How much boost pressure can a built VQ37VHR withstand?

1slow370 · 11-04-2014, 09:24 PM

Eh to each his own i would rather have a car that can easily hook up what it has than one i have to contantly hold back. A 450hp z runs mid to low 12's a 700hp z runs low 12's. Up to 125mph its the same ****. One is just a lot easier to drive.

Yes and no. If you're full throttle you will blow all 3 gears with normal street tires.

I for one can get traction peddleing 1st and 2nd gear catching at the end around50ish MPH. Just my experince.

10psi 480whp/450wtq is the perfect street use power. Just enough to run decent 11's with good driver or enough to blow the doors off a C7 on a 40 to 120mph pull.

It's your build, your goals. VQ37HR don't need to be built.

I'm running normal 245/19 street tries that are 10.5 inches wide. At 13 PSI you're applying 550 to 600whp.
A) You're either running slicks or very warm drag radials
B) Have VDC on
C) Roll throttling letting off before you spin

Either way @ 13 PSI 0 spin at 30 to 170 is great, but I was implying 0 to 50mph which is something total different. If you can do a 1.6 60ft 0 spinning then post a video and teach me the ways O great one. If you can't then your statement is total irravanlent no offensive.

If you're compaing drag its all about the 60ft. You can obtain faster times with a lower trap great 60ft v.s. bad 60 foot but high trap. Just means your HP is doing the work over the lack of driving.

Everyone here i'm sure is a great driver and im the last person to give advice. Just pointing out facts. At 0ft i'm spinning, not by much cause im peddleing or roll throttling but still spinning. Anyone that can 0 spin in our cars using normal street tires you're 60ft is poo or you're a awsome driver.

Personally, like a said before. 10 to 11ish PSI 480whp/450wtq is perfect for the street.

I think everyone has agreed that first spins all day as far as my comment was to the fact someone said if I was full throttle I would spin 1st through 3rd and I said that's not true....I never said anything about 1st I said u can hook in second...so I guess your quote to me is irrelevant no offense.

OK, let me clearify. You can do a roll of 30mph in 2nd gear and reach 170mph with 0 spinning. Correct?

Cause all my comments we're about dead stop 60 ft.

From what you're telling me you can go full throttle at a 30mph roll with 550 to 600whp and have 0 issues with traction.

tbh at 8 psi G37 that wieghts 800 more pounds(me). I'm still blowing the wheels off in most of 2nd.

To answer my question with a question.

What tires are you running, rear end ratio, and suspension? No where i'm calling you a lier just like know how to improve my own traction.

1.yes
2.i was reply when someone said to me I would spin my tires 1st thru 3rd...I think this is a miss understanding between us..
3. I have 500 whp on base tune not sure 13psi.
4. Tire= whatever is stock on 2014 ray..I think it help there is around 3k miles
everything else was stock...I mite get in trouble but ill post a video of 2 pulls against a 500 whp cobalt. ..
now I have be coilovers with 12k front 10k rear and it's even better I think
