mid to low 11's???

[4doorvette]

hey guys im a new member but i been on this forum for alittle over a month now so i know that ponitac g8=charger r/t slayer:boxing:.
my plan for when i get my g8 is arh header system + otr cai + non dod cam 228/240 + vector 93 tune + 3200 tc + 3.27 pumkin. if you do the math it sounds right to me that this g8 will be dipping into the 11's and if im right that means pontiac g8=lambo slayer:boxing: lol

[GRRRR8]

Yes it will! I am shooting at 11.30-11.50 on ET Streets with a 3600 stall.

[13 QTR]

I hope to be there without the stall. Hoping for high 11's by just adding some headers.....and some slicks....

You are gonna need more then that. Others have tried. Slicks and headers MIGHT get you a 12.40.

So slicks won't take off atleast a .5 sec??? With my 12.7 on streets....I was just leaving off idle.

With my srt....I went from 13.3(street tires) to a 11.8(m&h slicks)

I've seen gto's go 13.0/13.1 to a 12.3/12.4 by changing to slicks...
damn't.....I need alot more money.....

[Darkside]

What were your 60' times?

You may get a full .5-.6 with a 3600 stall and slicks. The SRT was a manual so you could launch at hi rpms just like the GTO is. G8 is maybe 1800 rpms on a max launch with stock converter.

[13 QTR]

What were your 60' times?

1.91-1.92 6 passes in a row....

[99-LS1-SS]

I also believe the SRT4 was much more traction challenged than your G8.

[wreckwriter]

Don't forget 13 QTR has the 3.27 diff.....

[GRRRR8]

1.91-1.92 6 passes in a row....

Your 60 is better then most. I would think stall and slicks and then headers or do it all at once! :woohoo:

[13 QTR]

Seeing how I only get to the track about 2 times a year...I can't see getting slicks till the other mods.
My next is the headers....SLP....cause I already got a custom cat back...h-pipe,with no center thing or no bullets,out to magnaflow mufflers.
Later...I want the dod cam from new era,then turn off afm.
I know .....why do dod cam and turn off afm?? cost....
Plus..I got 2 ecms.....I'll have 1 with,and 1 without...if I get mileage concerns...
If the dod lifters conk out...I'll have them replaced under warranty....the tech won't say anything about the 'other' stuff...

[13 QTR]

you ain't kidding...

Hell I had higher trap speeds on street tires....I'd blow thru 3rd and run 13.3@121. Put on the slicks and average 12.0@ 116

[4doorvette]

if you dont plan on going over 140 mph isn't it smarter to go lower on the gears like 3.45

[GeorgeInNePa]

I would equate your gears with my converter. I already have headers.

With both gears and a converter, I could see 12.1X or 12.0X if you got the right amount of traction and had low DA.

I went 12.560 and I know it will go into the .40s or a touch better when I get some more seat time with DRs.

The thing to remember is that the DoD system is limiting your redline. Your Shifts could be higher to help keep your RPM in the "meat" of the power range.

[Mike@NewEra]

Why is the Dod system limiting the redline? Because of camshaft profile limitations? Just curious what you are implying.

[99-LS1-SS]

I didn't think the DOD lifters could handle high rpms. Is that not the case?

The DoD lifters in my car make a lot of noise with the rev limiter set to 6400 and shifts at 6200.

I wouldn't trust them at 6500 and 6700.

Sorry, I just don't have faith in them.

[Ed Curtis]

I'm sure there are those who try to use the wrong pieces (re: cheap shit) and are going to have out of control valvetrain. It even happens in the non-DOD engines. Haven't seen that in your DOD combination, have you Mike...

[Mike@NewEra]

Oh. Since I did the High lift DOD cam, I have probably 70+ passes at the track, 60+ pulls on the dyno testing things, and I bring it to about 6700 rpms crossing the traps at the track in 3rd gear everytime. I have my engine apart right now checking everything, and doing some very light head work, the lifters look perfect, as do the lifter bores. I will try and get some pics up if I get time if you guys would be intertested.
I am not saying you are right, or wrong, just simply saying that I have done a lot of testing, and it has held up for 9000 miles without missing a beat, sure, the DOD lifters are noisier though, but in many cases when a camswap is done there is some additional valvetrain noise to come along with it without DOD as well.

