2003 Infiniti M45 gtech pro o-60 quartermile times

[viperatc1]

my nephew has a honda s2000 and he ran a best of 13.7 at atco raceway last year. i think that's pretty impressive for a stock car. he let me borrow his gtech pro with my m45 and i was verry happy with the results.my first time out with the vcd on was o-60 6.3 and quartermile 14.5@99. second time around vcd off was 0-60 5.7. i didn't do the quartermile because to much traffic.the next morning i found a good spot and i was able to get good traction with vcd off and my results were 0-60 5.67 and quartermile in [email protected]! i didn't sleep that night thinking about how powerfull this 3851 pound car is.just thought some of u m45 owners would like to no some info.

It's threads like this that make me want an 03-04 M45 as my next car, then I think about the fact that I have no need for 4 doors. hmmmmm

[viperatc1]

i also got some horsepower #s no torque though. 2 tries first shot read 278 to the wheels which by the way was very happy with that and last shot of the night it read 290 to the wheels!now the weight i put in was 4200 pounds which might be a little high considering i had a little less than a quarter tank of fuel. i saw alot of previous post that this car has not been over a hundred in the quartermile but if this gtech pro is anywhere near as acurate as they say than this car is easily a 100mph+ quartermile car.will post true quartermile times in a few months from etown raceway when they open!!!

[viperatc1]

by the way the quartermile results were very difficult because of the amount of torque this car has. a good launch at the track should bring this car in the high 13 sec range with no problem at all. my wife owns a 2003 infinity g35 coupe auto which is capable of a low 14sec quartermile time at about 98mph and the m45 will blow it away for sure!

This is good stuff. Cant wait 1/4m. numbers.Does your car have any mods.?Try couple more times to see what eles car will come up with.thanks, for the good news.caug.

the car is bone stock down to the air filter

[viperatc1]

the car is bone stock down to the air filter . temp thatday was about 45 degrees

[caug1]

do you use mobil one full sintetic oil?

[viperatc1]

there was one guy on the infinty-driver website that tested his car new in 03 and said his best with the gtech 0-60 was 5.2 sec! he is the reason why i am testing my car now.his temp that day was 65 deg which would acount for more traction.it makes perfect sense!so at the track i should do well! i'm very excited to see the results but i am very confident in the m45 because i have really been blowing away cars bad!from a roll on its really hard to be beat.i ran a lexus 400 from 70 to about 130 and he got the jump but i still passed him at about 110! and also an altima 3.5 was no contest!he wasa so pissed that he drove behind me with his high beams on till the nexy exit! soar loser. well if any of you have this first jen beast feel very lucky and proud because they are in my eyes a true winner!!

[viperatc1]

mobil

[viperatc1]

almost bought a z32 rear but i feel this car does not need it. especially with 0-60 in 5.6 and better range

[caug1]

cant wait to see funny look given to me on the highway.i had car for almost a month no racing yet.keep intouch.

[caug1]

what do you use for tires?mine came with mechelin. on wet roads when go around a corner car brakes loose a little. i thinks struts should be o.k. i got only 36000 on it.also i think new tires i will get will be falken azenis rt 615. you should read reviews on them. they are very good and cheep. they dont come in right size., but did talk to the guy from discounttiredirect.com i can you 245.40.18wider tire less sidewall bigger contact patch. he did corculation tald me speed will be of by half of the mile, becouse tire smoller by 1/4 of an inch.i say for the price and good traction it is not a big deal.you should read comants on them in discounttiredirect they are good.

bone stock down to the air filter

Good. Please keep the air filter that way too! Here at NICO, we have learned the hard way what damage the oil from K&N does to the MAF.

also i think new tires i will get will be falken azenis rt 615. you should read reviews on them. they are very good and cheep. they dont come in right size., but did talk to the guy from discounttiredirect.com i can you 245.40.18 wider tire less sidewall bigger contact patch. he did corculation tald me speed will be of by half of the mile, becouse tire smoller by 1/4 of an inch.

