Alright...I already own the 3.4 pulley and belt. Obviously before I would even consider going to the 3.4 pulley I will need to upgrade my fuel delivery system...the upgrade I would do is the gt500 pump setup.....I will buy the $40 water pump pulley upgrade for tighter belt wrap etc....here is the questions though? For what would roughly be $650+ gt500 pumps, $40 for water pump pulley and who knows what for the labor to install lets say $300, is the investment worth it? yes I get a better fuel delivery system, but lets round it up to an even $900 to $1000, ? what can I expect to gain, 20-25rwhp and maybe 10 lb torque over my current numbers?...for that investment,,,do you think its worth it...I know if I was at stock numbers I would be like 20-25 rwhp...hell yeah...but once you break that 400rwhp barrier....is 20-25 even noticiable? LOL..... anyways....just thinking out loud here....any opinions and or advice is appreciated...now I know someone could reverse this on me and do as I always do when posters post these type of questions...and that is to flip it on me and ask me if its worth it to me...but I just wanted to get some opinions of others...I can tell you I am leaning heavily towards its not worth it...thus the reason my saleen 3.4 pulley and belt is for sale in the classifieds...any opinions and advice appreciated....TJ

Seth at Brenspeed told me I would get around 40-50 horse and 40-50 ft-lb of torque all the way from 2000 RPM to redline, and It will be very noticable. That with only 2 extra pounds of boost. I would do it.

I will let you know soon I'm going to the dyno this month with my 3.0 and 2.8 pulley to see what happens.

As they say....you have to pay to play. Like you said, is it really worth the $$ for the power return on it. The install is not hard. if you have any mechanical skills, you should be able to do the work yourself. The pump install takes more time than anything. It really is not difficult. Good luck!

hey tj, imo no it's not worth it.

if you go to the track, maybe

if it's just a cruiser, no

You're probably looking at about 40rwhp, but that's not the value of what you are doing. The value lies in the fact that you are giving your car incredible room to grow. Especially with the GT500 dual pump kit. Pull the trigger.

First off I'm not recommending anything, I'm just stating what I've done. I've had the 3.4 pulley on my car for around6 months with the KB boost apump pushing 8lbs of boost with 438 h.p. and 407torque zero problems. I then put the 3.2 pulley on which upped the boost to 10 lbs. and h.p. to 467 and torque to 441 with the KB bap, zero problems. I then had Brenspeed put a set of the NSR cams in which gave me 493 h.p. and 447 torque. Eventually I will purchase the GT 500 pump and the 60lb. injectors and a built bottom end, but for now I've had zero problems and drive the car like I stole it. It's all a personal preference and how comfortable you are with your tuner and your car. I think 10 lbs of boost and a good tune is safe, an awful lot of people on this forum run 10lbs of boost with zero problems, and yes eventually I will get the GT 500 pump. Good luck on whatever choice you choose.

i ran 10lbs with no problems on my stock fuel pump

Me too, but for some reason us turbo guys can stretch that stock fuel pump a little further.

I say leave the car where it is power wise and if you can upgrade your suspension, do that.

Keep it as it is right now ! Remember .... 426rwhp is more than enough for your stock tranny ! So if you get 40+rwhp youll be spending more than the fuel upgrade, you'll be a bit past the limit of the auto tranny and in red-zone for the stock internals aswell.
