Outer Limits 4x4 Board

This could be interesting , I purchased an E90 Supercharger Kit from an AULRO member not long ago and when it arrived I took down to DPL as they were going to check the kit to make sure it is complete as advertised.

Bruce has fitted many of these Kits to Rover V8's before.

so When I dropped it off , shortly afterwards I recieved a phone call,

1stly the Blower impeller blades have had their coating Flaked off ( but hopefully that won't pose a major issues in term of sustaining boost ) and

2ndly the COG pulleys are Flogged. so I'm up for a few more hundres $$ to get the Pulleys replaced :x and if I have to get the blower serviced may be more. I contacted the seller immidiately and advised him of the situation but his reply was he was not aware there was any problems with the supercharger kit ??? but that could be argued...

Fair enough ... I try and give people the befinit of the doubt....

Bit of background on the Engine, it has standard CAM , Lots of headwork mainly ports , new valve springs , intake manifold inlet ports etc , Low comp motor , standard CHIPP with 14CUX and standard injectors , think i'm only planning on running as much as may be 9 psi without intercooling , just so mainly to increase VE efficiency , but any increase in Torque and power is a Bonus :armsup: \

So I will update this post once it's all done and may even take to Graeme coopers for a 4wd Dyno and post up results.

Here is a Picture of the E90 :lol:

Here is the Old girl @ stockton :lol:

Being a 3.9 i would for shore be doing the cam lifters and timing chain' they are known to wear very badly. Seems odd that if it has had head work done in the past that they were not done at the same time.

Hi Nottie

The Motor has Had new Cam and Lifters fitted by previous owner , I'm not sure about chain ,That work I can do at a later stage , it's mainly a get around town vehicle , when I pulled the heads off to investigate a Pressurising cooling system issue I found an almost blown gasket , but before I fitted the new gasket , I took the head to a servicer and had a lot of work done on them as mentioned earlier . The V8 has Torque to Burn

dunno, we have a supercharged 3.9, and i wouldnt be righting home about it. I got smoked by a bog stock 4.5 hundy off the line...

The rangie drives pretty nice as it is without the blower bolted on , I just want more driveability with the supercharger bolted on , but I don't intend on Dragging everyone of the set of light with it thou.


Edit : I Wasn't righting home about antything , just merely saying that it is nice to drive and should be even more sweeter with S/C on .

will be interesting to see pre and post power & torque figures.

sam , I'll try and do a pre and post results and post them up on here , the only 4wd dyno I know off is graeme cooper but he is a bit out of the way to get to

Damn !!! A before and after dyno runs would have been good to see

This is the V8 motor , I cleaned it up quite a lot of the parts by hand

and while I had heads off for service , I sent the extractors away for

ceramic coating and replaced the engine mounts . I'll try and get

before and after dyno results.

bastard!
Need more powaaa!!!

hahaha

have you decided which engine you're going transplant into Fluffy ???

Still havnt herd back from engineer re 6L.
But so far to date, still contemplating the LS2 to 4L80 and mating it to the LT230, or possibly going to an atlas case. But the figures I have so far are not very promising.

The only other dillema is the length of the 4L80 along with the marks adaptor.

Back on topic, very keen to see the power figures of your stock engine.
A graph of the power delivery would be nice too.

Anthony , I'll try and book it in to GC for a 4wd dyno , I'm personally quite curious to see Torque HP figures of the V8 motor prior to bolting up Supercharger and then doing a dyno test afterwards , a comparrison test could be good.

It will have to be run on a dyno to tune it regardless, so just find out what dyno Bruce Davis will be useing and run it up their prior to fitment

Lots of Q's what sort of ECU? stand alone? piggy back? is it on LPG?

The fitting itself should be very easy.......you could of done it yourself Khos , just getting the tuneing right is the issue

Upcoming issues will likely be, the fuel pump won't cut it, the injectors will be fully cycled, but that will most likely require an adjustable fuel reg, make sure the ignition system, plugs leads etc are in good knick

Thanks Matt,

I don't know what ECU he's going to be using ? wheather it's a stand alone ECU or piggy back system ? not sure , The car runs LPG and there is already a piggy back system hooked up to the side of the dizzy with one of the original wiring looms plugged into. I'd say this adjusts the ignition timing for LPG.


Re: fitting , I know the fitting the blowr is easy but once I've fitted the blower I'd still have to drive it to his work shop to set up the fuel , ignition timing and the rest of it properly , I didn't really wana risk driving it , so I leave that to the experts , should have got you to fit it all for me and set it up


I recall him saying that he will have to install a different fuel regulator as you said , all the leads , ignitions plugs , dizzy are in good nick, he checked that out last time the car went it to diagnose the rough idling issue post fitament of the heads , he serviced the dizzy and fitted an OE rotor button.

