its possable, I find it somewhat hard to believe

Then again, my car runnin like a 6.3 to a 6.8 0-60 I find hard to believe also. Do you have any tracks within 200 miles? 3 grand...I think you can spare 20 or so for a few runs to know your times

anyway....enlighten us on your cars times, and what not, redneck called you out. Youve got enough creadabality (sp) here to where I wont say your lying, just currious is all.

[DemonZX]

Keep in mind Redneck he did say the S-charger was tweeked. So he's probably got more boost...+...other performance mods. Given human error on the stop watch I would say he's around high 5's. Like a 5.8-5.9 to 60. That's my take on it.

[-The Stig-]

Very true Demon, but even with all his mods he's still only pruducing X amount of power... which is why I brought this up. He still weighs more, has less power over all than a stock Z28 of his year.. yet kills it performance wise?

And human error could be a large factor, reason magazines dont use stop watches any more in testing. Its all done at the track.

At no time do I think Student is lying, I respect his opinion on AF. Just I think the circumstances are hard to believe. But by all means prove me wrong.

[student_anonymous]

Redneck, i'm glad you brought that up. I suppose i was so pumped at the numbers i didn't take into account the fact that there are reality checks to made considering the mathematics of the car.

I went down to a track to have the car actually tested...i don't want to look like a dumbass on here for having numbers that are inaccurate due to human error on the stop watch! (nice going Shawn, )

Unfortunately i couldn't do a 1/4 mile run as they don't open that up for anyone until the evenings, but they did set me up on a 0-60 straight away. What they did was they had a laser-timing system set up every x number of feet to record your speed and time, and so i went from a stand still up to 110 km/h (100km/h is 60mph) and then shut it down.

I pulled off 5.979 seconds as my best time, the worst time was 6.351. Way slower then what i wanted. I think part of it is my tires, the other part is the fwd, the rest of it is in the automatic transmission. I now have true numbers to work with here, and i'm gonna guestimate that this time makes the 1/4 mile about 14.2 to 14.7 seconds...will have to try it out again once the headers are done.

So yes, i'll be getting some headers on the car, so i can shave off some time on that 0-60, but i have no idea what kind would work well...any suggestions?

[-The Stig-]

Human error.... It happens.

5.9 isnt too shabby at all. Keep it up.

[DemonZX]

What is the engine model? year? I'll make a few calls & check some stuff out for you.

[-The Stig-]

Should be a Superchaged Series II 3800 V6 out of a 94 Bonniville SSEi.

But could be different...

[Cbass]

My numbers came from Car & Driver... I remember noting at the time how 5.9 seconds was quite impressive for a heavy FWD sedan.

[dbartoschek]

Redneck, you said:

Actually, they cant...

95 Bonneville SE 0-60: 7.1 1/4 15.4
96 Bonneville SE 0-60: 7.3 1/4 15.8
98 Bonneville SE 0-60: 7.1 1/4 15.5

The SE models are still supercharged, but also only weigh 3442lbs. 245lbs lighter than the SSEi model... yet still cant break below 7.0.

running a 0-60 time of 5.9 would equal about a 14.3-14.5 1/4 time...ehhhh I dont think so..

and a 0-60 of 5.4 is like a 13.8 to 13.9 run... again I doubt it.

My proof... so you dont think I'm pulling these numbers out of my ass.
1/4 mile Times By stock Vehicles
Technical data


You are stating SE model 0-60 times....SE's had only 170. or 205hp i believe and were not supercharged....SSEi's were the only trim you could get the SC'ed engine in.

[-The Stig-]

Umm Yes you could.

You could get a Bonneville SE w/ Supecharged V6s

Proof

I'll highlight a section of the Article for the lazy people who dont like to read.

"The Bonneville benefits from a powerful base engine; a Series II 3.8-liter V6 that pumps out 205 horsepower and gets an amazing 30 miles per gallon on the highway.. New for 1996 is an optional 240-horsepower supercharged variant of the base V6, which replaces the old 225-horsepower supercharged 3.8-liter previously available. And, if you must have the supercharged engine but don't want all the goofy aero add-ons and tacky gold trim that come standard on the SSEi, you can get the blown motor in the base model. One stipulation exists, though; you've got to order the SLE package, which gives you some of the goodies that come with the SSE."

I do my homework.

this was asked a while ago... butt a s/c and turbo'ed car is definitely possible.. the only thing is that you can't run high boost on either forced induction device and that you'll have cooling headaches... you're gonna have to run twice the amount of intercoolers... and by the way... is your bonne intercooled(i'm too lazy to look).

Can headers really put out 20-30 more hp, seems a bit optimistic to me.... but what do i know?

[Cbass]

Well, considering his other upgrades, the headers will probably be the restriction right now. That and the stock cylinder heads... Hey student, did they do any porting work at the shop? That would also make a really big difference.

[DemonZX]

Stillen headers put put 20+ or close to it for the Z. You have to think how restrictive the OE manifold is. Compared to the wider and more efficiant headers.

All i was stating was that your times were from SE model Bonnevilles, which the majority of which did not have the SC'ed engine....most likely those weren't SC Bonnies

[fatninja19]

Also, you'll see gains from highflow cat's... oh wait.. do you have those already??
