Bolt-ons = more HP, What about measurable acceleration improvements?

Yeah, half a second is huge.

Rough math here but if you pass the finish line at a constant 105 mph you will have traveled 77 feet from the line in half a second, which is roughly the length of 5.5 370Zs positioned nose-to-tail.

yup lost to a 350 with the celi by like 3 sec and it seemed like he was 30 cars away lol

Dude... that's nothing. I ran my then stock Mustang GT against an IHRA "top fuel" style dragster at a T&T. My 13.9 @ 100 was nothing for his 6.xx @ 200 mph test run.

Can't believe they let me do that but I will never forget it. So awesome.

Well. Maybe I'll just do that...

Good! Your *** is going to appreciate it.

travisjb · 06-19-2009, 12:45 AM

there are four areas i've been initially focused on with mine... power, weight, suspension, and more efficient shifting

As for track performance, the most bang for my buck has been in suspension... general rule is tires make the biggest difference, followed by reduced unsrpung weight, then stiffer suspension with flatter cornering (sway bars)... I think I've gotten more time off my track times from suspension work than power/weight... still on stock tires, so it only gets better

Re power and weight... first, 0.5 secs off 0 to 60 is a pretty big deal IMO! I suspect that is about where my car is at... if in addition to adding that much power, you can pull some weight off the car, the difference is unmistakable... I have no problem keeping up with and passing new M3s on the track... I even got by a GTR a couple track days ago... once I have another 200-300 lbs and hopefully another +10-15 hps, this car is going to rip!

I appreciate your skepticism, but I think the gains we've all been making are worth the investment and paying off in real performance

I'm not a track guy, but that is impressive if you are passing M3s. Partly the skill of the driver, no?

I can certainly see that with the bolt on intake and full exhaust that the Z could likely match or slightly beat an M3 in 0-60. Some mags quote the new M3 at 4.3 seconds for 0-60.

not trying to brag, just picking a benchmark that we can all relate to... a little investment, and this car wins

AB370Z · 06-19-2009, 01:40 AM

No worries...some of us will only be daily drivers, but will live vicariously through others like you who will do our cars proud on the track!

spearfish25 · 06-19-2009, 05:06 AM

I'm glad to hear that you guys feel the bolt-ons make a difference. The short of it is that I want to do them. I just can't afford it right now. Perhaps I was just looking to rationalize not doing them so I don't wreck my marriage telling lies and spending cash on car mods that my wife will never understand.

Still, the HFCs may just be coming in the next week or two...now I have to figure out how to piece together that ridiculous ratchet aseembly to break those sticky bolts loose...

Travis, as for passing the M3s...that's great. Did you notice an interval improvement in passing those guys with the bolt-ons, or did your driving improve? I think we underestimate the power of a skilled driver at times. When I did the hotlap in a stock 370Z with a pro race driver, he was smoking cars that I was struggling with. Hell, he could hang with some 500hp vettes that were just zipping past people earlier. Likely just a combination of both a faster car and better driving for you though.

Come on! Isn't there a company in Chicago that wants to test their bolt-ons and use my car as the guinea pig???

travisjb · 06-19-2009, 10:42 AM

not going to tell you what to do, but I'm a big believer in spending within your budget... nothing wrong with waiting a while

I have 4-5 years of track experience, and I learn something every time I visit the track... so yes it is possible I am improving my times some... but we're talking tenths, not seconds

Here's a nice clean one that isn't in the database (which I shall remedy shortly). This vid is a 2-part vid to show the sound of Berk's prototype CBE (still under development). Part 1 is just the Berk HFCs with the stock exhaust. Part 2 adds the prototype CBE.

Just purchased the Berk Test Pipes and a BM short throw shifter. I have to wait for my car to arive from Hawaii to pick it up (July 7 about) but you best believe im going to be in the shop as soon as possible to add both of them. With out a doubt im sure both of the upgrades I am add are going to make a difference. You should definitely do the HFC or test pipe depending on your local laws..
