Went to Rockingham NC to run the 5.5 for the first time with the SSV4 tuned for WOT. I ran my 245/45zr18 Nitto 555's car weighed in at 3540 OUCH

The track was pretty crappy that day but as i said it was my first time at the track. Still have a lot to learn when it come to launching, Computer went dead early so i wasn't able to data log so I can adjust my shift table.

60' : 2.227
1/8 : 9.256 @ 78.38
1/4 : 14.257 @99.21

going to dyno within the next couple weeks to see where I'm at.

 

What mods you have? I am really interested in the SSV4. Is it worth it? Congrats on your first time.

 

not bad for a rookie

 

I wish I could have been there. Grad school work I tell you....

 

Good Job.....!!

Can't wait to see your next times...

 

Spacers
NWP block off
UDP
I/H/E w/ stock axle back
grounding
SSV4

More sure to come still in boxes

 

I tried really hard to convince James to run open Y-pipe. I bet he would have picked up 2-3 mph over having a cat, 2.5" midpipe and stock axleback.

 

I went from trapping 97 to 101 just by running an open y-pipe.

 

Not bad times at all... I can see a 13.9 @ 100 very soon..

 

I normally gain 2 mph from taking my exhaust off and it's just a 2.5" pipe with 2 resonators (no cat) and a dump under the car. I can see James gaining as much as you did.

 

wow... if i ever go from 100mph to 104 or suttn like that, i think ill cry i have stock cat on mines

 

Well I went from 99 to 107 with open Y-pipe + tune, so I wouldn't doubt it if you improved that much.

 

oh naw... i never run at the track from here on out unless its open y ... where is datdude20

 

nice times....cant wait to get my car out of the shop

 

Im right here....dont see u trappin a extra 4mph by runnin open y pipe...remember ajcool was runnin a stock exhaust then he ran open y pipe cuz his stock exhaust was holding him back.....u have a catback already...jus gut the stock cat and u will be aite or get a 3inch.....

i ran with intake and open headers then wit a intake and a cat back and ran the same numbers....powerband prolly changed tho

If u want to try and prove me wrong be my guesT

 

LOLLMFAO


theres manny.......never goes without a challenge

 

Dunno I'm trapping 107 with a pretty short mod list and one of them is open Y-pipe.

 

yea but when u trapped 99 u jus had a intKe right?

all im sayin is for those who have headers with a stock cat you will see gains...but if u already have a catback with a test pipe or gutted cat...there is no point of running open y...especailly of u have a 3inch catback

 

You are wrong, but you can continue to think that way. I trapped 99-100 with intake, spacers, vias delete, headers, hi flow cat, and stock catback. Added tuning and pulled the exhaust for my more recent runs.

If you think a 2.5" or 3" catback will give you the same power as an open Y-pipe, then I'll just leave you to it.

 

if u wouldve put a catback instead of a cutout with that setup u wouldve put down the samd thing.....

u was running headers and a stock catback ahich is pointless...ur not gonna see any gains from that

but if u Where to put a 3inch therd or a 2.5 exhaust u wouldve seen the same gains as a damn cut out

ur missin da effin point

 

 

So sunday it is... cause i do take u up on that offer

 

back on topic.. nice times
your car is heavy lol

 

Your argument may be true in SOME cases, but in the case of most modified cars, you will get the most power out of a completely free flowing exhaust setup (IE open headers or Y-pipe).

I have a 3" exhaust that I currently bolt onto my Y-pipe for daily driving. It has 2 3" magnaflow resonators, then dumps underneath the car before making any turns. It's about as free-flowing an exhaust as you could possibly have, but guess what... I gain 1-2 mph pulling it off and running open Y-pipe at the track. It's been proven for me on multiple occasions that I gain MPH from taking it off. Now apply that to a full catback having to run over the axle and through a muffler, and you're talking even more loss. Considering I have proof of gains and you have an argument based on your opinion, where is this going?

 

I have OBX headers, I have a modified 3" y-pipe and a cut-out right after the flex so its as free-flowing as it gets.. and I can guarantee that open exhaust > full exhaust.

Every k-series/b-series/h-seires all motor car i know runs open exhaust.

I trapped 104.6 on 275/40/17 MT ET streets thats probably equivalent to maybe a little over 26" slicks. Im anxious to see what i trap on 23" slicks.

 

your simply saying that because jp runs full exhaust and traps 108+, tell him to run open exhaust for a day and i guarantee he'll trap 110

 

No i am not..and he aint the only one....sr20den trapped 108 wit a 2.5 cattman exhaust and he makin less power than jp...

i dont even know y u mentioned his name cuz i was even talkin bout him...im talkin bout cars in general

 

My boy k series ran the same thing with an open header and a catback.......

 

"my boy" arguments are garbage. Bring your own proof.

 

Okay well i ran 14.1 with a intake and open y-pipe then ran a 14.1 with a intake and a greddy catback....both trap speeds was 100mph

next question

 

Im sure there are a few dynoes in the dyno section that could end this debate. I think streetzlegend did a comparison with his car but I cant remember if he had an aftermarket catback or not.

 

Yup he gained 7 hp over his aftermarket catback with his cutout open.

96Sleeper did it also with his S/C 3.5 and gained 20hp with it open

wow what a surprise, who would have thought less restriction would = more power?

 

+1 what he said, and yeah that car is a fully loaded plus Navi

 

im still stickin to what i been sayin....but the numbers dont lie....lol

 

this is great... 104 here i come

 

^^^^^fail.....101 like **** boi....lmao

 

I really don't know how much you'll gain without being able to tune afterwards but I'm betting it'll be a decent improvement.

 

dont really see alot of maxima's on the track alot of traction issues

 

theres like 7-10 of them here almost every week lol
