finally got to dyno

[1989Gt.]

So the car made a tad less then I was hopeing for but its good enough for me. Next is nitrous car made 246hp and 240trq first run under gt tune.

Then the next 5 hr tweaked the parameters and it climbed up to 285hp and 290torque to the wheels I wanted 300 so bad but all the car has is h pipe borla side exhaust and jlt Cai. Built bottom end with 10.8:1 compression.

Not bad squeezing that much out. Throw a 20 shot on there and call it a day!

 

[1989Gt.]

Yea plan to do 125 shot in the future

 

[ZeroDCX]

How's it pulling with the new tune compared to the gt tune?

 

[1989Gt.]

A crap load better!

 

[SteedaX47]

4.6? What intake/head combo?

 

[1989Gt.]

Cobra intake cobra cams.

 

[SteedaX47]

gotta lovr compression lol. Nice numbers for little mods

 

[1989Gt.]

Will pulleys net me anything?

As far as my experience goes... a little actually. I only have experience with bbk underdrives though. Supposedly the steeda ones feel better. But the biggest reason why they're wanted is cause people don't like the piggy back system that the bbk and others use. Also my experience is with a 2v. On the dyno it helped throughout the whole range. Only like 2-5 hp but still. Not bad for 200 or less. Plus a quicker rev too. I plan on keeing the underdrives with my swap

 

[1989Gt.]

Oh yea my buddy picked up 8 or so with his steeda set. I was just wondering of it would be the same as 4v

 

[SteedaX47]

Probably around the same. Specially since the whole valvetrain takes away so much power. Wouldn't be surprised if they're worth more on a 4v lol. Id say id post the difference but ill be starting with them directly with my swap lol. I'm hoping to be at least 250-260 rwhp N/A without boost but I won't know for sure since the turbos already on the car lol

I would say do a shortrunner intake and headers, I have a shortrunner on mine and it made a huge difference.

I don't understanf why you couldn't squeeze more power out. On my old cobra I was running 10.5:1 compression wih only a x-pype, steeda pulleys, and a k&n air filter and I made 300/300.

Different dyno, different day.

Verrry good point sir. Something often forgotten

 

[1989Gt.]

It was 75 degrees and 35% humidity dynoojet. I was at 290 whp but he said still had to much timing up top he said that the less timing thebetter for the engine

 

[DVJ38]

Yes, you do gain a few ponies. March makes a set for our cobras that I hear are pretty good.
