New: FSP Pulley Review with EC Tune 2.0 (Jerry/Brooke/Shardul)
Fixed Supercharger Pulley Review with EC Tune 2.0
Jerry (EC) – Brooke – Shardul
There have been various questions raised about the tune for the FSP:
I can answer all 5: YES!
I had the previous (EC) tune and pulley for the last week or so. Jerry told me he was working on a variation, so I decided to wait a couple more days to install (plus, my mechanic <Dennis> over at RNZ Conceptz) was swamped. Today, the stars aligned, and the pulley went on.
I performed the flash via Euro Flash V2 and started her up.
Initially, the car hunted around for idle, and there was some significant surging, but as I have a Dashdaq / Zeitronix, I could see the STFT were simply trying to level the mixture.
After idling for about 3 minutes, it smoothed out and began to idle perfectly. I took it out and drove it very gingerly just to make sure there was nothing major (like going full throttle into a picnic area or something).
For the first few minutes it seemed to surge a very little bit , but I think it was a combination of a whole new gas pedal (feel) and the tune just getting situated. I drove home. Now, everything seems good to go...
Now that I know its running smoothly, I can take it out and see what it really feels like. All surgi-ness is gone. Idle is smooth as ever (better than my old tune). STFT's are where they should be… and
The car has LOST any SANITY it still had. Period.
It is now an absolute BEAST.
I never liked the small hesitation on part throttle typical of the clutch system. Mini Vans would jump ahead of me off lights as my SC kicked in. Sure, I could punch it, but then it sounded like I was trying.
That’s no more.
Boost, acceleration, and raw power are THERE. It is VERY easy to break the tires lose just leaving a light. You must have a very light foot. You don’t need more. That is the biggest change from a drivers standpoint: Instant Throttle. INSTANT I can say it 4 more times, until you feel it, you never knew your car could feel like this.
This is day one, and I have put about 15 miles on the pulley and tune. I am running an 83MM upper with a 190 lower. This is quite aggressive. I will be logging and testing over the next few days to provide feedback to Jerry. My initial opinion is that the tune needs nothing! Remember one thing: The power is instant. If your wife or kids drive your car, you may want to start hiding the keys from them.
Also, start saving up for tires. You ‘re gonna need it!
This is ground breaking. I know it took them a little while to iron it out, but its there!
I will update this thread as I begin to collect data. IAT's look to be up about 7 degrees (Was at 18-21 now 25 - 28) That may be off a little since the car was idling for a while, and when I drove it, I was sorta on the boost a lot
And remember, I am running a 190mm on the bottom

There have been various questions raised about the tune for the FSP:
- Is the tune finalized?
- Does it work?
- Is it ready?
- Is it worth it?
- Does it make your car awesome?

I knew an updated tune was nearing completion and I was going to wait until I got Dane's impression... but I couldn't wait. I ordered an 80mm yesterday and it will be here on Wednesday. The both of us will be logging our similar-but-different cars to see what is up.
The excited tone in his text messages let me know that I needed to get this. One text said something along the lines of: "Best F**king mod I have ever done." The words "stupid" and "insane" were also used a lot, lol.
I got the 80 to go with my 175 crank pulley. Insanity level dialed down just ever so slightly from the wagon-wheel 190 on his car. My biggest concern is with IATs... wait, no it isn't, I have meth. But yeah, the cruising IATs I am curious about. Right now, I see typically 15-20 degrees over ambient, sometimes a few degrizzles higher.
I want that instant throttle response and I really can't wait to ditch the clutch and that rotating mass. I want to see if I can do second gear burnouts from idle

A 190 crank plus this 83mm very interesting. So what does that come to total relative to the crank pulley sizes? 200?
I run a 195 and have IATs under control well with the KC and meth, but adding a trunk tank just for even lower initial IATs and quicker recovery. I had the smaller upper clutch style I wanted to install but never did. I feel you with the lower end when the SC isn't engaged and you don't want to stomp on it.
Is there a FSP that is close to the stock sized upper so us bigger crank guys can enjoy the "benefits" of a FSP without really increasing boost and IATs?
EDIT:
So I looked on the other planet and saw Brooke post there is a stock sized pulley. What size would that be?

I , could be wrong but in the S/C pulley the S/C engages at around 2300-2400 rpm and in
this one it's always engaged, right ?
If yes, then wouldn't it affect MPG by huge amount even when cruising around town ?
Always engaged would take away the luxury effect of the car since every time you step on it, it'll go right away lol , it'll be like the car is always in the
right gear right rpm and what not.
Maybe my views on it will change after putting one on in the car and driving it for a while but my job keeps me on the travel most of the time
and I cruise most of the time.
Got some videos ?

It is engaged all the time. So boost comes on very fast. MPG.. hmm, not sure yet.
In terms of drivability, I like it better that stock, because the car has power as soon as you touch the pedal. Not 12 seconds later like the stock system (when just cruising).. Granted, you can get past that delay with your foot, but now you don't have too. It takes out the delay of the clutch.
I would bet a stock car with the 90MM pulley would be perfect for a normal person. I am not that guy. With my mods, the only think I can equate it to is a two-stroke motorcycle. <make two-cycle motorcycle sound now>
Denroll has one going on Wednesday. His set up is a little less aggressive, so lets see what he says. Mine is over the top. I may need to back it down a notch
PS- If you put this on, you will need to change your sig:
After the acceleration, my gf goes OMG, let me out of this ****ing car NOW!!!

The stock pulley and I have been fighting the last few days. I can't get that bloody ******* off! I tried impact with swivel and lots of psi and even tried massive breaker bar! Oh and i even broke 5 different wrench straps.

not be suitable for me. Even if I have to overtake someone, the rpms don't go over 2500 hence S/C doesn't
engage which in turns also gives me good gas mileage.
I already have S/C pulley which is 83mm I think, are you saying 90mm FSP is better than 83mm (clutch) ?
Since you got 83 mm what does it equate to in crank pulley size ? and there is a race pulley (as they call it)
It's 77mm , how come you didn't go with that , since it generates the most power ?
Sorry, for a lot of questions, it's just that you are the first one who has the updated tune with the pulley on .
and lol haha at your comment.

This place is a joke.
So you mean to say, the new fixed pulley and tune ONLY, on an otherwise 100% stock car, gave 473RWHP? Call me skeptical, however I see the "before" dyno looks right, at around 400RWHP. Hmm...very interesting. What is the 80mm fixed pulley equal to crank pulley wise?
