sweet dude!

 

on friday I took off work to install my supercharger. I have spent a lot of time getting everything together and researching everything to make sure I got it done right the first time. I came across a great deal on a used v3 supercharger that I couldn't pass up, the only thing was it was for a rev-up. I didn't see this as a big issue since I've messed with revups before and I knew they were not that different.

spent 22 hours installing everything solo, from the oil cooiler to modifying the bracket... and then routing all the piping it ended up being a slight pain in the ... not to mention it was my first time attempting to tune.

the first issue I had was that I mounted the intercooler too low. there ware two holes that conveniently worked so I thought that was where it was supposed to go after jacking with the pipes for a couple hours I realized something was wrong, that's when I realized there was a big hole and a small hole on the bracket for a reason, I then moved it up to the core support and everything fit a lot better.

the other issues were related to the fact that I had to make a revup kit fit on my non-rev.. wasn't a big deal, I notched out the bracket so it would fit over the cam cover and then removed the top left cam screw in the right cam cover so the pulley didn't hit it. no oil leaks yet, but I will probably try to find a flat top allen screw to put in there, and probably put a washer to move the pulley out a tad.

the tuning was a bit of an issue, I selected PMAS and changed the fuel multiplier for my injectors according to the equation new k = old k * (old injector value/new injector value) I went from like 23k to 11k... I also put in the injector values that I found for mine, they didn't match perfectly but I matched the 8v and the 14v values, I assumed the fuel pressure was 43.5 psi, really wish I put a gauge on it. I kept jacking around with the tune and finally got it to where it would start, run, and then idle. I was scared of FI so I dumped a lot of fuel in just so I could drive to the tuner.

right as I was ready for bed (after working 20 hours on this) I noticed one of my oil cooler lines had a leak in it... almost gave up at this point and assume I would not make the tune date, but I went ahead and knocked it out. it was just annoying cause I had just changed the oil and I didn't want to waste it.

so I ended up going to bed at 4:00 am, I just took my time but I had to drive around and get some parts during the day which ate up some time, also took plenty of breaks since it was 106 outside (I'm in texas)

the next morning I had a buddy escort me to the tuner, it was running a bit lean under light load 13s-14s which was ok and under moderate load it was 11s to 12s which I thought was decent. once I got it up to the tuner he had some problems. of course my tune was all jacked up so he just started fresh. thats when we realized we had a problem with something else. He thought the MAF was having issues and questioned if I really had a PMAS, I ended up taking out the vortech pipe to prove it and thats when I noticed all the dirt and dust lining the pipe and the MAF sensor. I can't believe I forgot to wash the pipes out that had just been powdercoated!! after this was settled, I tightened up all the t-bolt clamps and he was able to sort out the tune. he fixed the idling and running issues and got everything finished on the dyno.

The car is awesome now, I know what people are talking about when they mention the addiction to boost! It's very fun. I asked for a conservative tune since I am going to be tracking and in the texas heat I'd like to be as safe as I can. So the tuner set me up with a map that had pretty reserved timing values. ended up making 350hp and 283tq @ 6.5 psi, on a mustang dyno that I previously made 242/221 on. I assume that my psi was low because my engine was very free flowing, this is fine because I'm happy with the numbers for my 5AT I will push it harder when I build my block.

here is some pictures and videos

I will get more install pics up later.

really need a LSD now, this open diff is making it hard to keep the 295s I have planted...

 

So did you pick up the Rev-up vortech kit I was eying on craigslist from the dealer for $1200.....hmmmmmmmmm. Congrats on the work and I bet you are beat from the install and heat. Take it safe and make sure you have a nice and reliable tune that you can beat on all day long versus chasing numbers on a Dyno.

 

haha i bet you do need lsd pretty bad, i need to get a ride in this thing

 

I second what Faiz about the tune.

 

uhh you and faiz need to read I think

 

lol

 

Nice build and welcome to the FI family. Its very addicting and may eventually want more power. Its a very nice set up especially if tracking the car. I prefer a supercharger over turbos on a street car, they have a nice linear power curve. I've had a Vortech on my car since Dec'04 and one of the few who has not stepped up to TT.

 

lolz...I read that and glad you chose a safe tune over number chasing. Now try not to get the itch to upgrade the pulley or go back in for an aggressive tune once you crave mo powa. Enjoy the accomplishments and look forward to your next mods.

 

Vortechs are fun in a 5AT....seems like it pulls forever and drops less boost between shifts....congrats!

 

how do you like the 928 mod? and how much did that cost?

I was looking into that in the future.

 

It will allow about 2PSI gain, its more economical than upgrading to a T Trim. I did the swap myself and paid $500.00 for the impeller.

 

looks good rob

 

WOW awesome!

 

much respect
