Hey Guys.

I will be upgrading to a new set up in a few months and looking for some advice.
New turbi kit with Morrison Fab T4 mani with EFR8474 EWG.

I currently have a Skunk2 intake manifold and was thinking of perhaps changing to the Magnus V5.
Car is more a weekend driver street car and some drag time a few times a year.
Will the Magnus be a good choice for this or is it going to shift the power too much to the right ?
My power goals are around 750+whp but want "some" usable power, not just a high peak power.

 

Magnus is recognized by English Racing, by UK tuners such as Norris Design, and many others, as leading intake manifold for high power applications.

The changes once you fine tune the car again, after Skunk to Magnus V5 swap, will likely be modest, maybe 20 whp higher peek, and +500rpm extended peek power, with maybe slight loss of low-end torque, maybe.

 

The main thing you'll notice which most people fail to mention/realise, is longer time-to-boost.
The larger plenum takes longer to fill, so boost will take longer to build (in every gear).
And the shorter runner will shift the power band to the right.

If you want a punchy car, stay with the Skunk2.
If you want all out power where the power ramps on a bit smoother, then Magnus.

 

Great thanks, exactly the info I wanted. Will stay with the Skunk2

 

If youre changing the intake manifold its basically- Magnus > everything.

We have multiple cars here on a variety of 800whp+ setups with magnus intakes, and I would never claim any of them lack... "punch".

 

The punch may still be there but at 6000+rpm ?
if it shifts the PB too far right then I'm not happy with that.

 

have you done any "time to boost" testing on the road before?

Great thread of a Skunk2 getting absolutely smoked by a Magnus.

 

i had a AMS and liked it to.

i would absolutely go with the Magnus if the $$ dont bother you.

 

I've got the AMS F1 intake manifold with 68mm Bosch DBW.
I love it. It makes more power than the stock manifold for sure, but it definitely doesn't have the same "time to boost" response.
E.g. it takes longer for the plenum to fill, so the boost doesn't ramp as rapidly after throttle application

 

i had a 2.4....with a 6870.
it didnt have that issue.
