Jaydece's Major Development Project

back from barwon heads and gave the car some good squirts on the fwy....all good so far but I must admit I'm paranoid as F%$# that it's going to die on me......

here are the results from springy motors tough dyno....

the hose that came off that stuffed up my result...

[Devour]

Car looked great yesterday Justin, was good to see you and your car.

The dyno run for me was impressive to watch, its a pity it didnt turn out the way you planned.

Hopefully your car gets all better and is back to putting down some real power again like the first time i saw it!

[Gambit]

Agree your car looks great in the flesh! Very nice power under that curve too btw, hope it all gets sorted too.

Hello All,

I've been on the research and investigation run into my car's pinging issues.....and have found the following:

After springy motors dyno day I noticed whilst re installing back the perrin intercooler that the turbo housing flange hole that the fabricator(HP/F) made is bigger in diameter compared to the intercooler side...from the top of my head it's about 5-7mm diameter difference........WTF! ( emailed HP/F about the problem with little returned response ) .....

1/ I couldn't use a flange gasket as it doesn't line up properly on either side ( ended up using silicon and paper gasket )
2/ With the outer diameter bigger on the turbo side there is a restriction as it enters through the intercooler side ( as air rushes through it basically hits a wall )
3/ At this point in time I want to break and throw something against the wall farken!....I'm no mechanic but what are the chances this is affecting flow? efficiency? pinging? etc....

At this stage I could modify the perrin intercooler and open her up......but I'm not going to as I believe this intercooler is best left alone and should go to a new home......

Now your all probably thinking * his going FMIC isnt he?....* ahahahahaha FARK! YES........and YES....I know I said I wouldn't but I am now......and I realize that I've modified the GTX turbo inlet for nothing now! ( i can hear phat gt saying, I told you so...you had to take the hard way....farkhead )

Hi Justin.....remember there is a hard way and an easy way of doing what your planning on doing and i can see your planning on doing it the hard way the hard way is offen whats seen as the easest way and more offen than not ends up being the hardest and the most costly way. what i have learnt over many years the easy way of doing things alway looks like the hardest way but this is not alway seen to be the easest way for most people in the car modifying industrie ,hence way most peoples bill are so high ......... i hope that makes some sort of sence

* sigh*

So this is what I've got lined up: http://www.garage7.com.au/home/index.php?page=shop.product_details&category_id=92&product_id=1440=0&option=com_virtuemart&=53

I've just purchased a HDI GT2 FMIC intercooler kit for $570.00 shipped via hong kong ( AUD $ is very strong, couldn't say no to it ) should arrive in the next 5-10 days hopefully...

With the help of scott I will be modifying the intercooler kit to:

1/ avoid losing foglights and front crush bar
2/ custom adapter flange pipe to suite the farked up turbo inlet
3/ retune of course.......considering my options on this
4/ attaching digital temp sensor unit
5/ cusco water cooling spray kit and cusco controller ( hmmm.....we will see )
6/ coating / painting intercooler kit black for stealth look

I think that covers most of my plans.......looking quite forward to doing this let's hope I can back it up with some good end results

Cheers Guys!

To be quite honest that is extremely lazy and down right negligent of the installer to just fit it like that.

I would of just port matched the intercooler inlet and bell mouthed it to suit. Would of taken 30 mins and made a big improvement to flow.

FMIC is the way though for bigger numbers.

[Gambit]

Good move, pain in the arse when shit like that happens, take it to springy now

Best of luck with it all.

Does anything have to be cut installing an FMIC like that? And would it fit with the stock airbox still in.

good questions Kieran....on the HDI manual it does state having to convert or use a CAI, but since I'm modifying it to suite my application I dont see why you couldn't retain your stock air box, I have seen people do this with other kits...and with the intercooler itself....I will need to trim the bumper at the bottom slightly...

But since scott has his fabrication setup he told me we can always chop the end pipes off and modify to fit and or cut it to shorten the height, thats how he did it on this stagea, shortened it/reduced the height and re welded it back together...

here's a perfect example of a car that has a FMIC with stock air box......GAMBITS! ahahahahahaha taken from legacy.com

That is very poor form from the fabricator, very 'backyard' mechanic style. I'm fairly sure it wouldn't affect pinging, but is not doing any wonders at all for flow. A nice little pressure spike and plenty of turbulent air around where it necks down.

In terms of looking for a new workshop, there are plenty of recommendations in the tuning section that are worth looking at. I've had a good experience with Paul down at Chasers in West Melbourne ( http://chasers.com.au/tuning/ ) and have no hesitations at all recommending him. I think they also do some fabrication work down there if you need it? (don't hold me to that one though)

Best of luck with everything mate, I think you're overdue for some!

[Kekotic]

Thanks Justin, good luck with the install

Thanks for the support, kind words and advice.....really appreciate it! ah...the joys of modify a car....

Hey mate - fantastic setup you have there.

I had a similar problem with my car running rough on the weekend due to the same vacuum hose although mine wasnt disconnected it was split. Only discovered it after pulling off entire inlet pretty much.

Thats shocking regarding the turbo outlet flange - as said a few more minutes with a die grinder or dremel bit wouldve fixed that.

Good luck with the rest of the setup mate, but dont be disheartened when things go wrong (and things will generally go wrong)- remember these cars were never made to be pushing 250kw atw so inadvertently you will get some gremlins here and there.

In terms of E85 - i'll throw my 2cents in.

I have a drag car 4 cylinder turbo that was making 437hp at the wheels running 28psi on BP98 and a bottle of octane booster (drag car so could do this).

Switched to C16 race fuel with no other changes and made 492 at the rears on 33psi

When E85 became available (outlet a few blocks from my house now !) I changed injectors, added a second 044 and made 486 at the same 33psi. To give you an idea, E85 is $1.00 a litre, and C16 is $180 for a 20L drum ($9 a litre) - for the price, the e85 made only a little less hp than the race fuel.

Availability is the biggest issue, but if as coyote has suggested you can run dual maps, then this is the way to go. Might even look to converting my daily GT to E85 given the proximity of the outlet.

Although one more thing people neglect to mention with ethanol fuels is this: Yes they are more 'green' - but people are forgetting that plants and crops are required to make this fuel. "So What?" I can hear people say - well if all these resources are being dedicated to making bio-fuel, think of how many more people across the globe are going to starve as food shortages increase. Also think about the surge in supply which will only push food prices further as farmers who used to supply their crop for human food consumption are being lured by the oil companies' $ signs to dedicate their acerages to fuel supply.

food for thought (no pun intended)

[jaydece]

dr20t AKA Mick.....Wow what a post.....thanks mate....and your statement on E85 and resources.....very powerful food for thought! if only E85 could come from rubbish, nappies, rotten fruit......give it time.....hopefully politics and corporate greed wont stop it in the end........not to mention us human beings in general.....

Cheers!

[rooby]

... if only E85 could come from rubbish, nappies, rotten fruit......give it time...

Then we could go back to the future too

[Nalnoc]

The yanks make their ethanol based fuel from corn kernels, a pretty big food crop over there, but are currently trying to find a way to break down the husks to make it instead (saw this in a doco a few years back, don't know how successful they were).

Over here (please correct me if I'm wrong) we get our's mainly from sugar cane and wheat by-products, not the food stuff's themselves. So we can feel much less guility when filling up with E85
