Ok i dont get it with a stock motor intake only i ran a 16.9 in 90 degree weather. Now i just forked out mad cash into my engine to get the mods below and i go to the track today to run in 50 degree weather and well before i tell you my time i know i feel a power difference. It feels like i have lots more power. but today i run a 17.4, what the ***** then a 17.2, 17.0, 17.1 and i just cant figure out what the ***** is up!! is it becuase i have not done any ECU tuning yet why o got why does my car hate me!!!! HELP

 

O for crap sakes, look at my mod list and trust me i did fine launching i tried every thing. All those mods all that money for what a tenth of a second added to my time ***** ME!!!!!

 

I was thinking could i be feeling more power becuase of an increase in torque. would i have to make some timing adjustments or something. someone who is smart help me figure out why my car feels faster but is not. its slower

 

Did you race before with your clutch and flywheel combo?

My friend who shall remain anonymous, ran a best of 15.4 in his car, but recently installed the clutch and flywheel combo and last night could not get below a 15.9!

And yeah...it sucks to fork out the dough only to be slower.

 

No the clutch and flywheel combo is part of the new run. Maybe that has something to do with it hmmmm but still a port and pollish and the cam shafts???

 

How could the clutch/flywheel make times slower? If the car was revved and launched well, and kept up in the high RPMs, wouldn't it help out? I don't get it...please inform me!

 

you also have to remember in 90 wether your tires are gona be stickier, and you you need to get a est 1/4 miles time on both the 50 degree run and 90 degree run. also did you have your coil overs on your first run b/c suspension does make a difference in drag racing. esp with take off. how high of rpms are you shifting at on the two differnet days.

 

also how many miles were on the car when you did the first runs and how many are on the new engine. some enginre require break in time before they become faster. wierd huh also have you dyno'd your car to make sure everything is working right??
and from what i've gathered from theman, you need the j-spec intake manifold for the cams to make a difference

 

yes i had the coilovers on both runs. the headwork was done by GTP in Texas the valve train components consisted of some better springs and retainers thats about it for that.

 

i agree.

FS-ZE manifold to be exact.

do a search, theman has a really good writeup on it.

 

So are you saying that without these upgrades i am not going to get better performance???

 

take out your AEM bypass.. you don't need that **** and if you wanted to get strait line times then you shoulda just got some nitrous

 

no exactly, look at the cams/manifold like this


aftermarket springs/struts

if you put the new springs on, the car handles better, but the stock struts(not in your case) and not designed for the spring. so to make the spring perform to its fullest, you need the new strut. the cams will work without the manifold, but you won't see HP increase from it. but it will puller all the way to redline though.

theman should post soon and tell you more about the manifold and cams b/c he knows it best

 

or he'll just yell at you to do a search, in typical edwin fashion

 

i dont want straight line times i just like to see that my $$$ is not worthlessly tossed away. I like my car for auto cross setup and have the suspension just perfect but speed is a bi product
