G5x3 Results Inside.
Well I'm going to drop by LG next week to see what LG thinks.

I'll let the #'s speak for themselves.

Before:

228/228 588/588 114+4

376 HP / 367TQ
I dont remember what timing was set at.

After:
Only performance mods added were G5x3 and ASP UD Pulley.

2??/2?? Duration & 600/610 Lift at 114+4

385 HP / 360 TQ

26 degrees timing for N20

I know #'s arent everything but I am a little disappointed. Tomorrow I'll fill the bottle up and see what she'll do.

The rest of my setup is in the sig.

 

List you Mods an transmission/drivetrain.
Then whats the AFR
And if ya have a graph that would really help.

I dont have a scanner, but I will take a pic of it tomorrow and post up.

 

 

here's a pic of the graph

 

that 12 bolt w/ 4.10's will eat up around 10rwhp but its worth it when u're getting down the track

 

this was the last dyno w/ the 228/228 cam.

 

Acutally going from the 10-bolt to the 12, i only lost 5 RWHP, but i did lose 25 ft/lbs of TQ.

I just dont think that going from a 228/228 to the G5x3 would have only picked me up 9 HP and a lose of 6 ft/lbs of TQ.

Also remember I added the ASP UD pulley too!

 

I did 392rwhp with my G5X3 at Fastech

 

Its all good. Go down the track and see the results The hell with the dyno #'s. Did Chris robinson tune it?

 

yeah chris r. tuned it.

I'm setting up a race today, w/ the old cam me and my buddy were dead even from a 50 punch, so we'll see what happens this afternoon.

 

Let us know how that race turns out....should be in your favor. Anyways, look at it this way, you have more top end and that torque looks really nice. I think it'll prove to be worth it.

 

Did you do any data logging for KR?

 

something is off, 350rwtq @ 4k and a peak @ 6200.

 

Was the cam degreed in? Are you still running the 918's?

 

i have no clue how the tuning was set up, i didnt get there until it was off the dyno rack and on the ground.

i'm running PRC v. springs now.

 

Time to do a comprtion test. Do you have cats. What wheels and DS do u have. If u have 18in wheels and a steal drive shaft and a 12bolt with 4.11 you can eat up some power. Maby 20-30hp if not more if you have cats and some heave Drive train parts.

Think about it.

 

i have 17 in wheels, 3 in steel DS and no cats... but with the 228 i pulled 376, it just doesnt make since to go from 228/228 588/588 to the g5x3 PLUS a asp UD pulley and gain only 10 HP and lose 6 TQ. i am going to do a compression test this week.

 

The numbers don't sound too bad, honestly... as long as you have some stuff that eats up HP on a dyno. For instance, I dynoed 381 rwhp and 351 rwtq with my TSP 231/237 cam.

Full bolt-ons only I did 336 rwhp, 336 rwtq, which was with an ORY, but dynoing through a 12 bolt with 33 spline Eaton posi and 4.11 gears. So my car dynoed low to begin with...

Also, in addition to adding the cam between dynos for me, I also added a heavy Denny's NR driveshaft, went from 16" wheels to 17" wheels, and added a catted y-pipe... all of which can take away power.

Had I dynoed with my old 16" wheels, the stock aluminum driveshaft, ORY, and a 10 bolt with 3.42s, I wouldn't be surprised at all if I hit 400 rwhp and 375 rwtq. But all those other things I added are for getting down the track, not for big dyno numbers...
