Cobra Jet intake going on stockish auto 5.0!!

[burnin4]

I like that idea as well. I'd hate to do the cj set up and still not be happy. If I could have a high 118s trap car to low 20's I'd be content. That would do some damage on folks. Having with cammed ls cars and the new c7 and the older gt500 would be fine. Would this set up get me there?

My 14 GT trapped 120+ with just longtubes with a full exhaust, cold air intake, set of Welds, and an email tune from JMS. I've since been retuned, and have a BMR k-member/A-Arms/Chassis brace/Radiator support, expect to go 121-122 in average weather. I really want a CJ intake but going to hold off for a TVS setup.

Very, very nice times! Thanks for the info.

OK, what would you go with on a bolt on car? 3c? Or 4c

5C if it's n/a
4E if it's n/a and CJ or cammed or both
4C if NOS
3C/B if Blower/Turbo

It's na, but DD and will mostly see spirited driving, few races, track once a year.

You will notice very little difference in DD between a 4C and 5C but will see big difference at track
Even my 5800rpm 4E stall was not bad on cruising on streets at all.
You will see converter lockup at 30-35mph under mild throttle so there is no slippage issues.

Got Ya. I'll check into it,just nervous about it since it is my only car.

What is your exhaust set up, sounds awesome!

I see the CJ intake hurting 1/4 mile performance of an auto trans car unless it has a very high stall and steep gears.

Gears aren't a issue as 6r80 has really low 1st gear
Converter I can say from personal experience you are correct but it applies to Boss and CJ alike on needing converter to see the gains.
I ran a 4E that stalled @ 5,800 rpm according to my datalogs
With a 4C it bogged.
I had stg3 cams though

Do you have that time slip?

 

[clc44]

Right now I'm thinking full exhaust, converter, aluminum ds, tune and call it a day.

...and gears.

IMO, cams offer much more bang for the buck than a Boss or CJ intake.

gears do more than just help 1st gear.

Cams offered me no gains in a coyote at full weight.
Most CJ intake guys went just as fast as me with no cams.
Coyotes gain little to nothing with cams unless you do a lot of weight reduction and spin it to 7900-8000 rpm.
Coyote VVT makes them unlike older 4v that gained from cams.
No need for gears at all.
The fastest n/a guys are auto 3.31 gears and the 3.31 offers very little gains over the 3.15.
I have done both personally on the CJ and cams.

Burnin4,

Can you PM me about your tune. Im running JMS right now and had a couple questions about your datalogging.

 

[sspstangbanger]

gears do more than just help 1st gear.

My shift rpm drop was almost identical with 3.15, 3.31, and 3.73
My top of 3rd gear was 131mph on a 3.31 gear

the right cams/tune offer great gains.

Dyno sheets?
Timeslips?
Even without limiters the torque loss hurts cammed cars without major weight reduction.
If you are talking a coyote swapped fox or new edge that's different than a s197 chassis street car.
I have had tuning done by two of the best s197 coyote tuners Mike Rousch(Map) and Jon Lund/Ken Bejonnes(Lund Racing) and they both concurred with the torque losses.

Stock intake stock cammed s197's have been 10's also
It's not worth the expense in a s197 chassis street car that weight 3,400+lbs less driver.

Limiters and vct deletes both reduce tq down low. The goal should be to increase the tq in the rpm range seen in the quarter.
