Air intakes help much?
I'm wondering if these help much and if so what brands are people using. For the most part the popular ones I see are renntech cf air boxes, speedriven scorpion intakes and bmc drop in filters. Anyone have experience with them and what kind of gains did you see?

It's debatable as to if it'll suck in hot air but it lets cool air in to the whole engine compartment now from the front.. I'm thinking that is a good thing versus less cool air circulating..
Pretty happy with the response time, but I might put the intakes hoses back on to see if there is any difference. I'm also thinking of dremeling two of the air redirect blades that sticks infront of the intakes that redirects the air flow towards the radiator section..so more air flows into the intakes hoses.
I'm sticking with the stock paper filter, it's fine..

hmmm ok. Back in the day I heard that the renntech cf airbox ads some good power so I'm also wondering about the scorpion from speedriven and if there's anything else out there. I hear our factory airboxes suck but who knows???

I'm still thinking of getting Speedriven intercooler / Scorpion kit.. or mod something similar. I love that carbon fiber cover.. hate to lose it.
Wonder if I can get bigger intercoolers, remove the airbox and still keep the carbon fiber cover..

. The IC's would basically just help keep it cooler longer so that the car runs more consistently so I doubt they would offer any significant power by themselves. So most of the power would have to come from the intakes and tune. Right now with the tune only I should be around 660hp therefore if the kit brings it to 750 it equates to 90hp more for $5k. hmmmmm.....

I'm actually thinking about getting the same kit too! But this really sucks with 91 crap gas the cars respond so much better to 93. The 800hp claim is on 93 so with 91 so I bet we would be around 750hp. However, I just went to their site and it shows the kit is a 750hp kit not an 800hp kit as listed here .

Best to add better HE at the same time.

I heard that the 65 HE is larger than the 600s and would be good enough for this power level. I don't know if this is true or not but just what I've been told.

A supplemental H/E can be added up front by relocating the oil cooler closer to the lower grille, it will give more surface and a small addition to fluid capacity. As far as the air intake setup, you can remove the two louvered pieced by popping the clips off the bumper support and save them to re-install if needed. I think they are more to prevent rain from entering and my car is a dry weather only car. You should consider how changing the intake drastically along with larger I/Cs can require a new tune to adjust for the additional air. That along with high flow cats becomes the next step in opening up both ends of the turbo. As for me I have the bmc filters but no comparison data.

ok thanks for the info. I've been told that the HE on our cars are big enough for our stock turbos so I think I will leave it alone and if anything just get a trunk mounted reservoir which will increase the coolant capacity by a ton. Plus I'd be able to put ice in it if needed and no more bleeding hassles of a closed loop system.
What mods and set up did you do to run your times and what gas did you use?

i am not sure how much it costs for the trunk mount kit but i am pretty sure that if you spent 2-300 dollars more you can get a upgraded front cooler, i also think plumbling 20 feet of hoses from the front to the rear is a bit odd... i would love to convert my washer fluid container in to the " trunk mount " if u need a direct bolt on upgraded front cooler let me know i think it is around $700

Even with stock turbos, there is still not enough cooling. Maybe in mild weather and without a tune, but once you have a tune and its above 80 outside you can really feel the effects of heat on back to back pulls. I have a Eurocharged ECU/TCU along with a Supplemental HE and cm-30 pump. The 11.34 was on michelin PS2's without the TCU and the 11.14 was with mickey thompson drag radials after a hot lap. From what I gather there is much to gain with the trunk reservoir, but don't think its maintenance free. I thought of having a drum shaped tank made to fit inside the spare tire to avoid removing it and being without. Also you will need to drill holes out of the trunk for the lines in and out and also to allow for a drain. If you are using ice it will melt and warm up after a few pulls. If you are leaving the car to sit between pulls it allows the lines that are routed across the heads to absorb the engine heat. So the ice is only so good then you need to drain the warm water to add more. Last thing about the ice is for the winter you need to refill with coolant if you are in the north like myself . In the end it helps but its not perfect and there are these things to consider.

But a bigger HE does sound nice. How much bigger is it than our 65 HE and do you have any pics?

i am going to my friends mercedes race shop here in los angeles to have the bigger heat exchanger installed soon, i will take pics and show you.... also as we all know it is very comman to have air in the turbos cooling system and air in the system will cause misfires, i can just imagine how many people will install this trunk unit and not have the system with 20 feet of hose bled properly.. or whillle they change there ice water they might end up putting air in the system...

I ran a few gallons of 100 octane. If you take the time to run the lines to the trunk, you may want to consider new lines up top over and around the strut towers as opposed to leaving the stock metal lines that cross over the heads in place for heat transfer. There is a post about it from jaycl600.

I had a few people pm me with questions about the trunk mount tank so I thought I'd just post here so everyone can see. First of all, I don't have it yet its just something I was thinking about getting. Some asked if plumbing from back to front would cause problems. Its really not a big deal and I don't foresee any problems. Others asked about bleeding the system. With a trunk tank you don't have to bleed the system its now an open system unlike our stock closed system. So no more bleeding issues.
One other thing I'd like to ad which is my own personal preference. For me I would rather have the trunk tank than convert my washer reservoir to one. For one our cars are nose heavy so if I had to put weight in the car its best to put it in the rear. Also the trunk tanks are 5 gallons which is way more than the washer would hold so fluid capacity would be greatly increased. The trunk tanks have the pump mounted to them so its now easy to change if/when the pump dies. With the washer you'd have to plumb it where the pump sucks from the reservoir not pushes through it.
The trunk tanks are nothing new we use these all the time in drag racing for forced induction cars. They are proven systems. Chiseled performance is a very popular company and they can custom make anything you want.
