Ive looked around on the fourms and there really isnt any extremly helpful threads about the tweaked Manis and the results they give! The new ones will be in next week with a new tune from Eurocharged! Ill keep this updated if anyone is interested! So far taking off the parts was cake to do!
Rob is a great guy and makes the best!

 

I would keep something between those plenum mounting faces, all the tweaking in the world will be worth nowt if they get dents in them.

 

Cool bud! Let me know how it all goes. Lets skype later aswell.

 

Mine are the Needswings manifolds, not the tweaked and I have before and after dyno numbers tucked away somewhere. If memory is correct it was 16 hp gain throughout the curve from 3500 to 6000 rpm.

The big ones only gave 16?? I was hoping for 20+ with the tweaked..

 

That was with the same tune as before the manifolds.

Les

 

Oh ok, that makes sense! Had me worried for a second

 

I don't think I've added many mods since I added the Manifolds ..... well, headers. A few retunes. I'm around 350 hp at 6000 rpm on a Mustang dyno at sea level with temperatures in the 90's. At 6400 I'm at 370 hp. The manifolds leaned me out from 11.8 AFR to 13 AFR. You'll need an adjustment to your tune.

Les

 

I thought just eurocharged tune was enough?

 

Eurocharged is my tuner. Since your manifolds are the tweaked ones you may be OK with the same tune. My car's tune needed tweaking after the install. (more gas) You won't know until you get yours on and check the AFR's.

Les

 

No, he will need to tune for the "tweaked" mani's or he will have no gain... 20 is possible...and hang on, because your hole shot will be a tire eater...

 

Yep i already have my retune ready to go.. ill have mid-high 11 second Daily 😃😃

 

you must know something I don't about mid high 11 daily....

 

Mid-high.. like 11.7-11.8

 

High 11's isn't automatic, it takes a lot of perfection from the driver. More power is a great thing but knowing how to get the most out of it is a huge challenge. My mph says I should be much quicker than I am but I just don't have the ability to get it all ..... yet. Enough blowing hot air, good luck and be ready to do what's needed. The manifolds were huge for me regardless of how you view the numbers. I'm one of the few to put my car on the same dyno after every single change to my car. No BS, just facts. Be happy .... and fast.

Les

 

This all 100% right! Im just saying by my mods it would be possible to get those ET times! Either way its fast

 

So what are all the mods you have made? 11's take quite a bit of work and good conditions.

 

The same as all the others that run 12.2-12.4

 

Needswings DCAI
Eurocharged 65mm pulley
Eurocharged tune
Heat Exchanger/supercooler from needswings
Needswings catless cutout downipes with custom retune
Custom bigger intake filters
Tweaked manis
Teflon y pipe
Another retune
And im even at sea level... So high 11's are very possible

 

You should know that Robs' Crossfire with all their mods runs 11.97 according to their website. He has since sold it so no improvements will be forthcoming. Still, if you hit 11's you should feel good. I am running a stacked setup with upgraded fuel pump and AE regulator and a few other performance up grades, porting and polishing, etc. and a tune from Inmotion, so I would expect you to run 12.1-12.2 at 118-119. Nothing to be ashamed of at that.
