BLACK BEAST BUILD Slicktop R-Spec

Being tuned at UAS?


PS. You might find the 1000cc injectors will run out of fuel quickly at your power level on E85, i know a few cars that have run out of fuel at the mid 400rwkw mark on E85.

 

yes At UAS

quickly popped in today and they had done a cold run with no probs in fuel pressure and injectors around 65% (from memory)

the fuel pump doesn't like heat and will be a problem at the track on a warm day even with a cooler ...not worth the risk .
will be taking it home and put another 500- 1000km's on it before changing the pump and more tuning.

Decided to leave the dumps for now and leave it at 21psi base boost.Spent too much time and money getting them right plus it Can't hurt

So Took it for a quick spin - seriously revs like a bike !
was just wheel spinning..hard to keep it off rev limiter with the 4.10
Its ridiculous power
The quaife drifts well too.

my street kumhos after the dyno




my power steering cooler in

 

Good god what happened to those tyres?! Bet you wish you didn't use them on the dyno now, those things are melted good!

Great results, Rob. She'll be an absolute weapon on the track, depending on the driver of course

 

You hit the nail on the head Eric. I was talking to JP today and Rob last night. They have AN10 from the tank to the pump and 8AN from the pump to rail. and a 8AN return.

This is clearly NOT what Aeromotive recommend. JP thinks it cheaper to get a NON fuel cooled pump than redo the piping. The pump is cavitating due to lack of fuel flow. This removes the motor from the fuel and makes it run hotter. Therin lies the problem IMO.

Every critiscm of the pump I have read ended up being its application and NOT following the recommendations. I only found one post where a faulty pump causing low fuel pressure.

The 100micron filter could also be blocked with crud seeing its a new system. Might need a clean.

I have one of these pumps as well and need a resolution to this. BUT I have 10AN all the way through for my system.

 

Hasnt JP got any bellmouth dumps left ?

 

no
he said you will sell me yours

 

LOL he is such a kidder You cant have the Precious

 

I still can't see the problem whether you reduce to -8 at the rail or at the pump .
Further more if it had -10 and temps still reached over 40 degrees on a warm day ,whats to say it won't have the same problem? worth the risk?
Its too delicate of a pump for me. .and its f#@ken noisy ..can't hear my diff whine :rofl:

At this stage still going with FUELAB (its brushless) as I'm not going to redo my plumbing and still have the possibilty of problem not solved.
It is cheaper to replace for me.
. its virtually a direct drop in

You can't hide from heat at the track.

dont have 100micron before the pump
have 40 micron on pressure side .

I may put a filter in between main tank and surge at a later stage.

 

I ran my pump to check it when It arrived. It extremely noisey with no fluid through it. Not too bad at all when its well primed etc.

Maybe we are hearing the issue Rob, Not enough fluid in it??????????

Anyway, if its cheaper to change pumps, than redo pipes. I would change pumps as well.

 

its sucking -10 from a 4 litre surge.. you not going to empty a 4 litre surge with a power run .
same noise cold, hot its obviously supplying all the fuel I need when it doesn't get hot .

I can get the fuelab for under 500 which has built in controller which wires straight up to my ECU
and sell my pump and controller .

 

another update

the turbosmart reg looks to be playing up .

We set it at 4 bar . after taking it for another little drive and bringing it up to temp it drops down to 3 bar .

So need to do a process of elimination starting with switching to different reg first.

some info
My water temps reached a max of 85 degrees from all the dyno runs which is great .
oil temps went just over 110 degrees which is fine as I'm not running any coolers yet

Will set up the twin coolers after 1000km run in .
Reason being is its pointless with the frequent oil changes and I want to get it to operating temps on start up as quick as possible for now .(street use)

starting to look like a car again .

 

A Turbosmart reg playing up ? I'm about to use one of the bastards lol

 

Fuelab arrived

Fuelab 1500hp Speed controlled pump.
645 lph @45psi .. (10.7 lpm )
570 lph at 80psi!
these figures are underrated as independant tests show over 700 lph @45psi
plenty of fuel.

fuelab 529 electronic fuel regulator -8an
controls the pump speed directly as needed by monitoring return flow.
no need to run off ECU .

now to work out if the injectors are enough with E85 .
Not a fan of running high fuel pressures.

will finish the base tune on 98 with 1000cc for now

 

NOOB ALERT...

what unit of measurement is AN ?

 

army-navy man

 

700 lph @45psi

@ what voltage though?

 

13.5

 

army navy waaa ?

 

-AN means Army Navy

 

so how does army navy relate to -8 AN ? makes no sense lol

oh thanks wiki : http://en.wikipedia.org/wiki/AN_thread

so its 1 1/6" per a step. interesting...
