I see info for turbos coming out for the G37, but i dont see anything for super chargers.

I would think a super charger would help a G37 more than a turbo because of the torque problem iv been hearing about.

Was just wondering what others thought about this and if there is any rumors of super chargers coming out.

 

Turbo for sure. More power potential.

 

With the compression these motors have, I say neither. Unless you pick up a centrifugal SC with a custom pulley (bigger in size of course).

 

different strokes for different folks.... personally on this car turbo would be my choice...

 

I wish we could just add a chip like on some other cars and get 30+ HP lol, only a dream

 

FI + stock engine = BOOM! (unless you're talking about very low boost...which would be a complete waste).

I'd definitely lower the compression ratio before I'd even consider any kind of FI.

 

i would just rebuild the motor, just to be safe.

 

good god...there is so much mis-information out there it's unreal.

a supercharger would be great but stillen and vortech needs to see a strong market for the VQ37HR...so far it's in only one vehicle.

as far as turbos, twin turbos, stroker kits, etc. they are already in development. guys at Forged and GTM (known for helping the VQ 350Z/G35 guys with FI setups) have said the VQ37HR's internals look like they were made for boost, unlike the VQ35DE.

there are many cars with higher compression than the G37 and boosting well AND safe on their STOCK motors. go to any S2000 or E46 M3 even RSXs forum and you'll see. hell the 335i's engine comp ratio is 10: 2 :1...not exactly typical "boost friendly"...again this goes to fine tuning and internal engine strength.

i personally didn't like the stillen roots type blower. it gave great power down low but tapered off up top. i liked the vortech delivery better with it's centrifugal s/c. power was linear and "eased" the boost as the rpms went up.

remember F/I is supposed to compliment the car...not turn it into something else..if you do that then you would definatley need to do internals and hours of tuning.

 

From my 350 days, people running either the vortech or stillen/eaton basically had a stock car in terms of being a daily driver with 75-100 extra HP.

From there, the basic exhaust, pully upgrades will safely yield a mild gain in HP. Also a SC will add low and high end power. For a daily worry free driver I would say go SC. If you're looking for monster numbers and a skiddish driver go turbo.

I also like the vortech setup better than the stillen setup. I hope Vortech gets on this.

 

i've called technosquare fr reflashes...no one has donated or volunteered test cars
i've called vortech and they said 'it is on the works...but it depends on the market'

the VQ37HR is just not getting enough coverage yet...unlike the VQ35DE which was in almost every car nissan made...LOL.

 

Pay attention to where you are getting the information about the "VQ3.7" being better at accepting boost. It is in their best interest to tell you that, since they are selling FI kits

I'm also betting that most people who are looking into FI, don't want to do an entire engine rebuild. It takes more than "strong internals" to prevent detonation. High compression + boost = BOOM. Sooner rather than later. And it's not just blowing the motor. The life of the motor decreases a lot faster. You'll start seeing things like blowby, etc and eventually you start losing compression. Again, this is a lot less likely to happen on a car that was MADE to be boosted. Don't fall under the assumption that the only problem NA cars (which are boosted) face, many other problems can manifest themselves

The point is, if you want an FI car, buy a car that is FI from the factory. If not, exect to dump thousands and thousands into your car. Yes it will be fast, but you lost a lot of driveability, reliability and most importantly warranty.

 

i wish something similiar to the proced for 3 series. thing is a best gives owesome power, and not that much money. Its awesome. But then agian prob because the car it self comes with a turbo much easier to mod

 

i guess we agree to disagree. yes high compression engines are NOT IDEAL...but it does not mean high compression + boost=BOOM. that's a generality. again look into cars that have stock motors and high compression (again look into S2000s and M3s)...there are TONS that are boosting and are doing quite fine.

just because a car is run FI form the factory does not mean it is NOT prone to problems. that is ridiculous. do you know how many blown supras with the all legendary 2JGTE there were before somebody got the right tuning together to have them see 600whp?? it takes tuning and again (not trying to sound like a broken record) but 'WORK WITHIN THE LIMITS OF THE CAR'...some cars take 10psi well with a good tune...some can only take 6psi.

i was N/A with mods and my car was detonating like crazy because i was running VERY LEAN...my spark plugs actually has aluminum bits in them.what fixed it? TUNING. that applies to detonation on FI cars too.

people reading about blown motors need to see beyond just the compression...did they tune the car? did they tune it but added another thing to richen or lean the a/f ratio? are their seals okay? was the kit defective in that it caused PSI spikes?

i dunno man...i have witnessed and seen too many "high compression" engines last very long with a good psi set and good tune to advocate the whole "BOOM" thing...

 

I don't think we are totally disagreeing. I never said cars with FI were totally immune from problems. I said they are "less likely" to experience problems and it's true. And i was referring to stock boost levels. But since you brought up the supras..... Those supras you mentioned: Keep in mind they were running aftermarket turbo kits, which throws this whole argument out the window. Even factory FI cars well built like the R34 GTR and MKIV can only take so much boost. I have installed a few supercharger kits and even tuned them. And watched motors die overtime. These cars were very well tuned. I recorded injector pulse width, knock counts, timing retard. I verified everything to an ex-NHRA tuner. Motors with high compression (anything 9.5 and up) that are supercharged, are going to have decreased life. There is no way around it. Even with a perfect tune.

Regarding the 350z blown motors, there were roughly 30 people with blown engines. I'd say most were tuned by "reputable" tuners. 30 blown motors is a lot, considering a very very small percentage of 350z owners will actually add FI to a motor. If it were only 3 or 4 blown motors, I wouldn't have thought much about it. I had an old supercharged trans am which I tuned. Not one of the people on our forum ever blew a motor that I can remember. And since those cars were cheaper, a lot more people had FI. Just giving a comparison

In the end: I look at the Gcoupe as a sports luxury coupe, not meant to be "fast." It is certainly "quick" and faster than most cars. But it was not engineered to compete with Shelby Cobras, C5/C6's, RS4s and everything else that is meant to haul ***

 

at least we agree on that. people put too much weight into 1/4 mile and 0-60. i believe a car shoud fit the driver and that means meeting his 'intangible needs' that are not rated in stop watches...i mean the bimmer guys were always so against turbo cars and so into driving dynamics , the purist N/A motor experience, and handling....well now their 3 series has twins and the car they loathe, the G37S is the better handling car with the N/A motor...god is funny at times...
