are the b16as the vtec ones?

no not a catch cry.... i mean what 1600cc car really is fast in the broad scheme of things? if you compare them to ferraris then they are slow.... compare them to 1600ccs then they are fast, the only thing the hondas have over them is weight, or lack of it. they are close enough that the driver is more important

ppl who say 20vs are crap are just ignorant

[RomanV]

I can vouch for the fact that a well driven blacktop has a bit of go.

Ive driven a silvertop in an FXGT with intake/exhaust, it seemed to go rather well, but nothing overly amazing.

But when it comes to NA and small engine performance, honda = win.
The toyota motors are good, but the honda engines are just better, and respond far better to mods.

[EVL GSXR]

They are Crap I would take an old skool Red or Blue Top 4AGE over a 20V anyday.. And yes Honda's are abit lighter but there engine in general own's a 20V end of story..

[Mr Revhead]

its not as clear cut as that

when talking mods then vtec is negated as you can alter cams in the toyotas. easier to get a broader power band with vtec though.
when your talking mods theres no real advantage to either... but theres way more toyotas in racing.....

but you gotta be fair.... no point comparing an ae101 to a 96 civic....
a fair comparison is the 89-93 (?) integra with 1600 vtec, in that example the ae101 is the better car.
