cool. i've thought about buying that cam but i doubt i will. how high compression do you have? i'm still curious what your times were n/a...

about 10-1 my best time with no nitrous was 15.3@86
i dont recomend this cam for daily drivers i have problems with the brakes cause of low vacum, and it idles horibly as u can hear it does sound bad *** though.it make sno power below 3,000rpm but it pulls like hell from there upto 7-7500

heres another of a light take off sound here

Is that duration at .050?? If so....good LORD why so big? That's HUGE for that motor... Esp without intake and some pretty major head work.... If you dont have either of those, that cam is in all actuality probably making you slower, even with the nice compression

daves12secV6

have lots of portwork/intake porting car runs mid 15's off the bottle
car has a decent amoutn of mods though im swapping in a 358ci small block this spring

Nixon1

Sounds good, definitely unique and I dont mean to second-guess you....but I still have serious doubts about that cam selection. I mean, my 302 has Performer RPM aluminum heads, and tons of mods, and Im running a 224/232 duration cam and it's walking the line for the rpm range I run it in. I can see why you make your power towards 7k though! But I seriously think you'd go faster having a lower duration cam with a broader operating band. Dont forget, a little more power all through the middle is often faster than a lot more power in a 300 rpm range right up top

well i run 4:11 gears in it so this thing screams down the track the cam is good for 7800 rpm with valve float at 8000
its basic range is 3,400-7500 rpm, and im running 3000 stall verter

Naft

i think he's going about it decently, with a smaller displacement motor you have to get it up there in the revs . . . any import making decent power makes it at like 8k, so for a 2.8 to have a powerband from 3.4-7.5 isnt that strange, he loses a lot of streetability, but with a 3k converter and 4.11s i think hes on the right track(as long as the heads are flowing).

alan has a 3.1 with 11:1 compression i think, and with all his suspension hes running just under 15, dave i think has run a 15.3 with a 2.8, so i dont think could be doing anything horribly wrong.

yeah 15.3@86 or 87 mph all motor with the 100 shot of i went 15.1@84 mph due to massive tire spin and breaking the trans mount im gonna have all march to get into the 14's then the motor comes out for the sb swap( 500+hp small block :evil grin

AM91Camaro_RS

where'd the rumors get out that i have a lot of suspension work? lol. i've heard this a couple of times recently but i haven't done any suspension work other than i boxed in the stock LCAs on the back. my stock springs and all i guess are old enough and loose enough that they work well...the car has great weight transfer for the HP level i'm at. i've pulled a 2.05 60' time on street tires without any suspension mods (before i boxed the LCAs).

Naft

Haha my bad totally, I heard it a couple times recently too, and you never said anything contrary those times, so i assumed it was true . . . your 60's are a good .2-ish lower than anyone else i can remember with a 6 though.

not minimizing your efforts either, the difference seems about equal to 1 pt of compression + .3 liters to me.

AM91Camaro_RS

yeah, that's cool its just kind of funny that that has been going around recently. and, if you want to get technical, i'm at about 10.75:1 compression, really. Once I get the motor running right again, I think I can go into the 1.9X 60' times and go a couple tenths quicker down the 1/4, too.

i need to get my time slips so i can post a few. just gota find my folder with all last years track stuff in it.heh if i dont hurt the motor this year think anyone would buy it, id sell it complete with harness ecm and chip and trans .id hate to junk the motor when i swap in the sb

Xophertony

are you running auto or stick? reason i ask is that with a stick, a lack of power on the low end might not afect you at the track at all. on the street it would only do harm in 1st gear. the t5 (for the 6s) has like.. a 1200 RPM range. if you rev up to 4K in first and shift to second you will start out at arount 2.8K.. it has small.. (i don't know what the word for a transmissions "duration" or "power band" is). i always kinda wished the thing had longer gear ratios. so it could be more usable.

but anyway, seems to me if your power is up high you shift at around 6K (into 2nd) now your at around 4.7K rev to 6K shift (into 3rd) back down at 4.7K rev to..... etc. and you stay in your engines power band that entire time.

Naft

dave i was about to offer to take the cam & top end off your hands when you put in the v8 . i wouldnt mind putting that on a 3.4 and burning my own chips for that come summer. the extra .6 liters should bring down the powerband a few 100 rpms, right?

daves12secV6

iTrader: (3)

i run a 2004r trans (auto) and with the 3k converter even at take off my rpms are already almost into my power band. think of it as letting ur clucth slip to 3000 rpms until u get moving. even if i shift early and im on the throttle enough the car never drops below say 2,700 rpms even though its a 3,000 rpm stall converter it only stalls that high if ive got it flored .naft the extra displacement would help a bit at lower rpms but the it would still react the same as on the smaller displacemnt motor

hey naft im getting a new set of heads that im going to do some wild porting on so it looks liek i may have my current heads up for sale soon.possibly my intake manifold also, im thinking about building myself a custom intake with the tpi throttle body.if ur interested stil ill sell ya the old stuff cheap



hey am91 looks liek me and u would have a nice heads up drag race any chance u could post a 1/4 time slip

Thunderfest

You have any clips of it revving, or any better clip of it running up the street? the 2nd clip is very short I can not even hear it rev other than just letting the clutch out and a slight rpm increase..

daves12secV6

iTrader: (3)

no i dont currently i only have my cell phone to take the sounds with, and it dosent do a very good job, and the car is an automatic, that second clip was the car pulling away very light throttle, thats why the converter didnt stall real high.the mic sux on my phone so i had to have it far from the car thats why its so hard to hear

AM91Camaro_RS

yeah, a race between us would be a lot of fun! I can't find any of my 1/4 mile time slips since i put my new intake manifold on the car. I have some older ones but they're like 15.3s, at best. If I can find any of my 15.0s or 14.9 slip, I'll post it.
