What's with the vibration at higher rpm & the overheating. I didn't have that.

It came with the VVEL.

I have never had an issue with high rpm vibration, dont know what that is but i can tell you the hr runs just as hot as the vhr you just dont have an oil temp guage in the 350

Could be. Now you tell me

1slow370 · 10-29-2013, 01:26 PM

Because the 350 has no temp sensor there is no limp mode for high oil temps. So it "wasn't a problem" before

From what I remember in my previous roadster HR. I installed an oil temp gauge and a medium sized oil cooler .... I never had big heat issue as I got with the VHR on bigger oil cooler setup
So yeah the vhr generate a ton more heat principlay from those VVEL heads

1slow370 · 10-30-2013, 02:30 AM

The hr's had the water oil cooler installed from the factory too. And after adding it in '12 the vhr has much less issues with temps.

I guess not every HR because my roadster didnt.
Im just comparing my previous HR with the VHR setup I had. My point is the hr ran cooler than my vhr.

1slow370 · 10-30-2013, 02:36 AM

The vvel systemdoes generate more heat, but in reality it isnt a whole lot more. Most of the heat that goes into the oil comes from the pistons, cylinder walls, and rotating assembly. There is very little that comes from the heads in comparison. Most of "the vhr runs hotter" comes from the missing factory cooler not the engine itself.

first of all this thread is stupid. I owned at 03 350z, a de, and compared to the 370z that car was a like a daewoo in terms of fit finish and quality of materials....In terms of speed/times, without the same driver at the same track you will never get a true comparison. With that said, it is preference, but the 370 is a better car, it released with a declining economy and a msrp too high...it crippled the 370z...with that said, I have run the 1/4 mile in both my cars, and I admit I am a terible driver, but our track sucks too, everyone consitantly runs slower there, my buddy has an 11 second srt-4, by 11 I mean consisant 11.04-11.1 only runs 11.4-11.7 at our track...Before I sold my full bolt on 03 tuned by RT I ran a best time ofd 13.6... I took my 370z there this year and best time with bolt ons and no tune was 13.7, it was deplorable and my drving was horrid, I know that...so these results my 350z is faster than my 370(which is now tuned to 322whp, the de had 252whp) My DE would not touch a new 5.0 mustang, lets just say the 370 was raced at the "track" against a new 5.0 several times and my Z was victourious each run. Spatting off track times are usless is my point, get whichever car you like.

You beat the new 5.0? The owner probably didn't know how to drive -

They consistently run around 12.6 don't they?

andre12031948 · 10-30-2013, 10:06 AM

Should not even be in this thread!

I beat EVERY STOCK, only tuned Mustang at the track. The best one's in stock form did 12'6's. Which is way better than any tune stock Z. My car was tuned & mildly moded.

ITS FOR COMPARISON PURPOSES OF FACTUAL DATA NOT ALL THIS HYPOTHEICAL BANTER.

Again, we did it multiple times to be sure, not saying I blew his doors off but it was stock. A friend of a friend has a 12 stang with intake exhuast and a flash, his best run was 12.6 at our track, consitent at 12.8. Before my headers and tune just to give your a mental picture that car would be Id say a little over a car length in front of me on a legitimate race -closed course simulated street racing from a 40 mph to 120 mph, at which point we were side by side until I hit 4th gear, the 370 falls flat...but it is much better in that area now that it is tuned. Next year when we go to the races I expect to be pretty even, I think from a legit 1/4 dead stop he will prevail, I expect to be around 13 flat if I learn to 1/4 mile drag.

My whole point is get the car you LIKE, if you LIKE the 350 get it, put money into it if you want it faster, end of story, but in direct comparision 370z>350z OVERALL.

For the tenth time,
The 370 has more H.P. & potentials than a 350hr does. Also 350 de cars should not be in the mix. I think I'm done here...
