200rwkw In A 350gt

[bigc04]

Hey guys was just wondering if i were to modify my v35 what would i have to do to get around 200rwkw, would i need to do any major mods or are there light modifications i can make that will give me significant power gains? is there anyone on the forums that has made this kind of power without needing anything like a turbo kit/super charger?

Proper pod cai, plenum spacer, plugs, headers, high flow cats, catback exhaust, ecu flashed or piggybacked and possibly stage one cams. You may try to skip cams and do lightweight flywheel and underdrive pulleys.

You'd get similar "feel" if you change the final drive gearset btw.

[bigc04]

Oh nice! sounds attainable looks like ill have some saving to do though thanks for the input man

[Touge Kyousou]

No worries. Defintely attainable. There are some unopened de's going around with 190rwkw. You're just gonna need to do the last bolt ons available or pop in some drop in stage one cams so you won't need to touch the valves and springs.

It's what I was gonna do but alas I'm selling my v ATM.

I'm curious how it'd be with 200rwkw+ and swapped final drive gearset =O

[xscape237]

Thats a bit optimistic in my opinion.

Perhaps on a very happy dyno.

Also, the final drive WILL change the dyno reading, beacuse it is a reading of the power at the wheels (not the engine). Its the same as doing it in a lower or higher gear. So i'm not sure what you mean by "feel"?

I'm looking to get to that 200 mark aswel.

I had Spacer and Pop charger with Ztube and got 177rwkw. I now have Extractors and Grounding kit(I don't now if this gives you any more power but when i bought the kit it claimed 5hp) and i'm hoping to get 190rwkw with these new mods. Next is Exhuast and a Dyno Tune. Fingers crossed i get the 200rwkw.

Agreed. On a VQDE rolling a dyno dynamics dyno in shootout mode you will be hard pressed to make it to 200...maybe if you do everything and a 4.9 final drive. I've only heard of one VQDE making more than 200rwkw in NA, and it was an expensive exercise from what I hear, involving high-comp pistons and upgraded valvetrain.

[Touge Kyousou]

The final drive mod won't affect the kw atw reading too much. I've had runs done in 3rd and 4th in one of my previous cars and the kw reading was honestly about 3kw difference or so iirc.

When i said "feel" i meant the acceleration rate/g's pulled should be close-ish between a V35 with bolt ons and a V35 with mostly standard stuff and a final drive gearset.

I think full bolt ons and cams should just touch 200 but i may be wrong of course!

I've hit 182 on a dyno dynamics and that was with stock headers, cats, y pipe, airbox (but with ztube and panel filter) and pulleys still. Plus the y back exhaust i had was more tuned for sound than flow/power. Add headers, metal cats, y pipe, lightweight fly/pulleys and it should hit near 200 imho, drop some stage one cams and it will be there or over in my mind.

To the OP, just remember weight is the mainy enemy in the V. Look up Amuse 350z to see how the vq35 goes with bolt ons and much less weight..

Oic well if bolt on mods can at least get me close ill be happy i wouldnt say the power of a stock v35 is lacking just wouldnt mind having a bit more there for a little more fun i was under the impression an exhaust doesnt make too much of a difference but had planned on getting one for the sound anyway but if it does even better!

if you want 200rwkw i recon just hook up a 50 shot of NOS in a wet system... Im so going to do this when I have some spare $$$$ to blow on the car

[mattysaidso]

out of interest with 190-200rwkw in one of these, what sort of 1/4 mile times are atainable?

I totaly forgot..... I have Light Wieght Underdrive Pulleys aswell So i'm sure i'll get over 190rwkw. I'll see if i can get a dyno run next week.

around 13.9 seconds for a good run

mid to high 13's.

i have around 173rwkw and i've managed 14.26@100mph.

[180 wanabe]

I pulled a 14.5 up in Townsville in summer with a full tank of petrol and everything in the car "spare wheel jack etc" with 35 profile tyres pumped to 40PSI

Id say with less than 1/4 tank of petrol no crap in the boot and the stock wheels/tyres with a lower pressure as i did get wheel spin "lazy diff" perfect launch and a good reaction a flat 14 would be acheivable at around 170 to 175rwkw

Thats what I thought too after running a 14.85 sec best run last Dec with a totally stock (160rkw dyno dynamics shoot out mode) car. However experimenting with 1/8 tank of fuel and no boot contents (spare etc removed) has only resulted in shocking axle tramp untill tyre pressures are below 30psi and then dont seem to bite off the line. Will get new data next Sat from willowbank but 'seat of the pants' testing hints at slow hole shots from too light a rear end set up.

Reason I cited a 13.9 pass was that an aquaintance with a 200rwkw coupe got this time from his best run of the day a couple of years ago.

I have personal experience against a stroked (3.7 litre) coupe that could only manage a 15.50 sec pass same run as my 14.85. His was auto and a free wheeling diff (no lsd ) so attribute the slow time to traction issues.

[180 wanabe]

I think a LSD would make a fair difference to the Auto as far as traction goes, although its not like a V35 is going to have the traction problems of a 300rwkw S13...

Just got home from the Dyno and i got 191rwkw. Mods Popcharger with Z Tube, Plenum Spacer, light wieght Pulleys, Extractors and a Grounding kit.

I Dyno the car stock when i got it and had 163rwkw. So about 28kw of mods. 9 more to go

Getting closer there mate....

[bigc04]

oh nice thats a reasonable gain for the mods youve made impressive
