... We will find out Tuesday to see if I've managed it. I loaded the new engine map on before and wow does it fly now. Will speak to A&M Conversions in Deeside to try and book a rolling road slot in on Tuesday.
Fingers crossed!
-
Replaced it with a V6 ...... ? ::) ::) ::) ::) ;)
-
140bhp to 200bhp from an engine map? To say I'm sceptical is an understatement. But having a 2.2 myself (be it off the road) I'm happy to be proved wrong! :)
-
Unless its had a lot of engine mods or a turbo fitted a remap won't give you 200bhp unfortunately, you might get another 10% or so

With a supercharger bolted on ....sorted :y

A few other things have been done too - ported and polished inlet manifold and throttle body, fuel pressure raised and a smoother flowing exhaust. It last made 181bhp on the rolling road on a stuffy hot day.
-
Still can't believe those figures, not with such light mods. The Z22YH which was direct injection did 153bhp out of the factory

Take it too 2 or 3 other rolling roads & take the average, bet you will get different results
-
You will get different results, you'd get a different result on every single rolling road you took it too, however, this one said he had 180.9 BHP so he did make pretty much 181 BHP :y. That's an absolute cracking figure without a turbo on that engine!

I don't agree. The rolling road says it reached almost 181 BHP but who says the rolling road is correct. Its common knowledge that rolling roads are often set to show greater output ::)
-
There are a few astra 2.2's on the forum running around 190bhp :y. With the modifications on mine its running approximately 155 bhp.

Astra 2.2 lump though is totaly different engine :y

I did think the heads were a bit different but I was assuming they would be the same. Wrong again ;D

Ah its running well now mate.
-
honestly 140 hp to 180 from an athmospheric engine doesnt seem that easy..lots of mods to do and most critical being high degree cams and both inlets and exhaust modification must be done ... :-\
-
Are they 144 or 147 bhp standard?
-
In the Omega 144

Cheers tunnie. Think its 147 in the astra then.
-
I see this has become quite the controversial thread! :-\
-
Is this power RWHP or fly wheel? Most Euro manufactures give fly wheel figures when the sell cars. It bigs them up more.
US manufactures are the opposite & give RWHP.
-

You started it ;D
It's good that you've done something from the norm. My hat's off to you :y :y
-
I too am sceptical about how "generous" the RR is, but either way it's clear you're doing a lot of work and mods and you're enjoying it :y :y
Make sure you let us know the outcome ;)

Cheers guys.
Flywheel power. As said, the bigger number looks better. The 180.9BHP should be pretty bang on. That run was on a rolling road day organised by another forum where all the cars were running pretty much what was expected. I've sent the engine map file off again to have a little flat spot between 3 and 4 thousand revs sorted. Feels like the car backs off slightly but past 4k it's off like a rocket again. I'll load that back to the car later and see how that goes. Seems very very few people have mapped the Z22XE engine!

Yes good on you mate , looks like you are happy enough with what your doing so each to there own 8)

That won't do much, as the injectors are plenty big enough :)

Can't disagree with that :y
Personally sceptical that the RR figures are correct, a 30+% increase in power is a big ask from modest mods.
-
I wasn't taking the pish :(
I can't fault anyone who spends money and more importantly time improving their cars :y
-
New map is on the car and we have no more flat spot between 3k and 4k revs. Be interesting to see what this does to the fuel economy.

Bugger, left it too long to edit the post but the rolling road has been booked for 11:30 tomorrow.

To get the RR figure into perspective, did you do a run (on the same RR) before you started the mods to the engine ?
-
Not read the full post.
At what revs did you get your peak power at ?

Yes, this is a vital step. Whilst you can't really rely on the power figures from all rolling roads, for a back-to-back test to see what you've achieved they are useful.
It's important to use a rolling road other than that owned by the bloke who tuned your engine. ;)

It would have to be close to 7K RPM in my book, hence I'm sceptical that standard cams would achieve it, as the 2.2's cams feel quite mild.
-
Am I right in thinking that the 2.2 is pretty much the same as the 2.0 ecotech but with a different crank for a longer stroke hence the extra 200 cc's ?
Iirc, you can get 200 bhp out of a redtop but thats with fancy cams and other bits :-\
Anyway, fare play to the OP for having a go :y :y

Yep, similar engine and they make about 165 on standard internals and Weber 45DCOEs IIRC.

Similar engine but a more compromised head design (sadly).
Although at the higher powers you realy need to stud the bottom end.
There are one or two of the red tops making high 200's bhp after major expense!

Is that the engine that was used in the Cavalier british touring car during the 80's ?
-

I have seen one (after major expense) make 302 on Dave Walker's rolling road. No moving parts original, and the rev limit was tweaked to a slightly naughty level to get the money shot, as it made slightly below 300 with a sensible rev limit, but was still rising. ;D
It peaked somewhere between 8500 and 9000 IIRC. ;D

Been and run. Going back on Thursday after a fuel filter change and taking the mapping equipment with me. Got a good run on gas but not as good on petrol. We did the petrol run first and it kept running lean at much more than 4 thousand revs. Way down on the 181 it made before. The gas run went well though. 160.9bhp and 150.8ft/lbs at the red line.
Something isn't right on the petrol side so I'll map the car back to standard, run on the dyno then stick the map file back on. Then we'll at least know if it's a duff map or not. I'm hoping it's just a blocked fuel filter. It was done about 30,000 miles ago but it's always run on the dregs of the tank and has had injector cleaner through it god knows how many times.
-
Keep us posted as to the ins & outs :) :)
I hope you achieve a good result :y :y
-
The map is off the car, back running the standard map now. We believe that the gearbox ECU is holding it back because the gearbox ECU is seeing too much torque - making it think that something's wrong. Manual conversion it seems if I want to go any further, even though it's not close to the AR25 limit, the software doesn't like it.
