Getting dyno done on stock 5AT 2004 g35c.
then w/
an new catback exhaust system by arkspeedracing.com
then w/
Fast intentions test pipe (resinated).

I will be leaving my motordyne 5/16 spacer on with ztube and k&n drop in filter

 

def post wut u came out with... i got a 05AT coupe.. i want to see where ur at

 

is it stock now and then u will be installing all the parts again? or do u already have the spacers and ztube on your car?

 

232Hps

 

just came back after dyno's. I will post the print out as soon as I get them. I did get 228hp with test pipe (fast intentions resin.), motordyne 5/16 spacer and ztube k&n drop in. first run 228, then 230 and 232. After I installed the full exhaust from Ark, 234, 236, 236 & 237. The dyno was done without any ecu reset and the exhaust was right out of the box. The numbers should be better after the muffler is tweeked a bit. The did'nt have the exact muffler and had to use a modified nsx muffler.

 

nice........good to see the mods work!

 

I used to get resinated from my pipe, but my job tests for that now.

 

Great work..... is your exhaust single or dual? stock 5AT is around 222-225hps...so you gain about ~10hps with those mods.....

 

that exhaust gave u a bump.. great to see gains... ull gain more as the new parts break in...

 

The exhaust is a single with y pipe, mid pipe and muffler. Quality is pretty good.
The guy at www.arkspeedracing.com is wanting around $1,200.00 for the full set but I am trying to get a special price for the forum.

 

I cant believe how hard it is to mod an AT. With all those mods to only equal to the hp of a stock MT g35.

 

^^^stock 6MT (03-04) dynoed around 225~228 max.....

 

Mt should get what tofu states. A stock 5at should get around 200-212 max.
I am getting about 25 more HP with the test pipe, spacer & exhaust. Which is good to see that they are actually working.

 

+05 MT make around 230-240. I'm AT also and when I only had kinetix cat and kinetix intake manifold (not ssv) I made around 232hp which to me blows. Since then I changed combinations and added almost all the possible bolt ons and still I was only able to net 250 hp. NA blows for AT and I wish I didn't waste the NA parts and gone FI fromt the start.

 

05+ 6MT stock dyno arround 245-247hp (same engine as the 06 6MT = 245hps).... we dynoed it on a very hot day (91F).