I will have to find out which dyno he uses and get the car to them prior.

hehe, not having a go, the torque will impress you, and its a smooth option to take. And it will make the overtaking option a whole lot easier.

What annoyed me, is that the car should of been a whole lot quicker than it was, considering i drive a modified turbo TB42 with a lot of grunt. And i defently should not of been so negative in regards to the car.

However, and furthermore, i really should add (after I was told about the car later on after my initial post), that the car was running a std computer with the S/C, (which it is capable of doing) However, once we finally get the computer back (Justin C.....!!!!) hehehe, it will be very interesting to see how it goes. Apparently since Eric fixed the thermostat, the car is running very well, and a lot better, so maybe consider looking at yours.

Eric's runs a chipped std computer via Bruce, but to be honest, I'd seriously look at the aftermarket options if you think of going back to petrol, because in the end, if you want to take the motor further, and seek more power/performance, the aftermarket comp will allow for it.
For example, I've seen a lot of turbo RB30 projects start out with a piggy back computer, but the owners always seam to end up having to spend the money on an aftermarket computer, however, how this relates to a supercharged motor, i can not comment.
Eric's has an interesting set up regarding the fuel, and how its delivered, and i have looked at it once or twice, and it still makes me go ummm... but it seams to work...
However, gas will be different.

Good luck with the project, it will come along nicely.

After playing around with my piggy back (haltech) ecu, I would have no worries about running a SC from it.

Got to test out one of my maps (started numbering them, testmap5 ) offroad for the first time yesterday, and also did a short highway trip and it is great.
No loss of power in the mid range and holds rpm a lot better. Only downside was its lost a bit of pedal response at highway speeds, but a touch more fuel and slightly more advance in that area should bring it back to sweet orsumness!

The improvement I have got out of my previous tune alone is remarkable, and cosidering I am just a noob at this, I would love to see what a professional tuner with a bit of pasion for what he is doin could come up with.

So I guess what I am saying is a piggy back chip should handle the SC fine!

p.s. as mentioned I am just a noob at this but I know the 14CUX is out there running standard on 5L v8 and upto 500hp machines. It does a damn good job on some of these motors and it deserves a bit more credit IMHO. The air flow meter on the other hand could be improved

You can always step up to the Gems 4.6 air flow meter.

This will be considered at a later stage and definately if a supercharger is brought into the equation.

Back on topic - Disco_owner, any more news re dyno at Greame Coopers?

I saw Bruce again at the landrover Expo on sunday , he would like for me to drop the Rangie off at anytime during the week but said he needs it for a week and he emphasised a week.

Also he did mention he doesn't ues a Dyno to tune the Rover V8 with Supercharger Bolted up and running( he doesnot have a dyno ) however he has provided me the details of a local guy with a 4wd dyno and is happy for me to take the Rangie to Him and have it run on Dyno and get the results Prior to the S/C being installed and engine Tuned and a Remap. and then back to him for a Post Dyno.

So at this stage the Rangie is still work in progress , but I'm going to post up results in here.

haha , It's all Good mate . Should be a good project , I 've heard similar things about Piggy back systems and owners not being entirely happy with the state of the tune, if I had the dollars I'd definitely be going the after market ECU not a piggy back system , something like an EMS

http://www.autotechengineering.com.au/E ... ng/EMS.htm

no

Grimace runs a piggy back and it is coming into its own now that he has a handle on tuning it. Haltech Intercepter i think

Khos,

You will run into maximum duty cycle problems with your injectors with a supercharger unless you fit a tornado chip or similar that lifts the maximum duty cycle. The 14CUX sets the max duty cycle at something like 75% which is not enough at high revs. I think Bruce Davis has access to either his own or I suspect UK chips for this. Be aware as these things are not cheap.

The Brisbane company Syntek now does a MAP sensor replacement module to replace the MAF in a 14CUX so this may be an angle to look at also.

Regards Philip A

Philip ,

so if i understand it correctly , what you're saying is if the 14-CUX MAF sensor is replaced with an after market one such as the syntek MAP and 14-Cux ECU is re-chipped with the Tornado EEPROM upgrade that the Duty Cycle will be lifted to 100% duty cycle ?

Thanx for that i have been trying to find something like this for a while. The self learning programmable one looks like a good thing.
