I know a lot of you are already experiencing some winter temperatures, but here in the great city of Houston we are just getting into the low 60s at night. Figured I'd give some of our new bigger HP people some tips if they are new to their setups and turbos in general need to keep some things in mind.

The biggest thing is to pay attention to your boost controller for your peak boost you are seeing. When it gets colder you will notice a increase in the amount of boost you are seeing so you need to factor this in when you are selecting what type of fuel you plan on using. If you can adjust it I would recommend setting the boost controller for less than you normally do.

Example (Keep in mind I am running MS109 when this happened): During 80-90* weather I see 20.1psi peak when my boost controller's gain is maxed out. In the 70s it sees 21-22psi. Well on Saturday night I'm coming home and I start dicking around in 3rd gear. I hit it and was like holy **** this feels incredibly fast, because I have just started seeing more than 20psi because of my new intake tubes and the weather. So it felt fast at 22psi, but this felt even better. Well I look down and see my Peak Hold was 23.8psi and I was like because I had no clue it was going to do this. It was only 65* outside and I didn't think it would change that much so I had no clue what my A/Fs are. So I do the semi unsafe thing to do, because I was on a LONG stretch of road with nobody on it and no side streets. I picked up my A/F gauge and started watching it (it's about eye level with the road). I rolled into it 3rd gear again and the a/fs stay in the 11.6-11.9 (touched 12.1 during spool) and I look at my Peak Hold again expecting to see 23.x, but instead I see 24.9psi. The car felt incredible! I know its not safe, and I plan on dialing down my Boost Controller. I am guessing that 24.9psi (roughly 1.71bar) the car was making close to ~750+rwhp in the weather. It felt incredible, but thats playing on the edge right there!

I just want to warn people who are new to turbos (other than stock) and have some of these kits that use an aftermarket Electronic Boost Controller. Just be safe... I don't want to see any post from people about how they gernaded their motor because they didn't change their boost controller or had the right fuel for the amount of boost they are running. I myself forgot about it and I could have been in the same boat. Luckly though I run with my EBC off when I am on pump gas, so the boost stays at about 16-17psi.

 

thats funny u say this , cuase the other night leaving work ... it droped from 65 day time down to 46 night time . and same thing happen to me, car was running like a raped ape lol , im like wow , then i look down lol.... dialed it down.

Great Write Up

 

great write up. very true. i run 1.15 bar on 93.you need to constantly play with the greddy even if the weather goes up/down 5 degrees.

 

Great post, bro.

I always take for granted that modded TT owners have had experience with modified turbo cars before...but that's definitely not always the case. Great info.

 

I'm counting on the cold weather to trap 150+ at Milan in a couple weeks.

 

Brad,

Good luck, we are all rooting for a 150+ !!!!!!!!!!!

Powell,

great write up, as I played with my boost controller a bit the last few times out including hitting that dreaded most feared of all button, "Lo Boost" as I was in Wisconsin and had to fill up with 91 Octane at the pump. 1.1 bar peak for me on the
pump.

Thanks for that info. I had no idea about any of this. I just thought that "happy days" would come as soon as it cooled down a bit more and I was expecting the car to run even better/faster with the cold air. I already put a call into Akram to walk me through what I need to know about this. Thanks Powell.

 

oo yeah baby!! i should have my car up and running with the new intake maybe sunday decided to go with the protomotive full air kit with the ford maf hehe cant wait if not this weekend it will have to wait till i get back from sema

 

TIM LOL you took my advice ?? thats great.. its gonna be scary man...

BTW i took care of bussines the other day , it finaly went down... mark one down for the 20s.

 

To the top again for the people who didn't get on yesterday.
