Intake/exhaust/reflash question

K20A2_S · 07-17-2009, 12:26 PM

^^What was you 60' time when you got your 13.4?

wstar · 07-17-2009, 01:34 PM

Good question

I never scanned the slips, and now I don't even see them in the car, I must have taken them inside somewhere, hmmm...

soaka1 · 08-31-2009, 09:19 PM

on the full stillen bolt on and tune with drags on the back. we have hit a 12.6 114

GO FOR IT!!

What were your 60ft times on that 12.6 @ 114? Great runs by the way, and your trap speeds are impressive!

You're running with the LS2 C6 Corvettes, how much power are you putting to the wheels? And what kind of drags do you have on your car? Sorry for all the questions, damn your Z is fast!

wstar · 09-01-2009, 09:51 AM

Well he's doing a lot better than similarly-equipped 370Z's (HP-wise), so I'd have to say the drag tires are the primary difference.

You should come out to the track with us Wstar I think I have TheDreamer convinced to come out

Drag racing anyone?

Sounds fun, I'll plan to be there.

Take your car and run them on a good 1/4mi track stock for stock and see what happens. The M3 is fully capable of demolishing a 370z when both are stock...but that's not to say your boss is fully capable of taking the M3 to that level

I've seen Vettes run 14's fairly regularly...and it's not the car that's the problem in those cases. Heck back in '02 I had a friend with an Integra Type R that was turbocharged and put down 340hp to the wheels. He couldn't get out of the 14's on street tires, so he thought it was a traction issue. He bought drag radials and only managed some 13.7's and one lone 13.4. I asked to drive it and clicked off a 12.7 on street tires and 12.4 on drag radials (and I'm not the best driver in the world). We got our shop driver to drive it once on street tires and he clicked off a 12.4....on street tires (we never got to see what he could do on drag radials).

Long story short...you never know. Run em and see what happens.

I really have yet to see any 1/4 mile times or comments on pulling power after putting a full intake and exhaust (minus headers) with ecu reflash on the car. From what I've read on these forums about 50 hp at the crank seems to be a fair estimate. If thats true then thats 380 hp in a car weighing around 3250 pounds vs. the m3's 414 hp and 3700 pounds. What do you all think?

The thing you have to remember is drag racing is not all about HP. The M3 has a 9000 RPM V8. Totally different machine then a 7500 RPM V6. He will have more power for a longer duration in every gear. His gear ratios are different, he has SMG (Sequential Manual Gearbox) there for will be able to shift in .08 seconds. Much faster than any human.

I hate to admit it, but the M3 is a technological marvel compared to the 370Z. Tons of F1 technology in it. Your comparing an $75,000 car to a $30,000 car (base prices). For a fair race, you'd be looking at a GT-R vs M3. The prices are much more comparable... And the GT-R clearly wins that race

mpp9 · 09-02-2009, 01:16 PM

The M3 is a technological marvel but revs to 8300 not 9k rpm. He has a stick not a smg which is the way it should be. With a reflash the Z has an 8100 rpm limit so not that far off. Again I've seen dyno readouts of stock e92 m3s and full bolton Zs and they're very similar in how the power comes on. Both lack a little power low down but have a broad torque curve up until 6500-7k rpm (the advantage to the m3) but most impressive of all they have both have an impressive hp curve up until their fuel cutoffs. On the stock Z max hp comes on around 7k vs. the modded Z making power all the way to redline. Once I have a few thousand to screw around with I think I might surprise some people. I dont' think the Z's engine is nearly as good as the bmw's stock for stock but modded Z vs. stock m3, dyno sheets dont lie. I would not place the m3 anywhere near the gt-r though, it took gm to have to supercharge one of its v8's to outdo the gt-r while the base corvette beats the m3 hands down. With a reflash and exhaust on the gt-r I've seen 600 hp on youtube videos.

Ehm... what about handling? BMW vs Nissan?

mpp9 · 09-02-2009, 04:06 PM

I'd say they're similar in overall grip. The Z might have a slight advantage in handling at the track being much lighter but still not enough to overcome the power disadvantage to the M in lap times. From my experience in the bmw, it seems much more poised when driven hard and has quicker steering input. I think most mags have the Z's lane change speed a little slower than the M's.

i think they weight approx the same.

BMW M3 weights about 1550kg withouth passenger and with full fuel tank..

mpp9 · 09-02-2009, 11:04 PM

You might be referring to the E46 m3 last gen. The new V8 m3 weighs around 3700 lbs or 1681 kg. At most the 370z weighs 3350 lbs or 1522 kg and thats being generous. I have a base model which autos.msn has at 3250 lbs (1477 kg). Its not rocket science to assume a german v8 semi-luxury passenger vehicle is going to weigh more than a 2 seater japanese sports car. The Z isn't an rx-8 or honda s2000 lightweight but it certainly has a weight advantage over a new m3.

dont want to argue but it doesnt, bmw says 3700lbs but the real weight is less.
