4,000' ASL also makes a huge difference,

I have to agree with BoostedWs7... Ive seen a stock Firehawk even with stock exhaust manifolds and cats through a full exhaust dyno 460rwhp. This was with a ATI setup... with the stock ATI twin side mount ICs.

BTW.. I decided on the ATI over the STS for a couple reasons. 1) My tuner installed a STS kit on one of his customers cars and was kinda impressed with the kit but it seems to make really good numbers you need to upgrade the turbo, add a BOV, add either meth or IC to it, and then to add to it when he went to tune it he found that the location of the MAF was getting some turbulance causing tuning issues. (not saying this happens with all STS kits) 2) All the STS equipt vehicles around here, from what Ive seen, have had issues, in one way or another. They are very impressive when they are running. Water in the motor from wet conditions, motors getting hurt, etc. 3) ATI is a tried and true kit.. and to top it off you can get a smog legal kit and here in CA that kinda matters to me. (Even though Im gonna pass a D1SC off as a P1SC ) 4) The whole "use the piping for a SFC" kinda makes me laugh... and I dont want to give up my already welded in SFCs 5) I already have LTs and Y pipe, good foundation for the SC 6) The issues with belt slip are coming to an end.. ATI is developing a new bracket that will use a shorter belt, a TON more belt wrap, and I think it should be available very soon. Ive already seen one on a car.. the first one ever to be tested outside of ATIs place... and it works WELL!

Not to mention I get all my ATI stuff at cost too.. trust me though thats NOT why I went ATI. I also had a chance to get a STS kit, with upgraded parts, for cost as well.

Ive always been impressed with the Procharger stuff.... but dont get me wrong Im impressed with the STS stuff too.. it just wasnt for me.

is your procharger on yet? Cause if it aint your in for a big surprise with cruise buck I spent 540 bucks FROM ATI THEMSELVES cause they know theres cruisebuck at 3k but they tell everyone to live with it unless you want to run a bypass on each side of the air box with the race ready bov as well like I did. Also there intercoolers are complete **** after 580 rwhp. They are however supposed to be making new ones that are thicker and better. I would get those if I were you or fmic the kit. Thats the best way to go. As for water, well unless your moving your filter, get used to more water cause I got water from the d1 as well. I never had many issues with the belt so cant complain there. I got slip but nothing to be concerned with. As for the sts maf, works ok on some cars an not ok on others. I moved my maf which was no big deal but your still correct. There are sometimes issues with that.

I actually pieced my ATI kit together.. Ive heard of the surging problem but Im going to use a OBX FMIC with a Vortech Race BPV. I did hear about the thicker twins.. I guess they will be used only on the Vette kits from what Ive heard. The place I bought all my parts from wanted me to get the thicker twins and try em out but I had already bought the OBX.... and I think the OBX may work a little better anyways.

your all set then man, the obx is great and so isnt the bypass you got. Should be sweet and pretty issue free

damn i wish i'd want with the sts turbo kit.

Avengeance, How are you going to get your LT's to pass California inspection? If you can get them to look past that, they will look past wether it is a P1 or a D1.
And I really wish STS would put a fire under their respective butts and finish getting their CARB cert. Then I think it will be the only aftermarket Turbo that can pass a Cali smog inspetion (that I know of).
I thought the filter from the ATI was pretty low too? How close to the ground is it in inches?

Thanks for the good info.

I will take the brutal midrange please. I am assuming that is the STS unit?

My LTs wont pass inspection... I still have my stock stuff for when that comes around. Ive heard of people passing a D1 off as a P1 often enough. I have another trick up my sleeve too.

I hear you about STS.. I emailed them towards the end of 04 and they told me that they were anticipating a carb cert early 05.. still not here though.

The ATI filter is pretty low.. but from what Ive seen its kinda tucked behind the front end. Of course it would be a problem in a good size puddle but from normal rain I dont think it would be a problem. My friends STS Z71, some of you know him as F8L Z71, drove through a storm we had here and even on low boost, Im pretty sure it was low *5psi*, sucked up some water and had to drain his FMIC.

Any turbo kit... Thats how turbos act unless u run a really large turbo then u will get all the power in the topend.

Thanks for all your help. Its now clear as mud as to the appropriate kit. Seems the STS gives fantastic mileage 30 mpg.

I rarely had a water issue with the ATI but it can happen when you run a huge filter. My sts got me good in a rain storm which I had to also drain my fmic but I was an idiot since I got caught without the filter jacket. Im building a shield for mine just in case.

I'm not sure, but I thought F8L said he was on high boost with no sock.

Yeah sts does sound moure fun..I mean the feeling of putting you back in the seat almost instantly compare to gradually...

Ok I am sold on TURBO's I have two brand new old school Roto Master T04B's STS said that they would not work with there kit. Any ideas?

I'm going the same route as Avengeance. There are shops that will build a custom kit with a custom FMIC, 8 rib, etc. for under 5K. I already have the fuel system, headers, 4.11 gears anyway. If I went turbo (which is still a small possibility), I'd go front mount, but the extra cost would be to far off what I want to spend right now. Anyway, I respect the opinion of those that have had both turbo and super, but would I be dissapointed in a supercharger if I got it? Or would I be happy with it, but happier with a turbo?

Thanks for starting this thread, I've been pulling hair out trying to figure out which way to go myself for the last 3 months.

If you live in the Bay area, you should see about getting a ride in each one before you make up your mind. I know there are guys on this board with each kit that live up there. Check with Synergie, they might help.
$5K is a lot of money for any kit, and I think you would be upset with yourself if you decided you got the wrong kit. If there is such a thing
Post in the Western section, maybe attend a get together. I think in any case, with either kit, you will have fun.

I've actually been talking to Rick at Synergy about the kit. I have not made up my mind yet completely, but will be stopping by to see rick and look at his car. I've owned turbo vehicles before, but not SC. 5K is nothing compared to a good front mount setup though, whats the PTK go for, like 7K with a turbo?TTI? Speed INC? All real pricey, but gotta pay to play as it goes I guess.

Nick you foo! I was on high boost with no sock and the oversized air filter. :p

I ran around with the small filter, the sock and 5psi and and I had zero issues.

IMO you need to do something about the filter concering water on both kits if you wanna be worry free.


As for Dan, he is very well versed in the F-body world and drag racing in general and I think the ATI kit (peiced together like Avengeance is doing) is the best bet for his needs unless he wants to spend the money on a front mount which is superior IMO.

That was the day it was like a Monsoon leaving Ricks shop right? You dipstick... no wonder you sucked up water!
