There was no carbureted Escort in 89. Not much you can do about the rev limiter unless you can get the computer reprogrammed. Its there for a reason and there isn't any gain to be had in revving higher with that engine.

If you go to the 1st Gen thread there is a load of information about your car there
most of the things you will need for your 89 will be in the first few stickies
as to the rev limmitor it is built into the ECU and you will have to swap it out
for a different one from a merkeru to change that

Hope that helps

and if i am wrong please correct me folks

Why is it that people think if you rev a motor higher it will make more horsepower? They can't and don't and all the extra rpm do is abuse the motor. Removing the rev limiter will not give your engine the horsepower of the GT's HO motor. The CFI motor has 90 horsepower at 4600 rpm and the HO (GT) has 110 at 5400. The reason for the difference is not rpm, it is cam, fuel injection system, etc. Revving more than a couple of hundred RPM past peak horsepower nets your LESS horsepower. It's called a horsepower curve for a reason. :roll:

I agree, after peak HP, increasing the RPM's goes to the DOWN side of HP, although a LITTLE is aok, but NOT past recmd redline for sure.

So I 'm not a part of the debate, my question is academic. Has anybody ever seen a published HP or TORQUE curve for our Gen 2 1.9's?

thx,

No, the WHOLE curve

for the 2nd gen 1.9's it's [email protected] and 108 ft [email protected]

was that the info u wanted larry?
If ya read Hot Rod magazines, etc you often find a curve/chart that gives you the HP and/or Torque at EVERY RPM.

Thanks for the info, but I'm familiar with the "rated" HP and Torque that prob came wtih the advertising literature when the cars came out.

Yip, I'm aware of that, and also when those 1.8's chime in and show their better performance, yip, I know.

So, I'm talking about the WHOLE curve. If you havn't seen one, I'll try to dig one up for you, although it might be on a 390 Ford/Mercury FE block, ha.

Or, ummmm, 427 Ford/Merc.............

Seriously, I'll see if I can find one, but I've NOT seen one for our fave Escorts.

I guess I wasn't very clear, what the hell has that question have to do with the op's original question for this thread and why does he just go look like the rest of us do?

Apologies from me

I wasn't clear either; didn't mean to hijack, but we ALL make mistakes; including the guy that stated the subject car is a 1988; no, it's a 1989.

Now MY question was to reinforce Beard guys comment on "increasing the rpms DROPS the hp".............. which led to MY erroneous Gen 2 question of a HP/Torque curve, which is an error on my part because 1989 is Gen ONE..... and ooops, the Gen ONE has 1.9 L and so does Gen TWO, and so my question tho worded WRONG was still the RIGHT questions.

Ummm, whay is that other guy so sensitive; I'm talking about the "1988" guy?

Let's have the spirit of FUN,

Sorry for my apparent "intrusion".

[Edit; ha, I made a DOUBLE mistake; the guy I was REINFORCING AND AGREEING with is the guy criticizing me; I'm REALLY mixed up]

Ok well the car is an 89 and it is carburated so the first guy obviously knows nothing about cars considering i own it and drive it i know what it has and the reason i am wanting it to rev higher is because i race it at a dirt track and i am having to shift to 3rd gear because it hits the limiter and i only need a few more rpms to prevent this

Unless you or someone else has modified it, it doesn't have a carb. Just as has been said before an '89 Escort wasn't made with a carb. It may be throttle body injected which kind of resembles a carb, but they are two totally different things. I think the last of the carbed Escorts were made in '86 unless I'm mistaken. I own 2 '88's and both of them are throttle body injected as were the '87's.

I knew they weren't carburated because my dad had an 89 LX and it was CFI.

There's a serious flaw in this entire thread: 1st gens have no rev limit pre-programmed into the ECU. There will be a mechanical limit, however.

If you're racing a CFI ('89 LX) then you've got the small intake, small port/small valve head with the weak cam and small exhaust. Just doing a gasket matching on the intake side, polishing the exhaust side, switching out the LX cam for the HO, and giving an HO header will free up some power, take off weight, and make the car more responsive. It's about the best you'll get without an HO engine. You can also install a different model MTX to have different gearing to work with the engine RPM better.

FYI: peak power for the '89 (roller cam) is spec'd as 90 hp @ 4600 rpm, with torque being 106 lb. ft. @ 3400. After 5000 the engine falls on its face entirely, so a better cam at least is in order.

can't u just swap the head and intake? i'd rather have bigger intake ports, valves, better cam and combustion chamber all in one swoop.

To swap heads would require rewiring the injector setup at the very least and running a Tempo ECU (minor pin swapping required as well), along with installing HO pistons to match the hemi head, otherwise he'll have low compression, which will definitely affect performance in a race. He'll likely have more power, but probably about as much as just running the HO cam and exhaust on the CFI with the minor head/intake work.
