I had a Penton 125cc when I growing up. Loved the thing.

lol the ZL1 has a a10 in it.

Not available yet, but supposedly April of next year.

Oh, OK. The auto is faster for sure. Hey, do you know and this is an aside if the 1lE and / or the ZL1 with Ediff have the bigger 9.9" carrier aka pumpkin, aka center section? I assume so.

Yeah I did.. Only you interjected the DIY angle which was never brought up. I've been a certified mechanic for over 20 years so yeah I can put on a blower too. But to the average Joe, he or she might not have the confidence or skill set to perform major bolt ons like headers, etc. But let's take what you said. You said you could put on a blower. That would be great and it would save you around $1500... So I can assume you can put on an exhaust system given the same B mechanic skill set you say you have. A SW full exhaust system is as low $2000 and no more than $2400 front to back.. Knock off $1000 bucks for the install because you're so talented you can do it yourself and there's the nice bang for the buck you're so desperately looking for.. And as far as the tune goes, I've seen 5, 10 hp tops. What have you SEEN? So this blue car is just one example of 30+rwhp . How can you honestly believe you know it got 15 from the tune when you wasn't even there????

I'm not trolling you, but you seem to not want to read what I've written and actually respond to it, creating your own argument along the way.
I've got you saying full exhaust and then oldman saying full exhaust is a strawman because its never going to be good bang for buck, so if my answers to both lines of enquiry are getting conflated and confusing you then I apologise. Lets get back to full exhaust only then;

I very clearly said that I wouldn't tackle a full exhaust and certainly not headers on my own, I don't have the space or equipment, a centri yes, but I couldn't get the car up in the air enough for me to want to do headers and exhaust. I also wouldn't do my own tuning, so theres that, although a centri does come with its own tune, so that isn't really a concern on that front.

no cats isn't an option for me, so its not $2400 its more like $3000, plus fitting and tuning because of the above

even at $2400 self install and tuning and assuming 30hp just from the exhaust, and assuming you already have a tuning device, that's still $80 per hp

so if you are going to ignore the cost of tuning and device, E85 becomes $375 for the sensor for 30hp... or $12.50 per hp

similarly ported TB and intake is $575 for 17hp or $33 per hp and YES both give good gains across the whole curve

a centri is $6000 for 150hp or $40 per hp even adding fitting its still only something like $46



your exhaust system, even giving you every benefit of the doubt is more than double any of these other add ons

in my personal case, and yes this is subjective, even going with the droney SW system, it is much closer if not over $4000 or $133 per hp, it just doesn't make any sense to do that before doing any or all of the above

if someone wants to do a full exhaust system "just because" then that is absolutely fine, but the guy who first said its not worth it from a bang for buck point of view was spot on

[jdasnt3]

We have seen cars running very fast times at the track using stock exhausts. I too believe that exhaust modifications are expensive for the gains and most likely will not consider it as an option. I went with NPP so that I had a nice aggressive sound and a quiet sound.

I am pretty much maxed out with my performance modifications with the exception of a line lock and a converter. There aren't very good options for those two right now, but my car should be a very capable low 11 to high 10 second car without doing anything to the exhaust.

Totally agree with exhaust mods, thus why I've decided to go with QTP cutouts. At roughly $600 if you get the wireless controller making 17hp it is about $35/hp. And no tune req

Cutouts equals 17hp?

[BowtieRocket]

Thats what theyre advertising.

[BowtieRocket]

Although not the same model, here is an example of the power benefits. All subjective of course...

like to see a write up... I like the idea! I don't know how hard it is to weld in and fix the crush on the pipe. My welding sucks bad.

Gotta link to that? I don't see any claim on their web page for the aggressor model. I just noticed they have new model called the screamer with no HP claim on it also.

I think personal install cost varies and is situational. It would be better to leave it off. Even though heads and cam are clearly expensive to install.

Centri is the best but that is 150 HP and 150 torque with no warranty (same goes for any N20 claim). Parts fail at the torque level. I think if one is looking for performance for cheap and wants to drive it, a Centri, especially on a M6 is probably the most expensive mod imaginable over a 100,000 miles driving experience. Even with my projected setup FBO + heads and cam, I'm actively looking for: clutch, drive shaft, half shaft and LSD upgrade and would consider an entire Zl1 diff upgrade.


Partial bolt-ons the 6th gen are already in the 10s. I think PD at this point is merely for bragging rights at the car meet, clearly performance is limited by traction... or lack there of. So really the best bang for the dollar is a set of daily drag radials. Meaning as the Meta sits right now a A8 with FBO and DR is going to be a driver's race with anything that somebody would actually drive on a daily basis.

Car and Driver recently did a test of tires, DR, and slicks on a HellCat and the best they got was low 11s and the car was prepped and driven by competitive 1/4 mile guys.

I'm sorry but cars don't drive themselves, and at this HP level clearly it is more and more a driver's race and the best bet is on the guy with the stickiest set of tires on his "daily driver".


http://blog.caranddriver.com/whats-t...s-to-find-out/

Yeah, I already know they are scrubs and somebody's ma can put a Hellcat into the mid 10s with the same setup. I'm just saying right now A8, FBO, DR ain't losing to anything else on the street in 99.9999% of the potential street fights. Not some make believe TV show like Pinks...


Put it this way, I once said my LS1 has killed every Supra I've ever raced. Sure enough 20 emails and post come in challenging me to a race for somebody or others "daily driver" 1000 HP Supra.
1) Claim I beat every Supra I've raced, is not a claim that my car is faster than all Supras.
2) Note the claim of "daily driver" varies widely and as Hot Rod has shown in the pump gas shootouts going for more than a decade many of these streetable car (an even looser claim), can't even drive a 60 mile test loop before failure.

Yep Centri is great bang, but there are issues with that claim
1) real world performance based on the tires that are actually on the car on a daily basis
2) drivetrain issues over the log run, meaning cheap ain't cheap

Did I run DR on my LS1? yep, have I run DR on some of my other "daily drivers"? yep, do I see DR at the local car meet? yep. How many? About 1% to .1%. So what are the guys with FI doing? Simple hopping they pick on lesser cars and hopping said car does not have a set of DRs under the fenders. Oh and we are not talking 00 rated DR, more like 80 or 100 wear rated Nittos.





Just my .02.

How would cutouts add 17 hp? I have the qtp kit in my shed with the the wireless controller, just need to make time to have it installed, and i paid 482 total for my kit with wireless controller @ bowtie rocket

[bybcous]

If my total for all my parts and labor to be around 545 hp came out to about 7400, i dont feel that bad no more seeing how the supercharger would have been at least 9000 installed in my area.
