I made the mistake of buying a 83mm pulley without thinking too much about it, my 90mm is on it's way out and needs a new bearing so I thought I should just get a bit more power while I'm at it.

Now I'm not so sure if my car is even ready for such a thing...

What should I look out for with my stock injectors as a tell tale sign that they need to be upgraded for 550c? Am I to log something? Don't have a wideband so probably nothing...

Will my crankshaft be in jeopardy? I saw some thread about pinning the shaft and with my big pulley it got me worried.... I really wish the car just came with a stock crank when I bought it.

I don't have meth if that's what you're hinting at. I don't track the car but I do live in a hotter state...

I have a PLM cooler and a 010 pump currently.

MACEDON

If I do upgrade injectors what is the best kit to buy that will be plug and play?

Looking for reliability and ease of install

you can go with 550s or 630s i have a new set of 630s for sale with the pigtails .... they both are easy to tune for just have to tell jerry or tony what size u have an they can send u a modified tune. I bought this set bout 2 monthes ago an couldnt find em so i bought a new set 2 weeks ago installed em an then while cleaning the garage found my other set lmao. So ill give ya a good deal if interested. I love mine they work great.

MACEDON

Where'd you get em from? Brand new right?

E55amg0220

brand new never installed .... i got them off ebay their the same ones vrp sells. They are bosch ... if u want i can install em an make sure they work perfect its pretty easy. Ill give ya a warranty on them they are perfect theres pics on my thread in this forum

You will need to upgrade your cooling to run the 180-83.

Id say Superflo, Secondary HE, and a bay or Trunk tank (trunk is best) would make it ok for you.

MACEDON

Is the superflo pump a plug and play kit or will there be tinkering with the wiring?

VictoryRoadPerformance

It is a 2 wire pump, you will need to cut and splice into the factory wires

^what about all this?

I'm not opposed to getting the pump at all I'm just not too good with electronics, I'd hate to end up frying something 7-8 months down the line. I daily the car and take it on road trips.

VictoryRoadPerformance

We do not sell 4 wire configurations anymore. 2 wire only.

MACEDON

And because of that I don't need to reinforce anything or what

VictoryRoadPerformance

right. The pump runs great on factory wiring, some customers prefer to run a dedicated wire from the fuze box so its always running under switched power.

You can have your tuner command the IC to be on all the time via ECU calibration.

Do you at least have long tube headers? If not, don't stack pulleys. You'll just be adding more heat with no benefit. Depending on elevation you might even go over 17psi and hit limp mode but that's if your sea level and your DA is less then 500ish. My DA is always around 2800-3300 in Vegas and when I go on trips to SoCal I gain about 2-4 psi due to being closer to sea level. One time I was at PCH right by the beach I went from seeing 12-13psi in Vegas to 17psi at Newport beach. That was when I was 77/168 stack similar supercharger spin rate of a 180/83 but with mid length headers. I bought long tubes immediately after this incident.
Even with just mid length headers I wouldn't go anything over a 185 crank or equivalent.
I would replace the bearing of the stock supercharger pulley for now if i was in your shoes.

MACEDON

I have mids. The pulley was sold to me by what should be a very experienced vendor who should know this type of stuff... and he's located in a very low lying state just like me.

I'm in FL, so what you said kinda scares me. I'm not really planning on getting bigger headers honestly, so maybe I should just put the pulley up for sale and chalk it up to a nice $50-60 lesson.

good call -- it may save you money and aggravation in the long run

Back when I was I was stacked I was 77/168, mid length headers, 82mm tb , 2 heat exchangers, 10 gallon trunk tank, 550cc injectors with looped fuel rail. You need meth to cool
it down from climbing too high. The car would just gets too hot especially in the summer. The ecu pulls timing at 3 tiers:
95F - 3.5 degrees
113F- 6.3 degrees
149F - 9.5 degrees

My cooling still wasn't enough in 75F weather. My temp would start at 56F with ice and get to 129F on a 3rd gear pull at the dyno. I would recommend adding a meth kit to stop the temps from climbing so high. I added a 10 nozzle post inter cooler and a 3 nozzle on top of the snout. My temp wouldn't climb higher then 95F via zeitronix ndash on a 3rd gear pull at the dyno.

If you’re on recall fuel pumps I wouldn’t do it either. I lost a compression on cylinder #8 within 6 month of using a 77/168. I would upgrade the fuel pumps and drill some holes on the sides and bottom of the fuel buckets. To help refill the bucket so the pumps are always have fuel to pump. The new recall fuel pumps don’t have a siphon jet in the bottom of the fuel buckets like the original buckets that first came with the car causing a fuel pressure drop and going lean.
This issue doesn’t allow the fuel buckets to refill the buckets with fuel fast enough which causes the fuel pumps to not pump any fuel during a pull. If the pumps aren’t pumping any fuel they'll over heat and cause the fuel hat to get burnt. Which is what happened to me and unfortunately costed me a motor

Jesus.

What I'm getting from this is that even my crank is too much. Definitely not interested in installing a meth kit that seems like such a pain in the ***.

It came with the car I didn't really even know when I bought it... I want to downgrade to a stock crank to be honest...

I actually want to go down a notch... I have trouble keeping the heat off. I'm constantly running 22-30F over ambient.

Maybe I need to bleed my cooler again I don't know... I think getting that superflo pump might be the best money I'll spend, tough **** because I like JUST renewed my pump just a few weeks ago.

Das_it16

I would try the secondary heat exchanger first. It should lower temps pretty well. This is the one I used and its easy to install.
