Hi guys, as you are seeing my signature you know what type of car do i own. I have been back from the drag strip and i am not so much happy with my times. Wright now i am running on just 6.5psi of boost with 9.1 compression pistons and a spoon head gasket . My times were: 60feet : 2.167 on 584mm semi slicks tires.
top speed of 109.56mph
e/t of 13.145
I have dynoed my car 2 days before trying the car and regards horsepower it leaded up to 243 whp. As i noticed while driving my car, i can feel that 1 and 2 gear are very powerfull but as soon as i shift in 3 gear and in 4 gear at 6500 rpm -7500 the car is not so much powerfull , but as soon as it reaches 7500rpm i gain a lot of power again till the red line is reached at 8900 rpm. Do you think that it is turbo lag because i have lowered my compression? {For you info my turbo size is t04/t3} And Please could you give me some advise about my drag strip times on this sort of boost and power? because i am a little bit disappionted on my time!

 

Post the dyno graph.

Who did your tuning?

 

I m sorry he did not give me any graphs. But we did not tune anything because i am still using a normal drag 12.1 a/f , fmu. We just checked what was happening with the w02 sensor and everything was looking good. Any Idea?

12:1 FMU? That could explain a few things. First of all, your tuner "should" have gave you a dyno sheet. He "should" have also given you your A/F ratio graph that goes along with the dyno sheet. This will help give you something to look at and compare for your next dyno run. How else do you suppose to tune without some sort of reference to begin with?

But from what it sounds like, you're probably drowning with fuel up top. Save up and ditch the FMU/inline pump fuel setup.

 

Yeah, I see from your sig you have a Darton sleeved bottom end. Sell the FMU and intank pimp then buy some real fuel management. All thats left is to turn up the boost. You might want a better tuner also. Not really alot of tuning you can do with a 12:1 fmu as your fuel management. Are you using something to lean out your injectors?? 440cc injectors+ 12:1 FMU= very rich and barely idling.

 

Your time and especially your mph is good for the power you're making. Usually integras need upper 200's whp to hit 109-110 mph. Why are you still using the FMU setup with a fully built motor? Your built type-r has potential to be easily in the 11's on slicks. Get some bigger injectors, 720cc minimum and a tuning system like Hondata or AEMS.

As for the dip in power, it's hard for us to tell without a dyno graph with a/f.

 

Thanks a lot guys for your help , but i have not fitted the 440cc injectors yet, i am still on stock injectors, that is why i am still runing 6 psi. I cannot work with those because i am still runing on the stock ecu, and for now i am very broke i have spent too much money to rebuild my motor . thanks again.