[GeorgeInNePa]

Hmmmm, well that is some solid, real world data.

Thanks.

Pics would be great.

BTW, what is your rev-limiter set at?

[Mike@NewEra]

7100 rpms.

[99-LS1-SS]

7100 rpms.

That's screaming. I bet that thing sounds sweet turning that fast.

[wreckwriter]

Yea but the power band ends way before that.

[Mike@NewEra]

I will try to get pics up, as you can see with the last 2 products we have developed and released for the G8, I am by no means a good photographer and I am limited by my camera as well.

[Mike@NewEra]

I only rev it to 6700 in third to cross the traps in 3rd gear without having the occurance of another shift which would slow down my time. My shift points are set between 6300 and 6400 depending on which gear it is in. I don't bring the rpms up to 7100, just keep the limiter there so I don't hit it. I actually cross around 6500, but stay on for a split second after I cross the traps.

I went back and checked my logs and I was off by a couple hundred rpms of where I cross the traps, so I edited my posts.

[GeorgeInNePa]

What is your normal shift point?

[Mike@NewEra]

6300 in first, 6400 in 2nd, then I rev out 3rd til I cross. This year will be a little bit different though with the new OTR intake and milling the heads with a valve job etc. Hoping for a few tenths off my time and a few more mph. And, maybe some N2O, but I haven't decided if I want to do that or not yet. If I spray it, I will be revving out 4th til I cross.

[13 QTR]

^ that answers some of my questions. I really don't want to rev over 6500...maybe shift at 6200. With these gears...it'll get there quick. I was actually looking at the low lift....but now,maybe the high.

For New Era....if I do your dod cam...I want to keep the cost down...so,would the stock rockers be alright? I don't track it much...just run the hell out of it on the street.

[Mike@NewEra]

I highly reccomend the use of the Yella Terra rockers with our DOD specific camshafts, there is a better swipe pattern across the tip of the valve with them, and they quiet down the valvetrain a bit too.

hey mike what is the avg hp gain from using yella terra rockers on the 228/240 non-dod and the dod high lift. thanks

[Mike@NewEra]

It is minimal, 3-5 hp. It is just a better quality product than stock, and will outlast the stock rockers by leaps and bounds.

[4doorvette]

any opinions?? if 3.45 gears make you faster without much top speed loss compared to 3.27's why aren't they the most popular choice

[Mike@NewEra]

With the stock gear and a 28 inch drag radial, you can cross in 3rd gear and not waste time on another shift if you are making around 400-425 rwhp. With the 3.27 gears, you will have to shift into 4th gear just before you cross the traps either way. But, if you are sticking with the stock stall torque convertor, gears will definitley help you out.

What DR are you using now, Mike?

[Mike@NewEra]

M&H 275/50/17 on an fbody 17 inch wheel at the track. I drive around on the stockers.

I bought a set of Fbody 17x9" rims, like you suggested. ;)


Do you find these hook better than the ET Streets? Or are you just looking for the height/circumference?

your talking about drag racing i was refering to 3.45's being better for street racing

[GRRRR8]

A 3.45 for the street might be too much with 26in tall tires and a stock motor. If you were shifting at 6500+ I would say that might be a good choice with a 26.5-27in tall tire.

3.45 in a car with 275/35/20 rear wheels, 228/240 non dod cam, 3200 yank, nep otr,vms 93 tune, vms tcm, arh catless headers. i think its just right. my opinion:)

If you do all the mods in your first post, it won't really matter, on the street.

Traction will be hard to come by, whether you do 3.27s or 3.45s.

so theres no way of getting this car to hook up without drag radials. how bout more torque mangement in the tune.

[Mike@NewEra]

You don't want that, it's not fun not being able to control the power, not to mention, that is getting pretty difficult on many levels.

[GeorgeInNePa]

I have the stock cam and the stock gears with an aftermarket TC.

On street tires, if I just stand on the gas, there is no traction until 3rd gear.

[Panther 2]

My car blows the street tire off without an aftermarket TC , no slicks no 11's
