V36 370Gt Kws?

[xj265]

Hey,

I should start off by saying that I am looking at maybe getting a V36. I wanted to ask any V36 owners out there, who have been on a dyno how much power you guys are making?

And if any one has done any modifications ( catback exhaust, intake etc) or tuning (UpRev), how much difference did it make?

I apologise in advance if there is already a thread like this, please post a link to the thread if possible

Thankyou

[The Max]

I'll let you know when I get mine done in a month. I'm reverting mine back from UpRev Osiris to the original ROM because my tuner uses ECUtek.

friends one made 186rwkw on a hub dyno.

if your getting one get the 370SP model - really nice street / cruise car and great value for money.

PS - can always get the Infinity badge kit as well

[xj265]

Thanks for the replies guys

I should add I am aware of the G37 scene in the US, I just thought I would ask on here.

"The Max", please keep me updated, have you done any modifications?

and "maclarenf1", what mods has your friend done?

[maclarenf1]

K & N filter and nothing else.

[Wogboy]

185 @ the wheels, cold air fitted.

[xj265]

Thanks 'Wogboy', any mods for the future?

[Wogboy]

Has diferent exhaust for note. No other mods planed, i think they go pretty had as is.

[Colt357]

180kw on dynodynamics, 5spd auto and 20s 275 tyres

Whilst we're here... how about stock V35 350GT Coupe (Automatic) performance?

^^^

I bought my auto V35 350GT coupe from a specialist importer. Compared to all the others I test drove, mine seems to have a noticeable advantage in acceleration over the others.

The car was auction grade 4, other than a grounding kit, tein coilovers with EDFC and the factory powerduct (with K&N panel filter), the car is stock. There seems to be very touchy throttle response, particularly at low rpm. I cannot find out what could be generating the extra power! The dealer seemed to think it was chipped. I checked behind the passengers side panel, and the ECU is stock. Would there be any other way to see if it is chipped?

A friend seems to think it may even have upgraded cams- apparently this is pretty common in Japan as it gives them a bit more low down power and torque.

By comparison, I drove one (not from the importer, but someone who was selling privately) with a kinetix plenum, stillen induction and performance exhaust, and I think mine would leave it in the dust.

I haven't done a standing 0-100 yet, nor had it dyno tested.

...other than a grounding kit

^ This?

= Your reason for very responsive...?

[camr33]

Yeah I did a bit of research into grounding kits, and apparently they do wonders, particularly for autos. The thread I found was for a us website, I think it was g35driver.com

Someone asked if they actually do anything and the responses were all overwhelmingly positive.

Still, great car, ant it'll run rings around my old R34

I'm still yet know a person who has installed a grounding kit and had any impact outside auto shift firmness and placebo.

Placebo is a very powerful thing.. I read many many posts about people claiming Strut tower braces had 'significantly reduced' bodyroll. which a STB cannot possibly do.

[Wogboy]

i agree with the grounding kits, its all in your head. may improove autos shift, but i think they just make an engine bay look messy.

[Ben C34]

How do they improve the shift? I'm calling that's in your head also.

[colin.ssc]

Grounding kits work for auto boxes due to the bad factory grounding. It helps shift smoother and abit harder. Another thing I noticed was my audio got a tad louder. The guys down at the audio shop said it was the grounding that made it better. Who knows...As to gaining kW....I doubt it.

I dont think it makes it look messy....then again I made sure I hid the wires where I could...looks pretty much stock.

[camr33]

I didn't say the grounding kit helped with any extra kw, but it certainly seems to help with throttle response and shifting. Don't knock it til you've tried It

[camr33]

I wouldn't say its in my head, as I didn't know it had a grounding kit until after I bought it.

But it definitely had a definite power advantage over the others I drove, like I said- is there a way I can tell if it is chipped or has aftermarket cams

[sonicii]

I think the general sentament is the difference is not the grounding kit. something else has been done to it.. possibly a throttle controller installed which has changed the throttle body response vs pedal position. Could also have had a uprev tune, which uses the stock ECU.

Grounding kits will normally only help if you factory grounds are very poorly designed, or corroded/damaged. The extra grounding from the transmission casing to the engine/battery may help as the auto solenoids probably ground to the transmission casing, and the existing grounds are a source of voltage drop.

Did it accelerate better at full throttle, or did you just notice the throttle pedal response was different?
