macka'sxr6t

This interesting reading. My son is going to turbo his EL 4lt. We've just purchased an XR6 turbo for it. Is their anyone that maked a good exhaust manifold for the 4lt similar to the one in Rapid's pics macka

Adam is it possible to fit the premium ICC into my ute and what is involved and approx cost. And source of parts at a reasonable price macka

No Tab the family decided to stay in Vic. We have moved though to Mildura just after xmas. Been busy relocating and get my business up and running.

Hi Guy's, I Finally get back to see whats been going on. And boy looks like things have changed. I can see that it's going to take a while to get used to the new layout and some seriously late nights of reading to catch up on all the goss. macka

Its Mackas son here, Im on the P plates I have heaps of trouble not attracting the cops, because of the shaker...

Oh? Do you remember who did it? What do you mean by 'burst'? ← That would be me macka

Hi Rapid, Good to see you thinking outside the square. I'm sorry to be the one to burst your bubble. But I tried that 2 years ago and it failed. You will end up going back to your original design which I also did 2 years ago. <div class='bbimg'><div class='bbimg'> </div></div>I'm not trying to be a smart arse . So I'll tell you the areas that will let you down with the N/A setup. Firstly you will find the factory rubber seal will pop and leak boost pressure if your running anymore than 8 psi. It is only glued to the plastic resonator. Secondly you will also find that the metal plumbing will keep working it's way loose from the other end and keep popping out. This can be very embarasing if it comes of at the wrong time and you have your arse handed to you when you have no boost. It will also leave a little pimple in your bonnet. It comes apart with a bang That is why I made this one up and bolted it to the factory plenum using existing holes. <div class='bbimg'><div class='bbimg'> </div></div>If you don't believe me, keep flooring it in second or third gear from low speed making the turbo boost hard under heavy load conditions with your high boost map. You will eventually hear a little pop from under the bonnet. You will then notice a drop in performance. Much better reliablilty using you metal setup macka

Nicw work Eugene keep us posted on any noticeable gains

Any pics of the finished project

That's archaic Macka.... Wait till you see what we ( gramps- I pinched it ) have got planned.. ← Look forward to seeing what you have planned I hope it provides the results you seek. Are you going to use a larger throttle body? I don't see the benefit of using larger than 3" unless you are. Look forward to being proven wrong

You can fit a 3" pipe by entering it the same way as the N/A intake. I've been running one for some time now.

As one of the few people to actually have used the EMS on a BA turbo, I would like to add my experiences using it. Pro's Does it make good power? most certainly yes. I'm yet to see many if any other tuned cars make 300rwkw using only 10psi of boost. Most people that show their dyno sheets making this power level are usually running 12-13 psi or higher. I have been in several edit tuned cars making same power and they seem sluggish in comparison. Fuel consumption for an engine producing this kind of power was fantastic. 780 km per tank of actual highway cruising. I was achieving the same fuel economy running more boost and larger injectors as I do now driving the car in stock trim. Open road cruising the engine ran beautifully. Throttle response was instant. I like the fact that can hook up a laptop and a wideband O2 sensor head out to the road data log it and make small changes to the tune yourself if you wish. No need to worry yourself with torque tags the system basically bypasses it and your engine is producing it's full potential. Cons Transmittions definately need upgrading to accomodate the high torque levels Cold starts were the only real issue that I can say the system had. This can be solved simply though with some more time spent on the calabration tables and using the EMS to run the fuel pump. Summary I will fit the system back on again one day, but for now I'm going to use it on another project I'm working on. macka

Farout, not even 2inches... is there room to sqeeze a bigger pipe in? ← The biggest pipe that I've been able to get under the battery tray with out bashing and cutting anything is 65mm outside dia. 63 inside dia. It's a very tight squeeze but it will go. Or you take another path and fit 3" macka

about 45mm inside dia macka

I don't see how the bigger IC would effect A/F ratios. Rather, I would think that the bigger IC would improve the spooling and response of the turbo by reducing restriction. ECU maybe more likely to go into over boost limp mode because of the turbo spooling quicker. macka

Mate just done some basic calcs from your graph. @ 2500 rpm you have approx 490 nm of torque It would be good to see the look on the Expensive Daewoo boy's faces when they've been blown away by an N/A xr6 macka

Mate, just found a hp to kw converter. You 5 psi 249 hp dyno run equalls a smidge over 186 rwkw. You 269 hp equalls a little over 200 rwkw. this should give something to use to work out your torque using the formulae I gave you. Excellent results IMOP. They equal some of the strongest readings I've heard about. Is your car a manual or auto? macka

Cooler looks good from the front what type is it? The factory plastic and rubber inake is holding up OK. Have you any plans to alter it? I would like to see the pod filter tucked away out of sight under the battery at some stage. Just to tidy up the engine bay. But that's just my OP pls don't take offence macka

pic, might not have uploaded properly can you post again macka

Mate you should be able to work out you torque at any of the plot points on your dyno graph. Just use this formulae. KW x 9549 / rpm eg 200 x 9549 / 4000 rpm. I don't no what the formulae would be for HP readings. But you maybe able to use a converter from HP to KW to give you a rough idea if your dyno gragh is'nt in KW I'm mainly interested in the torque readings as I have been told that they should be higher than a normal xr6turbo because of the higher compression ratio, but the actual KW maybe lower because you cannot run tha boost as high macka

Have you got any picks of you IC and intake setup? would be good to see how you've done it. macka

Thanks for keeping us informed I'd say that you'd be pretty happy. It would be good to hear some feedback in your own words how different the car feels out on the road compared to when it was a N/A xr6. Interesting to see that the factory NA tune was happy with the turbo fitted and suppling enough fuel @ 6 psi. Just goes to show how rich they must be running from the factory. It will be interesting to see the results once you have it custom tuned with the Edit. Pls let us know torque readings as well as KW output. Once again well done macka

Look forward to seeing what you guy's come up with Keep us posted and some pics would be good macka

Your right on the money

No pal, I was running Nizpro IC at the time macka
