I just ordered my exhaust, now waiting for the heads, what do you think so far?

Re: I just ordered my exhaust, now waiting for the heads, what do you think so far?

even so, 3.73s wouldn't be a wise choice...as stated before, fuel economy can't be his goal with a cam and PnP heads/intake. 4.11s or 4.56s really should be his goal

4.56's is too much gear IMO unless he doesnt plan on driving the car on the highway ever. 3.73's will go great with the heads/cam and not totally kill his gas milage. i woulndt tell him to go bigger than 4.10's. unless the car isnt his DD.

Re: I just ordered my exhaust, now waiting for the heads, what do you think so far?

and how many people do you know that DD a cammed car with PnP heads and intake?
Also, the term "gas mileage" has two definitions: city mileage and highway mileage. True, tall gears harm highway MPG, but also typically increase city MPG by the same difference because the engine does not have to work as hard getting up to speed and doesn't have to recover from bogging down in low RPMs. So, if his daily commute is 40 minutes of pure city, high stop-and-go driving everyday, then the taller, the better.

i completely understand how gears work, but he never told us weather or not it was his DD.so im assuming it is. heads/cam car can behave fine as DD's if you get a cam that's properly sized. and with 4.56's first gear must be all but gone, stock it only goes to around 25.

EDIT: sorry for getting this off track, im done, sorry.

Re: I just ordered my exhaust, now waiting for the heads, what do you think so far?

well stock my first gear goes a slight bit beyond 35... I may go 4.10 but 3.73 seems a bit more promising in terms of highway mileage and quarter mile times. I am 100% sure my car only has 3.23 stock, I wish I had the 3.42s but only automatics came with such gearing. Mostly I am worried about injector size for higher-rpm use and that GT2 cam

Why more promising in the terms of 1/4 times? the current Cam-only record holding V6 has 4.10s. Wether or not your injectors will keep up with the new additions..that depends on the DA in your area, which greatly effects how much power you make

Re: I just ordered my exhaust, now waiting for the heads, what do you think so far?

True... Im not looking to set records on this setup, hopefully mid-low 13s but if I am able to do so then by all means I will lol... No 4.10s or 4.56s until I get my Gforce transmission, that 2.94 first gear will be a bit longer than my stock 3.27 first gear so in that case I'll probably get some 4.10s or 4.56s...

I figure if I'm doing 14s as I am right now, basically stock light mods and weight reduction, I should be able to crack 13s easily and get deep into the 13s with some work.

Happy new year to all by the way, I missed the ball dropping while I was jumpstarting my car lol :(

with 3.42's in a basicly stock M5 would force you to shift into 4th in the 1/4 mile, killing your times.with 3.73's your'll probally be around 2300-2400RPM im 5th gear at 65-70mph.

If you're talking about mid-low 13s, you are on the verge of breaking records. The Cam-only record is 13.61, just to give you an idea of how...ambitious your goals are. For comparison, WickedSix9838's car has head work, cam, longtubes, a fast shifting tranny, DR's and 3.73s, and hit 13.3. The last 4 items on that list you either don't have or didn't mention getting, so mid-low 13's is gonna be mighty difficult...remember, the faster you go, the more power you're gonna need to take time off your ET. It's exponentially harder going from 14.9 to mid-13's or lower, as compared to going from mid-15s to 14.9

You guys missed something important, if you want any of this power to the ground you need an Aluminum DS, instead of your crappy 2 piece.

and an AL flywheel too, theres alot of stuff he can do that wont effect gas milage.

Re: I just ordered my exhaust, now waiting for the heads, what do you think so far?

I've got the aluminum flywheel already, that made a world of difference in my opinion. Aluminum driveshaft is up there on my list of things to do, most likely that'll be once I get the new engine in the car. Underdrive pulleys should suit me well too, as may removing the bung for the EGR on my pacesetter headers (I notice it pertrudes a good amount into the primary it's located on).

Also, I've taken some things apart on a blown up 3800 series II given to me to see how things work, and I'm thinking about polishing around where the water pump bolts up to reduce turbulence, along with having the intakes ported and polished to perfectly match the intake ports on the heads, to reduce air turbulence going into the motor. Maybe a waste of time but hey every little bit counts right?

The cam-only record of 13.61 is on stock heads right? I do have some fully worked ported and polished heads going on the setup with the intake manifolds as well, minor weight reduction and a manual transmission which is slightly more efficient than an automatic to my knowledge. Does anyone know the weight of WickedSix98's car? I know my car comes out to be a hair under 3400 pounds with me in it, me weighing in at 160 bot counting all the junk that was in my car at the track, that puts the car at 3240 pounds roughly.

Re: I just ordered my exhaust, now waiting for the heads, what do you think so far?

Here's to avoiding confusion, I don't know how to do a sig here I'm a newb to posting lol although I've been reading the forums for nearly two years... Well heres what Ive got compiled up as far as what I'd like to do to hit low 13s.

Currently: 97 Camaro Y87 w/ LSD 3.23 gears, K&N Filter, 205/70R15 all seasons on steelies for winter, alum. flywheel, stage3 clutch, flowmaster w/ highflow cat, bigger oil filter free mod, de-screened MAF for the hell of it, deleted EGR since it rusted off. Best ET 14.9@93 in high humidity and ****tty track conditions from the mist.

Plans: Pullies, stage3 clutch, flywheel, driveshaft, coldair intake, full 3" back exhaust w/ headers, summit turbo single out muffler, GT2 cam, p&p heads w/ valves etc, springs, roller rockers (probably going with 1.6 due to big cam), lighter stronger pushrods, lifters, intake manifolds matched to heads, 28-36# injectors, thinner head gaskets, fuel pump, MSD ignition system, suspension, small misc mods like bigger oil filter for less drag on oil pump, 255/50r16 tires, 3.73 gears (or 4.10s when Iget the gforce T5), new style brakes w/ dual piston calipers, battery relocation, and whatever else i forgot to mention

Re: I just ordered my exhaust, now waiting for the heads, what do you think so far?

You said you descreened your MAF, does it cut out any at idle or even die sometimes? Or does it still run fine?

I like your list of future mods, it sounds good and it might just be enough to get you close to where you want to go. Good luck with it. Honestly, you have all the necessary equipment to do it, it's the tuning that is going to be the most crucial part of this project, IMHO. So, if you are doing the tuning yourself with HPTuners then read up on all of it (and it's a lot to read) and try to get the most you can out of it. If you feel that you haven't gotten all of it from the tune, then go get it dynotuned (or find a professional to come help you with the HP Tuners).

Good luck man, sounds like a fun project.

Looks like you're prepared to spend a ton of money..some of it unnecessarily. Our pullies are already essentially underdrive, the stock coil packs have been proven to be nearly as sufficient for 3.8 applications. I would hardly call tires and gear "small misc mods"; your low-13's are just a fantasy without the right tires and gear. Also, a lightweight battery would be a better option than battery relocation...to move the battery to the back, you'd need a long length of battery wire, which is heavy and expensive. The only real reason you'd need to move the battery to the back is if you had an FI setup that needed the space up front.
