No I understand what ur sayin about that, but theres only soo many reasons ait temp will climb that high in a pull. Either an oil clogged fmic from blow by. Maybe the fins r busted....?? Maybe its a **** fmic...good name dont mean that part was a Friday or Monday built part. Just tryin to help, but a 50 f swing in a pull is out of the ordinary... Good luck.

 

I am still having an issue believe that an AMS Street intercooler, the one that uses a Garret core, is bad unless of course it is physically damaged or clogged. The thing is rated at 650WHP+

 

Good information David Thank you.

Shame you don't make an bf272 for the Mivec

 

I wasn't looking for help. haha I've been at this awhile. The FMIC is too small, I know what the issue is, I've seen it a hundred times on this core.

 

Hi Dave,

I've been fighting some issues with the black on my setup too. Similar thing happening to mine with power falling off early and it's not revving how it should for a LR2.0L

Lots of theories from the forum users (as per usual) - everyone with a keyboard has an opinion it seems.

Ideally I would prefer to get some sensors hooked up to the MoTec to try and get a better handle on exactly what is going on.

Fuel pressure on rail
EMAP on the manifold
Pressure and EGT on the turbo elbow
Pressure pre and post intercooler
Shaft speed sensor on turbo
Pressure on the turbo intake maybe...

Trouble is I'm short of inputs on the M800...
So I either need to throw some cash at it to expand the inputs so I can see exactly what the hell is going on. Bloody evos!

Speaking to Robert@FP I'm going to try swapping out my turbo elbow first for a fabricated screamer elbow. I need to up my fuel base pressure too as the injectors duty looks high too.

Interested to see how you resolve the issues on this setup. Easy fix if it's just a the core. Best of luck!

 

Kins, not sure how that dyno reads or any other details but the power level is good for a Black. I need more details of the set up, like cams, FMIC, intake manifold, exhaust, timing map, boost levels etc. to come up with any idea why it falls off up top.

 

Hi Dave,

This graph is a calculated atf graph. Blue lines are VP Import, Red is UK Shell Vpower.
From what I've seen Dynodynamics dynos over here seem to read similar to what I would expect on your guys Dynojet atw figs.
Cams are Jun 272's
Intercooler is a Pace core
Intake manifold is a worked stock intake by Tim Radley, Race Developments
Exhaust is a magnex modular downpipe, custom silenced decat, kakimoto cat back
Boost is 2.2 bar
Timing map - would have to send you a motec log file

Sorry for detouring off topic - please feel free to reply on my build thread rather than me add clutter to your thread.

PS - What's your plan with the issues your having with this setup? Ditch the original AMS core and swap it out for a Buschur race core?

 

Problem solved!

Just got the car back on the dyno. Instantly gained power, didn't touch anything. I actually backed it down a little bit from the first pull. First pull the car put down 561 whp/560 ft lbs in 4th gear.

Below is the dyno sheet comparison. I did a total of only 3 pulls today as the car was dialed in already.

For reference, the car had the poor fitment 3" downpipe that was on it removed and replaced with ours. We also removed the 3" crap muffler that was on the car and installed a small diameter Magnaflow where the cat goes and another in the rear. Matt needs the car to be quiet and it is very quiet, maybe quieter than before. We removed the intercooler and replaced it with our Race FMIC and our lower i/c pipe. The AIT's before were out of hand. Starting at 68 degrees were climbing to 122 in 4th gear. Today in 4th gear the car started at 77 degrees and climbed to 96 degrees. That's nearly 1/3 less temp climb in a single gear pull.

The peak gains are impressive enough but look at the gains at 8,000 rpm!

Before the changes the HP/Torque at 8,000 rpm was 503/334
After the changes the HP/Torque at 8,000 rpm is 546/364

That's a gain of 43 whp and 30 ft lbs of torque!

Here's the dyno sheet:

 

Nice results for sure, is this with the same Kelfords or did you swap cams as well?

 

OK.....more calculated numbers. I don't know anything about the Pace Core. I also don't know anything about the exhaust but I'd bet money it's not optimal. Hard to give advise on the set up.

The plan on this car has already been carried out, exhaust and FMIC fixed and it picked up big power. Dyno sheet is posted.

 

I didn't swap cams, it would make more power on our cams.

 

That is interesting and the reason why I posted my dyno results regarding IAT increase. This was also on my 4th and final dyno run and I measure IAT just before the throttle body.

 

Understandable mate.
I've no idea why everyone insists on using calculated ATF figs here in the UK. I think it stems from the history of marketing figures in the country. All new cars are quoted to hp atf so I guess it's a baseline to compare against.

The Pace core should be fine for my level of tune - it's the same core as what Ross Sport use on his drag car (although he has 3'' inlet and outlets) and quite a few evo owners use the core with good results.

I will have a closer look at the exhaust. Robert was explaining to me that the Black is sensitive to back pressure at the turbine. Ideally I would like to hook some pressure sensor to the turbo elbow, downpipe and a emap to see what's going on.

Good to see a new core and exhaust lead to big gains for you!

 

I don't know the entire set up on your car, turbo, sensor used, logging used etc. This car is running 8-9 more psi than your car on a 2.3 liter.

With a larger turbo, like an HTA86 the temps drop drastically, on a 2 liter they drop again.

 

Good info Dave.
So your race core is RACE fmic that is 3.8" wide, if he had gone with your largest BFIC core 4.5" would there be any drawbacks as far as spool or would it be even more efficient?
Just seeing if its worth going up to a 4"+ size intercooler.
