Porrted Boss w/E85 VS CJ & E85

[okc12silvergt]

Ok I need some opinions on deciding what to do next on my car. I have full exhaust Boss intake and tune currently. I have 47lb/hr injectors ready to go in to run E85; I am just waiting to put them in before I decide and have to waste a $200 on a tune. Should I

A. port my boss run E85
B. Buy full CJ intake setup and run E85 on it

Opinions?

Save the money and go FI.

^^^Yes that or stick with Boss and tune for E85...Gains with CJ manifold over E85 tuned Boss setup are marginal.

Yea maybe 15whp difference. Here is my thread. http://www.svtperformance.com/forum...-Intake-Manifold-to-Cobra-Jet-Intake-Manifold

Essentially a guy with CJ setup and catless X (stock headers) versus a guy with Boss setup and LT's will be a dead even race...With similar drivers/skill...I'd spend the money on LT's combined with Boss setup that's a pretty effective combo...

Depends your end goal.

Here's best CJ vs Boss test I've seen...On same exact car with exact mods the CJ setup picks up 5whp over the Boss IM...

Port the Boss, save the $1500 for a Paxton

Port the boss, get off-road pipe and tune and injectors if you don't have them already call it a day. Headers and CJ might net you 15 more hp and 20 Tq but for $ not worth the hassle

But the CJ also negated the small loss of Tq. I'd like to see the graphs overlaid to see what the power under the curve looks like and see where else it gained besides peak numbers.

The thread that I posted shows that the CJ gained midrange over the boss on HP and TQ.

Looks pretty solid to me!

And by small you mean an amount that even the butt dyno won't notice lol...I'm just saying that if you've already got the Boss setup, then build off that and don't spend the $1500+ for the CJ. Not worth it IMO for a couple whp here and there, and marginal amount of torque gained. Like I said above, the guy with CJ and stock headers(with catless X) versus the Boss with LT's will be a VERY close race, with Boss/LT's possibly pulling ahead.

I just installed my CJ intake i have cat deletes no headers. And the thing pulls like a freight train. Been in a few boss cars didn't have the get up and go as my CJ car.

Would like to see some track times of both setups on the same car for comparison sake

 

[Jabooh1]

Your not going to realize the full potential of the CJ setup unless you get better heads and cams. If you don't do that, it's a waste of money.

 

[Fastnature]

I would like to see test of CJ on a turbo car vs stock intake

Agree
