I'm not sure what the problem is because the car seems to be running good. I just got my ECU back on Wednesday and I was very pleased at how I thought the car was running. I took her to the local drag strip last night and I did not have a good night. The best I could muster was a 14.2 at 93mph with a 1.9 60ft. This is significantly slower than when I was stock.

My current mods:
HKS racing suction intake
Walboro fuel pump
MBC
Dynoflash

I expected to be trapping around 104mph or so with times in the low 13's to high 12's. Any ideas.

 

maby your cluch is starting to go. even tho you may be making more power you cluch is going to slip a lil more. its a gess so dont hold me to it.

 

get a full exhaust

 

might have a small boost leak??

 

could be a boost leak, and maybe the clutch..but i think you'd notice the clutch slipping. check all your boost hoses...dude you should have gotten an exhaust before all that stuff

 

your shifting?

 

Its definately not the clutch. The car only has 3800 pretty conservatively driven miles on it. My exhaust is coming next week. I guess it could be a boost leak. I thought maybe it was the boost controller. Got a new Hallman pro on the way too.

 

shifting at 7200rpm. If anything I'm driving better than I was when I was stock. Even without the mods I should have seen some improvement based on driving alone.

 

yea, I would lean towards a boost leak for sure

 

Would a boost leak really cause that much of a drop in my trap speed? We're talking like 10mph or more lost.

 

Do you have a boost gauge?

 

yeah boost leaks can sap pretty much all of your power depending on how bad they are. Haha I've been N/A before when an IC hose popped off and I probably would have trapped around 70 mph...

 

yes...and the boost was a bit on the low side no matter what I did with MBC. I just dont see how a boost leak could cause that big of a loss in power.
