First off let me give those of you a short summary of my kit and mods. The only mods I have beside the supercharger is PERRIN catback non-resonated, non-catted front pipe, and over pipe I have their oil cooler and air to oil separator. I received my kit in December of last year. I had PERRIN’S so for the first couple of months had a lot of different maps that mad great power and was happy with. But it just wasn’t enough being at such high altitude I didn’t see the same numbers a lot of you are with their tune. Here’s the dyno chart just for a refresher.

After running their tune I decide to go in my own direction with this kit. In order to run E-85 I went with Visconti’s 500cc fuel injectors and fuel pump. Also had a smaller pulley ship to me from Vortech. The smaller pulley didn’t make very much boost from the old one maybe .5 a lb. but the E-85 made good power with the kit. I thought this was it, didn’t think there was going to be anymore power come from this kit with out a compressor upgrade and some internal work to the engine.

Couple weeks later I received a call from Vortech asking me if I would like to send my blower back to get a compressor upgrade. Took me about an hour to have the blower off and at the ups store. Got the compressor back and reinstalled with a smaller pulley then what comes with the upgrade. Because of my high altitude to make more boost I went with a lower rev limit and a smaller pulley. After wait a long three to four week for the tuner to have some free time to get my car back on the dyno.

Coming into this I was expecting to be around 290-300hp maybe 200-210tq. Went to do the first pull and the car went lean at about 5500 rpms. Wish I had got these charts printed. But at 5500 the car made 250hp and 180tq. It took awhile to get the AFR right after a lot of tuning he finally got it right where we wanted it I can say I am very impressed with what Vortech. Once again it’s like a whole new car. The car made 365hp and 261tq with the rev limit being set at 7450rpms. It made 12.5 lb of boost. Now this is what I was looking for. I found myself asking the tuner if his dyno was broke. He reassured me it wasn’t and that it reads low compared to a lot of other dynos. After dialing the tune for about another hour it was good to go.

I planed on towing the car home but after see these numbers I just had to drive it home. Just form the drive home the car is amazing. You have power down low no need to down shift to pass. From 1000 to 5000 you can feel the torque your heads almost all the way back in the seat. But where the real power is, is from 4500 to redline WOW. Wish I were better at describing all this for those of you who don’t believe in this kit or have any doubt about it. It doesn’t give you the head jerking motion that a turbo do. It a nice smooth felling that happens very quickly. Next purchase is going to have to be tiers the tiers break loose in first second third and sometime four now. Hoping to get a couple in the car videos for you guys today. Hope this helps some of you out like I said I cant describe how amazing this kit is.
Big Thanks to Vortech, And The Boost Creep Ltd. for the tune. |
