My Dyno day results on Long tubes
I picked up about 50 hp over my last dyno but I am out of fuel ..Had to stop and only made 3-4 hot pulls. Man was it hot! Record heat and the weather station showed it to be "107 degree feel like heat".. Some of the guys were using ice to cool the motors and help thier numbers but I like my car tuned in real life.. Glad I did, as Jerry added 8% more fuel up top and no response. These power gains are through CATS and it is important for me to stay legal.
After testing these long tubes, I feel they are worth 60-70 RWHP over a stock exhaust system. I already had picked up 15 rwhp on taking stock cats off and adding race cats/x pipe last fall.
Second thing that could effect my numbers, is that I running stock air boxes again and my last numbers were with CF 82mm airbox. Never knew what the box was worth but it is gone now..
Third, my last dynos were done in cold weather, low humitity and IAT on the pulls were 30 degress lower!
Picked up some nice torque , even though many wrongly belive that we loose TQ with long tubes..
Whats next?? Well injectors and more tunning! My CL also has some brutal TCU torque mgt that needs to be corrected before my track times can really drop..The E55`s do not have this but I have it bad. Thinking of using a TCU code from an E55 and load it in my tcu..
Thanks to Jerry Thornton for a great tune day and Kurt Decker for use of his dyno / nice shop.. We had 6 e55`s, one c63 and one M5..

Glad to hear it Brooke! That's one strong running beast you have there and I'm glad you finally got your wish. I know you've been waiting a long time for these headers and I'm glad it all paid off. Once again congrats and unbelievable gains!!!!

Nice gains!
They are the Eurocharged LT`s but custom made with larger primaries and collector. I heard they are selling this larger size now..

Alan, thanks! This TCU TQ mgt has to be fixes, as it has been limiting my launch from the start now.. Sal helped me figure this out and a few test drives in Shardul`s car proved it.. I just call it launch control..
Sean , thanks man

Nice gains! Those headers look and perform amazing! I really would love to have Long tubes for my car! By chance do you know how your mods compare to Hadilaw's car? I noticed he mad 10 less HP and 2 less tq. I know he has a 185 but did he get LT for his?

Do not know about any TCU work from EC.
Our mods are simulair but still different.. He has no cats, kleeman mid tubes and a CF airbox. He also dynoed his car different than me on the numbers you listed. I was there to tune and not got for the best number I could get. I stopped after I saw that I was not getting enough fuel to feed the power the headers wanted to add.. Others on the board are also running low on fuel in this HP range.. I just post the information I have based on average pulls. Doing battery re-sets on the dyno or lot of ice will easilly make a 15HP difference...If you want small primaries and mid tube headers, then by all means go out and get them! That is what forums are all about, sort through the stories and build your car!
Hadi Law car is real strong but he is the one to ask about his car..
Oh yeah, he also had the double bag ice mod.

Thanks for the info, I Fully understand the Fuel issue and am working on mine, You may want to check your fuel pressure under load, if your car is like mine its not a issue with the injector as much as its a dropping fuel pressure. My base pressure is 77-80 and is down to 55-60 by 6200.

Thats cause your injectors are spraying harder at higher rpm's, thus the decrease in fuel pressure.
Problem with maxing out and swapping injectors is that your entire file will need to be re-mapped.
Thats the one mod that I dreaded the most because it took forever to get it dialed back in correctly.

What are your plans to fix the problem? Pat over at PTE suggested having the injectors clean, calibrated, and increase the the flow. This is by far the cheapest and IMO will resolve some of our issues. Just a thought and good luck!

This is very true Brooke. I'm running right on the border of running out of fuel but I think my 2.5" tubes are saving me from going over the top. There are several cars now in that same hp range running into the same issues. I was honestly thinking of going with 2.75" tubes as you know but the cost is really starting to add up. I just need to except my car and be happy with the performance I've been blessed with.

Ok, back to your question.. Fuel is tricky and you have to figure out if it is pump, line size, line restriction area, dirty parts, injectors or all the above.. Going to change fuel filter and then check fuel PSI. Injectors do not cost that much , if you don`t buy the SLR. Off the shelf injectors are in the 300 range, unless I am missing something. I am also looking at the kenny bell boost a pump but would prefer to get buy with injectors.. 48lb injectors seem to be the range I am looking for, maybe even 45lb..
I was hoping someone would chime in , that has done all this on our car already???????
Right now, I could give back some HP and fix this frickin CL Torque managment; then still ET a lot quicker.. My TQ mgt, is limiting my car from anything over a 1.72 -1.74 sixty.. More power helps on rolls but not helping much at the track.. Even with TCU off, I can hardly spin the tires in the water box...lol
