You, like, completely missed my point. I even said In case you didn't understand again, I'm saying you'd need a much bigger turbo to notice an appreciable difference in spool time and that a 16 and 18G are probably going to spool about the same time give or take a few hundred RPM.

Besides, my whole diatribe about integrals (the area under the curve... not "internals," the things you swap out under the head) was to answer RydnLow97.

 

LOL

Did you even bother to look at the numbers? It's pretty obvious that it's not that easy to get into 13's with the stage 0. If it was, ZPI would guarantee everyone to hit 13's with their stage 0 kit. I'm not saying 13's can't be done but you make it sound like it's supposed to just hit 13's even with slicks. Slick wheels and tires cost money and that's just one of the things you need to have. Even if you manage to hit 13.99999 with slicks that doesn't mean you have a consistent 13 second street car.

 

all I am saying is.... if the car weighs 3000lbs and the car makes 230whp then with a good driver it should be in the 13s . that guy mike from NJ ran 14.9s on N/A with no special mods . ur tellin me with an extra 80whp 1 second in that range isnt possible ?

^^^^ but I dont think u understand , 12psi from the 16g and 12psi from the 18g or the gt35r CFM is how u make hp not nessecarily psi . so actually there is a difference between the 16g and the 18g . and at lower boost level the 16g may actually make more cfm . ya dig ?

 

I concur. My 350Z out of only 3 runs I was able to get at the stip (first time taking it by the way), I clicked a 14.1 @ 99 or so. The 350Z weighs more and puts out roughly 230-240whp and 230wtq. A tC with 230whp with a driver who knows how to drive it should trap at MINIMAL 100mph and net a High 13sec, given he has the means to traction.

By the way, the 350Z was bone stock, as if it came off the dealer lot, except I had crappier tires from doing to many side tail action when making turns... I think I can pull a high 13 with good grip in the Not so drag friendly 350Z.

 

You can't guarantee a drag ET. That's rather obsurd to think everyone can hit a 13. That doesn't make it LAW that it can't be done.




That is until you do it again, and again, and again. Give me a 230whp tC, I wouldn't leave the drag stip till I could put 13 time slips on it.

 

this is a perfect example rhythm ran 14.1 @ 99 in his 350z , I run 13.6 @ 99 im my s/c toyota tacoma making around 240whp with 3250 lbs . ill bet if he ran the car a few more times on the track he would prolly be running 13.80s @ 101-102 easy .

 

If he ran all night, my assumption is extereme heat soak... no intercooler. It would be challenging. 14s are doable no question, but until a Stage 0 breaks 13s... I will leave it at that. :D

 

Are you guys aware that after 3-4 runs at WOT, your car goes slower throughout the day? 14.1 seems like the average quarter mile time but does the 350z have the same gear ratio as a TC? Does the TC come with an LSD? RWD vs FWD drag theory? Does the 350z have turbo lag? Better 2' times with better clutch?

350z is rated 245whp (3100lbs curb weight)
Stage 0 is rated 230whp (2900lbs curb weight)
Edit: + weight of the turbo setup

200lbs difference pretty much compensates the 15 extra wheel Hp

I'm pretty sure the TC is not known for launching off the line. That's where you can find the difference between a 350z and Scion TC.

Like I said, I'm not saying it can't be done but it definitely won't be cake walk. You're gonna have to raise the boost and get better fuel delivery to stay consistent at high 13's.

 

^ Good point. Apples to Oranges comparing a FWD car to RWD (Taco,350z)...

FWD isnt the easiest to run at the track.

 

you guys crack me up .

 

Traction in a open diff FWD is limited. Otherwise ZPI would be in low 11s now...correct me if Im wrong.

 

You obviously don't know what a Boosted tC looks like next to a 350Z...

RWD owns coming off the line, and probably up till the 1/8th mile mark. 1/4 mile, we are talking a substantial difference. Let's put another power mod in the mix, and take for instance a TRD S/C tC. Some of the consistent records or perhaps the best so far down the 1320 has been a 14.3 on a fairly baisc modded S/C. A Stage 0 is faster than a basic modded S/C tC. Like I said, 13's (albeit maybe a 13.9/13. can be had. And ToyotaRacer is right, I would have been clicking 13.8's all night if I could have had a few more runs, as that 14.1 wasn't even on a hard launch. I feathered it when I could have dumped it. Traction was hella Good that night.

 

Splendid. Now we're talking about different things. Don't even consider the GT35 anymore; that was used as an academic example to show that having more power sooner doesn't necessarily mean beating a crapload more power much later. I started that discussion to help consider turbo choices not to specifically discuss the advantages or disadvantages of any single turbo.

Just look at what I said with the 16G and 18G and 20G.

I said that the difference in spool isn't going to be aggravatingly noticeable.

I did not say anything about an 18G beating out a 16G or vice versa.

Do you disagree that the difference in spool time between a 16G and an 18G are going to be little?

If you don't disagree, then we're in accordance!


edit: btw, I just realized this side "debate" is more than aa little offtopic...

I would need to see the compressor map and know the lb/min on the 18g . to know weather or not I agree .

 

Well the 16g ZPI uses is a knock off but has been casted differently to reflect the porting of a ported Evo III 16g. So there is really no accurate compressor map for the 16g ZPI uses.
