Need Tune & Strong Rear

**Numba1TA** · 11-18-2008, 04:34 PM

I just got K&N Fuel Injected Air Intake, Hooker LT headers, QTP off road cataylitic y-pipe, and GMMG chambered exhaust put on my WS6 and was wondering how much a tune will cost and what type of tune is the best. Also what other mods would be good with this setup and how can I make the rear end stronger? thanks

I got quoted for a good tune (on the computer ...takes a while hours) and dynotime $500

That 10 bolt will eventually blow no matter how you try to make it stronger.

Around $500 seems close to what it would cost for a good tune, I got mine on the east coast and I think I payed around $400 or so.

Are you an auto or M6?

I'm an A4 and was thinking about doing 3.73 gears and some kind of girdle

**chieftransam** · 11-19-2008, 08:38 PM

Well that 10 bolt should last a little longer (since your an A4) than say someone with a m6.

You can do the girdle but I'm honestly not sure how much stronger it will make it. I never messed with the girdle. After I busted my r&p I just upgraded to a 12 bolt, now I have no worries! I'm sure there are people that know a few ways to make that 10 bolt a little stronger, just not me.

Since you're A4 like me I recommend Moser 12 bolt rear with either 3.73's or 4.10's. The 10 bolt stockie can last depending on how hard you run the car, but I would definitely recommend the 12 bolt if it is strictly for racing.

Ok sounds good and what gears do you have and at what RPM would I be reving at with 4.10's while driving on the highway. Im trying to keep the car streetable but still perform at the track. would like to find myself somewhere in the 11's. Whats your opinion on cams?

Is the Moser 12 bolt good or is their better and does GM make 9" rear ends or is that just Ford? How much hp gain did you see with your small cam setup.

I still have the stock 10 bolt with 2.73 gears, which is the norm for a baseline TA. I don't know what you would be reving at with 4.10's, sorry, maybe someone with 4.10's could answer that for you. If you want it street and or track then generally people opt. for 3.73's. But some other people use 4.10's for street / track too. Depends on preference / set-up.

As for cams, you could go with something small or mild and get into 11's.

I have the Midwest Chassis 9" rearend with 4.10's. In 6th gear doing 65 or 70, I'm taching around 2200....2300rpm. When I still had my '98 with 3.73's I was taching around 1800 to 1900rpm. One thing is for sure, with the 4.10's, it raps out a whole lot quicker....I find myself hitting the rev limiter faster. Much different from the factory 3.42's that were in it eons ago!! I really don't think it's much of a sacrifice revving 500 more rpms on gas mileage compared to the quickness you gain in the process!!!

Thanx for the advice so i guess I should go with the 4.10s and it will still be streetable. I was hoping the RPM's would stay somewere in the low 2000 range on the highway.

**herculesrider1** · 11-23-2008, 12:25 PM

Please allow me to correct myself.....in 6th gear with 4.10's, I'm taching 1800 to 1900 rpm doing 65 to 70mph. Sorry, I mostly travel these backroads of Tennessee and rarely get out on the highway, I broke the law today on the way to church to get the actual rpm's at that specific speed...God forgive me!

Always have fun on cruises around here. Always a race or two.