Since the rolling rev/mile of this tire is 803, the actual speed will be 58.7 mph at a displayed 60 mph, compared to the stock 235/45-18 tires. I do agree that this is relatively minor!

More importantly though, the minimum rim width (for this 245/40-18 tire size) is 8.0 inches because of the lower aspect ratio tire. Unfortunately, the stock 2003 M45 rim is 7.5" wide. While this is a minor difference, and the tire should fit this rim without being unsafe, keep in mind that the edges of the tire will "lift" a bit and the tread width will effectively go down a bit. So, the point of having a wide tire will be lost.

My point being that a 245/45-18 size is a better fit for this OEM rim, and unfortunately, the Azenis RT-615 is not available in that size!

Also, the Azenis RT-615 is a dated tire. It is a somewhat dated design and the material is also not up to par compared to today's tires (UTQG rating is 200 A A) and there are definitely better tires available now (albeit perhaps not as inexpensive).

If you want to stick with Falken, their FK-451 and FK-452 in a 245/45-18 will probably give you better results on a 2003/2004 M45. I do not have any personal experience with these, though ... I have only used their Ziex 512 (now called the ZE-512) and did like it on my 1995 Q45. That tire is not available in the right size for an M45, though.

If you want more info, please check out my tire spreadsheet in the Basic Spec sticky thread.

i have the mic pilot mxm4 tires on.i would say that the tires are not hooking up but you can't forget about the 333 pound feet of torque this car has!i did not by this car to dragrace but i have a 05 zx10 that i ran 9.29@145 at etown so any car that i drive is going to get pushed to the limits!and believe me most cars do feel slow to me even with power but this car really does put a huge smile on my face!gforce baby!!!!!!!!

according to many,mobil 1 is now no longer a true group 4 pao synthetic oil, now formulated with less expensive group 3 hydrocracked base-oils.

What kind of damage did the K&N oil do to the MAF??? I was just getting ready to order a K&N for my 03 M45.....I'm guessing that I shouldn't, right???

Church baby!Those numbers are killa. I wonder how my car would do with these 20's

[viperatc1]

your car is definetly hot without a doubt! hope to put some rims on soon too!

[viperatc1]

i know that the odds are against me but i'm gonna do it anyway! i was called out for a race. my m45 vs a 1993 300zx tt but guess what! i dont care about his turbo because if he doesnt launch right the race is all mine! and yes i am very confident about this. not that i think my car is faster which it very well might be but because i dont think he has the balls to beat me! well this race will be going down really soon and i will post results. wish me luck!!

Wishing you good luck! You will do well!

What kind of damage did the K&N oil do to the MAF??? I was just getting ready to order a K&N for my 03 M45.....I'm guessing that I shouldn't, right???

Basically, the oil gets into the air flow and slowly coats the MAF and degrades its sensing ability. Leads to incorrect readings and poor engine performance and, eventually, makes the MAF need serious attention over time.

We have some threads in the Online Mechanic forums that dealt with this issue in the past. The perceived gain in performance from the filter simply is not worth the risk. It is better to just change the stock air filter as often as appropriate!

Both engine and cabin and fuel filters annually.

[cremecreme]

oh crap...that was like the first thing i bought and installed when i got this car....i never thought a company like k&N would have problems...the do alot of R&D and are a very good company....so should i take it out?????i just installed about 3 weeks ago and haven't reoiled it or anything yet...guess i have to do a search????

what kind of synt.oil should i use then?thanks.

[szh]

what kind of synt.oil should i use then?

Probably any of the good synthetics will do well. The real criterion is regular changes at decently low mileages (like no more than 3750 miles ever)! Both oil and filter. As long as you are methodical about this, any synthetic or even dino oil will do well.

FWIW, I use Mobil 1 Synthetic 0W-40 and like it a lot. Wide range enough to allow use in any weather conditions in the country - with the exception (perhaps) of being in Edmonton or Calgary in the winter - and the right blend of detergents, etc.
