just got my set up done today!!!

 

wow sweetness. lets see some videos now!

 

Good job on the engine bay setup! Looks really nice and clean!



Spec.

 

u guys think a FPR is mandatory with a turbo like this?

 

yes, you will be almost doubling your stock fuel consumption (without it, it can drop to low and lean out the engine.). and upgraded fuel pump of course.

 

yeah for sure. u need to start with a higher base pressure (42psi) then have the rising rate go from there in order to give you the pressure you need at boost.

 

An FPR is like a wastegate. If it is undersized, there will be pressure spikes, not necessarily a drop in pressure. Pressure drops are caused by leaks, insufficient fuel flow from the pump, etc. And the typical Aeromotive unit that people run is a 1:1 unit, not a rising rate unit. An adjustable FPR lets you set a different base fuel pressure which helps atomization for larger injectors... but in theory the stock FPR should not automatically make you go lean and blow up if everything else in your system is working right.

I think you could get away with it depending on your injector setup. It might cause some tuning problems if you get a pressure spike up top though. Remember though that there are FD's making a lot of power on the stock FPR, which I can't see being that much different from an FC's. Stock FD has 550/850, and there are people running 850/1300 on the stock lines and rails, which is enough injector for 400rwhp.

Now, does that mean keeping the stock FPR is a good idea? No. But I disagree that it will a priori blow your motor or automatically cause a lean condition.

 

i have done a few setups that are currently over 400rwhp using the stock FPR...

i'm suprised so many of you aren't using a GT35r.. the 60-1 and 62-1 are good turbos tho. just not a fan of turbonetics, which seems to be the main supplier for these haha.

anyone tried the Master Power 62-1?

 

Rising rate regulators SUCK.

 

the aeromotive with the vacuum nipple on it is a rising rate.

 

it's all in how you look at it.

1:1 technically keeps the pressure equal while boost is pushing against the injectors.

RRFPR's (10:1, 12:1, 16:1) force the injectors to push even more fuel per the normal injection time the ecu is opening them for.

so a true rrfpr is NOT what you want.

 

run something like this?

Almost all aftermarket EFI FPR's are a 1:1 rising rate. As Zack already stated, the pressure is risen one psi in the rail per lb increase in the intake manifold to counteract that manifold pressure. This is the norm and it also comprises stock FPR's on turbocharged cars. While stock FPR's are not adjustable, aftermarket ones tend to have an adjustment nut/screw so static rail pressure can be risen or dropped.

There are some aftermarket FPR's that have an adjustment for increasing the fuel pressure/manifold pressure ratio. Zack mentioned these too. On some of 'em you can go as high as 12:1. I personally think they're a bad idea. Sounds great on paper, but it doesn't make up for a good standalone EFI system not to mention the potential for reducing pump life.

Hope this helps,

Here's my setup.

GT35 plain bearing.



I used to run a t04-s, and then a t04-r (still have the R in my garage) but among other reasons switched over to the GT series.

Haven't had it wound out too much yet, but transient response is much better with the GT turbo then the older T series thats for sure. To be fair though I can't compare the R to this turbo since the R was running a 1.00a/r and this is a .84........but the T04-S was a dog in comparison to this turbo.

 

hey guys I turned up the boost on my 60-1 T04S, got some boost leaks fixed etc, and now it is pulling very hard at 19psi (this is on race gas, I have a large supply of it). I am waiting for my MSD 6AL box to get here because I am getting ignition breakup and hesitations.

The spool isn't so bad even with my HKS log manifold. I think I'm getting 19psi by like 5000 rpm? and that's with a ghetto home depot boost controller, i'm sure it will be better when I can afford an AVC-R. Right now the powerband is a lot like my old 88 GTU which made 172rwhp and a had a very linear powerband with not much low end and a strong top end. Except with the T04S at 19psi it is probably making high 300's at the absolute minimum provided that everything is working right.

