you will be able to stick with the lpg mixer if you wanted, but would just have to run alot less hp, because getting towards the combustion conditions you are wanting to make high hp from high boost everything in the fuel mixes accross all cylinders and /ignition timing needs to be PERFECT.
i look foward to hearing what your lpg guy says, just ask him what he thinks the limit of the mixer is, you may find you will be happy with what it can produce, High hp numbers can start to become a large pain in the ass tho, as it starts to stress all the rest of the components in the drive line, so you will find once you get the engine sorted there will just be something else which needs to be changed aswell to cope, and so on and so on, plus with a road car with high hp it is really impractical like my car by the time you get into a higher gear like 3rd-4th to really let the power down you end up going so fast in such a short time its just rediculus, u end up with a track car really |

Yes, these cars do originally have an ECU, and yes, it is a very basic system but it does control cold-starts by adding fuel, and controls AFRs and timing etc. the rest of the time and it does use an O2 sensor and it can be manipulated as in any other EFI set up that utilizes an ECU with proper sensors. Read the sticky on this very topic at the top of the page. (Or here: Tuning with CIS) The only thing we are missing is a knock sensor but I'm fine with that as it's been shown many times how they will misread sounds that aren't even detonation and then pull timing when they don't need to. Thanks for the links! Regards, Eric

I think I get the point with the manifold now. I'd never looked into this prior.
I just read this article concerning wet/dry manifolds. Bit basic but that's sometimes the best way to learn http://www.kennebell.net/techinfo/gm-tech/manifold-injection.pdf Actually, this article made more sense: http://en.wikipedia.org/wiki/Nitrous edit: spoke with LPG gut this morning, he doesn't think the manifold has anything much to do with prob @ this stage. It is the fact LPG delivery is via only 1 convertor (vaporiser). It would have leaned out by not enough fuel. He has had success with mixers & says the mixing is all done within mixer ahead of throttle body so, it can't unmix, so to speak once in the inlet manifold. If he adds a 2nd convertor it should have plenty for 400rwhp. This is what I am chasing. The car will only be pushed hard occassionly but, due to all the bleedin' money/timer & bottom end parts used, it'd wanna make good figures for me to accept all this fun (not) I am taking engine to my builder also today. Cheers again guys!

We never said it would un-mix, just that the intake charge is heavier when there is fuel in it so it can't make the sudden changes in direction that air alone can which is why the trouble was in the center two cylinders because their runners are the ones that have the sharpest, most sudden turn to make into their entries. The fact that the trouble is in those center two cylinders is the smoking gun.

yea get a second vaporiser and a good tune on a dyno and she should be good to go!

maybe that's where the misunderstanding is Eric. The trouble was with no:3 & no:6 pistons. Not 3 & 4. I can understand the middle piston from what you are saying. If you hadn't of pointed that out, I would be none the wiser. But due to one of the end pistons suffering? It's too far from mixer to be the culprit.
Anyway, I'm on the right track & I owe it to you guys for your suggestions & quick clueing up. THANKS!

Pulled engine out & it's @ rebuilders now.
Also, I spoke to Auto trans specialist today concerning modding the torque convertor into a stall convertor so to make it more drivable with the turbo. I'm dropping it off later in the week so he can pull it apart & see the changes he can make. He hasn't done a Merc before so may only be able to go mild say, 1750rpm? Still would be better than stock idle. I was wanting 2500 however. Oh well. However, he's not to keen on the stock auto. Although seller stated he beefed it up a while back, only receipt I have as for an auto trans purchase, not any work done. So he's probably full a crap like with the engine? What I would appreciate knowing concerning auto is what is a good upgrade/swap for my engine? A V8 trans? Thanks guys!

Verdict from builder...........absolutely shagged! The engine has seen it's last mileage I'm afraid Block surface is so uneven no wonder head gasket kept blowing. Cylinder bores were buggered. Heaps of piston slack.
The light @ end of the tunnel though. I spoke to Merc' spares dealer/Importer here. The one I sourced the reco' head from. He has a 90' model 3.0L with just 100,000kms (60,000miles) on it! It's currently in a Merc being pulled apart fopr spares. He wanted $1500 for it (that's with taking back the reco head again) but under the condition he got to install it. $1000 for install including I guess injectors, lines, harness etc for petrol? Plus, cost of anything they found they had to replace would be extra. However, when I mentioned more clearly that he would be dealing with LPG & a turbo, & I didn't thing he would be able to get it sorted, he went quiet for couple of secs then said, you can have the engine for $1000 change over. Long motor without accessories How cool is that! Now I have a good low klm engine to start with properly & reliably. So rapped! I know EFI is the bees knees. Just the $$$$ & effort down here to get it. I'll talk to LPG guy again & see if he can source me some starter injector kit & then I'll be better informed. There's just other stuff I need to do for engineers cert' already. Will think on this thoroughly though over next few days.

My advise then is to get the long block with the intake manifold, that way u get to install and LPG inj kit. What ever you chose to do, i say stay away from wet manifold setups (unless its for an extra injector setup like RBCY's turbo setup on this forum)
ie: it supplements the total amount of fuel, and not the primary way of serving the fuel needed. If u recall old turbo setups, back in the early days of turbo charging, most started with carb suck thru setups, and most just gave up on it back then for lack of control on proper fueling.

Don't get me wrong I'm not comparing it to LPI set up but, it can work if a specialist does it using current technology. Also, using primer to alleviate cold start/back fire probs; seperate oil filter between sump oil line & turbo to protect turbo seal damage. This is extent this LPG guy goes to with installations. I just can't jusify the extra $5k needed for injection set up & Stand Alone EMS necessary bto set up injection system Also, car needs few other important things to pass engineers cert' here along with, ext system improvement; custom ext manifold I'm chasing & stall convertor mod, in order to significantly lower turbo lag as it has auto trans. Turbo compressor size/condition needs to be looked @. This & fact I need car back on road sooner than later.

Don't forget the piston oil squirters and windage tray from a M104.

I'll ask him when he rings me next week for organising delivery. Btw, engine was pulled out of salvage Merc today Also, the turbo is OK. Got it looked over by an old-schooler who knows he's stuff. He suggests it will make a respectable 450hp. it has a bit of wear but not terminal @ this stage. Considering I am using stock donor engine now, I may keep boost to 10psi, maybe 12. Have it with low & high boost perhaps. Say 6psi & 10-12? I don't want to punish this engine that is such a blessing in disguise considering the fate of the other one.

i have a spare set of oil squirters and oil windage tray, so if your guy cant supply you with them we could sort something out,
altho they do require some work and drilling into the oil gallery of the block to get to fit, it isnt hard, i had to do it to one of my m104 blocks that for some reason didnt come with oil squirters. |
