I got Motordyne e370 installed at Jotech yesterday and my car already had Stillen Gen3 and Motordyne ART pipes. Everything went smooth except few fitment issues but a not big deal .. just took a bit longer, that's it.

First impression:

1. Workmanship is good (was expecting better)
2. The exhaust installed fairly easy except few hiccup.
3. The resonator cans look flatter than the older version

First startup:

1. One word FREAKINGLOUD!!!! It was monster loud.
2. When the car was getting dyno'd I had to step out of there coz it was so loud.
3. I almost forgot to mention the best part.... NO RASP!!! NO RASP AT ALL!!! One thing I am very very happy about.

Dyno Results:

Really disappointing . I am sure something was not right yesterday. 25 pulls after, the top number was 295 WHP which is unheard of considering the mods I have.. Going back in 2 weeks to get it retuned. I just hope it gets quieter a little bit.. Not that I don't love it but I dont want to wake up my neighbors every morning when I go to work

Damn that thing sounds beastly! Yeah you have to be careful what CBE you choose when you have test or ART pipes. I ran the invidia system because its super quiet. With test pipes its just right

295whp isn't bad though! 295-300 is typical for those mods. You have to remember you are running 20" wheels. For some more power check out the motordyne intake manifold or a lightweight flywheel if you have a 6mt.

 

Very nice... sounds good!

 

Really ?? 295-300 for Gen3's TP's, intake mani and CBE ?? I have seen 300WHP (298-297) with just Gen 3's and CBE. Myself included made those numbers, when I install my RHFC's and get retuned I'm shooting for 310WHP ;/

 

He doesn't have an intake mani. He just has the E370 which is the exhaust. With the M370 manifold he would no doubt see 300hp+

 

Correct.

Hopefully the sound will come down a notch... be perfect! i've heard with manifold you actually lose power than making it but surely look into lightweight flywheels tho. Thanks!
Thank you Sir!

Lucky you! I was hoping at least 310 or least 305+.. just wasn't my day. I am hoping to get those numbers after the second "retune", will update..

 

Opps sorry man, Though it said M370, DUR :/.. .

 

That sounds heavenly and that is a bad *** picture with the GT-R in the background!

 

Thank you sir! They had 6/7 GTRs laying around .. like it was nothing lol..
Every time I go there I can't help Drool over GT1000Rs they got in there.

 

Disappointed with 295? What are you expecting. Sounds pretty fair/normal numbers to me. I made 282 with stillen gen 3 / catback. What's your torque like? How much did Jotech charge for the exhaust labor and 25 dyno pulls?

Love the rolled titanium tips though. Sounds loud as hell. No more rasp?

 

LOL. Yeah a little, even the tuner was surprised that the numbers were this low. He did 25 pulls trying everything he could. We were pushing for over 310. Mind you, I have UpRev too... that's 20 gain(at least)

Going by Manufacture claims-

Gen3: 18hp
ART : 15 hp
e370 : 10 hp
UpRev: 20 hp
Stock: 330 hp
---------------
Total: 393 hp crank.. at least...314.4 to the wheels considering 20% loss..

IDK i might've higher expectation but 305 would have been a "Happy" point.
He gave me a good deal since I had the car tuned there initially. Exhaust install + tune + dyno was $300. Thomas spend over 5 hrs on my car.. I am they lost money on this one.. That's not even it.. They gonna retune it in couple of weeks and redyno in the price included. I feel like I really got a good hookup on this one.. They good people.

 

^ associative property of math does not apply to bolt-ons, i.e., gen3+art+e370+tune is not going to give you +(18+15+10+20)hp (even if you 'adjust' for drivetrain loss by *0.8). diminishing returns in addition to the heavy wheels you're running may explain your numbers. goodluck with your goals

 

jujubii is right. you cant add the numbers like that. plus those numbers are usually exaggerated from the manufacturer. Get some light weight 19s and a lightweight flywheel and you will see a big difference.

 

Hmmm..

 

Vossens are hurting you but you have to go off of what your stock run was before mods. You can probably bring it another dyno and see 320 or a different one and see 280.
