:bowrofl:

I still take naturally aspirated over turbo for daily driving purposes anyday. If you are seriosuly tracking then turbo if not dont waste your time. :driving:

And that is why I envy a V8 platform like the C6 Z06. Install an aggressive cam, headers, cbe, and a tune and you're easily making an extra 100+whp.

Yeah, NA mods for our cars are pretty worthless. Our engines are about maxed out peformance wise from the factory. And with really no selection of aftermarket cams we are pretty much limited to about 40whp with full bolt ons and tune.

Also if it has supporting mods the extra 40 is like night and day!

I couldn't feel any difference after I did full bolt ons and tune compared to stock. Really didn't feel any faster(louder yes!).... Now what made a huge difference was when I shed about 300lbs off the car. Then it was like night and day.

Weight helps a lot. To get the best feel per say is to reduce weight and add power all at the same time. But if done gradually you will never know.

And please don't bring this thread to where were comparing other cars. Z talk only.

your butt dyno was broke at the time lol...+1 300lbs less is a big deal, my best mod was removing 353lbs.

Also SPOHN with how irrational modding is, can't fault yourself. The average Z guy doesn't have the initial investment for a kit off the back nor the patience to wait....lol

I don't know about all of that. I really enjoy daily driving my FI Z. I don't think I'd ever refer to it as a waste of time.

You mean 300lbs after the decreases you likely saw with the bolt-on.

And I'm curious why you have to 'feel' the difference. 40hp (if we're talking to the wheels) is 15% (if I use 250hp to the wheels as stock) increase. You also shed some weight in the process.

I find it hard to believe that the combination didn't have some kind of effect. I've always heard that racing, be it drag or track, is about shaving tenths off a time...that would do it.

SPOHN I'm curious what's behind your question. Are you happy with your car with FI? I'm trying to understand why after going FI with one you didn't go right to it with the next. ...great thread by the way.

My current car is waiting to be FI. My old Z even though it was boosted (360whp single turbo) it wasn't great being those motors were not strong and you couldn't push them like now. I didn't go right into it at first cause I didn't know what direction I was headed. Then I went the track car route and was tied up with that. Then the push for power came.

I've had an 11 second street car before so I'm desensitized when it comes to quick cars. I knew going in that the Z was not going to impress in a straight line and after a little bit of thought and the OK with the wife I now have GTM's MHI paid for and hopefully on the way soon. I'm just not going to be happy unless the car does at least 115-120mph and the only way to do that is with FI.

The GT500 is just like the GT but with more power and the GT was unimpressive. Once the MHI goes on I'll put some suspension goodies on and the car should be a sexy well-rounded rocket. My wife might be getting a job soon and could be making as much as I am or more and if so I'll be looking at the 2014 Stingray about this time next year.
I just read my Autoweek about this one . Good choice.

I spent a good $5k on NA mods, got butt hurt, and went a bit overboard on my counterattack. I decided to try and reuse as much as my NA mods already installed, hence my choice of supercharger(s) kit. I could have made money back on parts, but who likes selling parts? Could have been different if My O2 sensors were extended correctly.

I'm 50/50 on Spohn's assessment. Gain 50whp for about $5-6k on just hp and cooling mods. But as noted here earlier, supporting mods for FI, and for many, install, still looking at $10k. Math still says FI is the bang for buck choice, but I've never seen an FI budget stay within budget. Mine was blown by 50%... GTM and their MHI kits... they may get people to add $3-5k in upgrades for all those kits they sold. Reminds me of a dealer selling a car for cheap to get you in their service dept and rape u there lol.

True. You can still run a TT kit on stock exhaust. But most will not. Most also already have. With GTM's kit the big a$$ oil pan (+3qt) you might not need a oil cooler if your not tracking. A boost gauge is a good bet. But other than that not much.

Since youre using the oil to cool the turbos, i would run a cooler regardless of the extra capacity in the pan. Plus a wideband, eventually a clutch, boost controller, radiator's not a bad idea... It snowballs quickly. It's still the best $/hp route to go, but it adds up in a hurry. I never considered NA mods. Sam was getting my turbo kit together when I was driving the car home from the dealer.

I figured having a external cooler works better than all that oil being self contained all the time. Wideband pretty cheap. But you are right. It does snowballs. But you either going to have it or not. Not much middle of the road with money.
