Problems With Power After Turbo Install

[sam5709]

ok iv finished putting in the hiflow turbo, atm until i get the $ for engine management iv put the stock injectors back in and am still running the stock ecu

iv set the boost to 10psi but the car is making very little power

on the dyno before i put the hiflow on it made 225hp atw, now with the hiflow on it made 130hp atw at the most, the afr's are ok and boost stays at 10psi until red line,, there are no boost leaks and everything appears to be hooked up ok, just has half the power

im taking the car back on friday to get a full inspection to find out what the problem is but im just wondering if any one can give me some insight on what the problem may be

iv been told that the stock ecu might have gone into some limp mode but we have tried disconnecting the battery to reset it but its still the same, the guys im taking it to reckon its some sort of timing issue, the CAS hasnt been touched either so its not that lol

any help would be great

oh by the way the car is an r33 gtst series 2,

mods,

splitfire coils

slide hilow

split dump/front pipe into 3 inch straight through

hks pod - s/s intake pipe

hks adjustable wastegate actuator with turbosmart manual boost controller

FMIC

BOV

im just suprised the h/f item only made 225hp?

i got 255hp on a stocker

[sam5709]

no no the 225 was with the stock turbo, with the hiflow it made half as much power lol

10psi on the high-flow will be FLOWING alot more air than your standard turbo, even with both set to 10psi.

You might be hitting rich-retard but geeze it dropped alot !

I had my HKS turbo with an R32 actuator on 10psi with no boost controller, and i think it might have even been pinging when pushing it so just be carefull

10psi isn't 10psi if you know what i mean.

This might not even be the problem, but i thought i'd throw it out there

if it was going into rich and retard wouldnt it show while looking at the afr's on the dyno?

Yeah, huess it would, but depends if the dyno owner was looking for it.

If only a power run, they might not have cared.

And pulling the timing isn't something you can't really see.

[sam5709]

hmm yeh, i was standing next to the car keeping an eye on the boost gauge which was stuck on 10psi as he had a close eye on the afr screen he had, he said afr's were spot on

[r33cruiser]

have a look at the torque curve to spot rich and retard

u wouldnt happen to have a copy of the dyno sheet wud u?

[MBS206]

Rich and retard DOES NOT "richen" the fuel up.

It only retards ignition.

In fact, on my dyno graph with stock ecu, when I hit R&R my AFR leaned off slightly (Headed back to a nice 11.5:1)

Just rips timing back to around 6-8 degrees

[sam5709]

oh ok kool,

nuh i dont have a copy of the dyno run, was to embarrassed to have it printed out haha, although ill go back tomorow and get it printed

[sam5709]

car will be going in tomorow morning for a full check etc etc, so hopefully will find out what the problem is

been getting alot of comments saying its putting out so little power is because of my number plates LOL

[str00th]

I know you said there are no leaks. But to me it sounds like a leak you must be missing. When the car is on the dyno and the turbo is spooling you wont hear the leak. Wipe all the piping down with a soapy water and double check.

[sam5709]

ok there are def no boost leaks, the workshop i took the car to was under pressure to get cars out today and not much happened, we did eliminate things like boost leaks etc,

they have nailed it down to something wrong with the cas and the camshafts, as they were trying to adjust the timing via the crank angle sensor it was apparent that no timing would adjust, no matter what position the cas was in nothing would happen to the timing, unfortunately they ran out of time to go any further and they dont open back up until the 2nd of January so its a waiting game until then!!!!!

any one had anything like this happen before?

[sam5709]

just coming back to this quickly, could the cas be the problem, or the camshafts?

[sam5709]

ok they have pulled everything apart and from what they can see is that there is like an aluminum plate or something behind the cam gear cover that has cracked or something along those lines so the cas cant do it job properly,

while they were at it i told them to change the timing belt and they said that it has slipped two teeth

they are also doing a few other bits and pieces while they are there, oil pump water pump etc, so should have the car back next week

sam who do u go to for the tune etc?

[sam5709]

i take my car to tim slackos west racing in ozzy park