Interestingly enough, I haven't been having any major wheelspin problems despite my 225 Sumitomo HTRZ-II tires. I don't know if that's because my car is in fact slower than I think it is or what. Maybe it's the lack of low end torque that keeps it from spinning. It breaks a loose a little bit at the very top of 1st but that's it.

Also take note that you can get a ball bearing 60-1. atpturbo.com sells it I believe.

 

thanx for the update. takes some video and post on youtube

 

Good work

5K for 19psi sounds a bit hit high for a .96 A/R hotside. Wonder if the log style? Still I dont think it will phase you

If you running race fuel Id be expecting you to get close to 400 rwhp.

I dont know those tires, but I know guys running close to 500 rwhp and cant break good 225 rear wheels. Its going to depend on the quality of the rubber your running.

Also I still run a crappy T peice boost controller. Not great but not bad.

Are you still holding full 19psi at 8000 rpm ? or is your ignition brake up to bad ?

read the ignition breakup threads in the haltech section. im experiencing cut out but i think claudio helped me try some things... you might want to take a look.

 

I installed an MSD 6AL box on the leading ignition coil the other day. That combined with the B10EIX plugs gapped at .028 appears to have eliminated the hesitations mostly. I haven't driven it too much, but I got a chance to drop the hammer in 1st and 2nd and some of 3rd. 1st gear is nasty and spins somewhat, but at least it doesn't wheelhop. 2nd pulls hard, but 3rd is where it really comes alive... I got on it and let off at maybe 5500rpm just as the car felt like it was REALLY waking up--and I was going 80mph in a 45 .

I read some threads in the Haltech forums about ignition breakup. Some recommended an MSD box (which seems to be helping a lot) and others mentioned reshielding CAS wires, which doesn't seem to apply here because I am using a plug and play Power FC.

As far as boost control goes, well I think the boost creeping nature of the HKS log mani+ 40mm HKS wastegate isn't helping me. After datalogging my boost curve it appears to be nearly peaking at 15psi around 5k (this is in 2nd on the street, 3rd or 4th probably build it faster) and then slowly creeps to 19. I can hear the wastegate cracking around 12-13psi. I'm sure an EBC will help but the problem is ultimately in the wastegate + manifold combination. The runner on the HKS log manifold is only 40mm... I could do some custom plumbing to put a bigger than 40mm wastegate in, but I'm not sure how much it would really help compared to how expensive big wastegates can be.

The car is damn fast and I didn't really break the bank to do it (hence the cheap cast manifold), so I'm going to be satisfied for a while anyway.

Now, on to the pics.















And yes, I know the fan shroud and air filter are a little ghetto. I had to do it to keep the stock clutch fan. I am considering running an electric fan and switching it off the Power FC, but right now the stock clutch fan is cooling really well and isn't drawing a bunch of amps like an electric fan does.

 

Looks great ray. Looking forward to riding in it in a couple of weeks....

 

here is my setup:
fresh medium pineappleracing streetport
turbnetics 62-1
3 inch piping rto 3 inch FMIC (custom)
750/ 1680
E6K
4 inch himni DP
log mani 46MM tial wastegate
AEM tru boost boost controller
pineapple dual EGT gauge
etc.
etc.
whole build up is the pic in my sig. (its a link)


the wire mess WILL be cleaned up before its on the road......its not AS bad now.

for 20 minutes of run time on 2 different primary injectors....1 750 and 1 850!!!!!!!
thats being fixed as i type........
and yes, another crappy youtube vid...
hahahahha

 

^ what size intercooler piping is that? my Greddy 3 row (modified to fit) is 2 1/4" on the side going to the turbo, and 2 3/4" (60mm technically) on the side going to the engine, and that looks bigger to me.

 

great looking stuff here guys.
i just picked up a aermotive fpr and some SS lines. should be getting a turbo heat blanket soon. had to use a header flange as a spacer.
just got my injectors back from getting flowed and cleaned. just finshed making the oil drain line in SS as well.

 

^ what turbo manifold is that? I'm thinking my next turbo manifold may be an FD mani with a spacer.

 

mine is 3 inch.
