Sweet man. Let us know how the mxplenum and setup goes

Let us know what the tuner finds

Could Add a big external gate to the housing, should help relieve some manifold pressure and let it breath. Or bigger turbo as eeryone has suggested. One other thing, what spark plugs are u running?

Kudos motorsports website Get the complete kit including tensioners, water pump and crank/cam seals

Ryno- do u have a comparison dyno graph of the freddy and the mx setups ?

Explain the issue a little more please. If the fuel pump wasnt supplying enough fuel at cruise u would expect the same on boost which means ur issue would be on boost as well. Im thinking it may be an 02 sensor issue. Try disconnecting the 02 sensor and going for a cruise to see if the issue is still there

Ron check for leaks first. Give all the cooler pipes etc a nip up. Also have. Been testing on extremey hot days? As the boost will be less due to the air density being lower.

Arrydjay- did u check what ur airtemps may have been getting up too?

3076 turbo

Awesome results mate. Hurry up and go to the drags I considered cams Hows it feel on the road?

The speedo is mechanical, so all it has is a speedo drive in the gearbox - a speedo cable - speedometer in the cluster. Pull the cluster out slowly and check the cable is still inserted in the speedometer. While the cluster is out drive the car forward or backwards alowly and check if the cable is spinning, if its not the it mean either the cable or speedo drive has an issue

The exhaust pulses only happen during the exhaust stroke. Turbo spinning at 125000rpm or so and shattering gets thrown back up the exhaust ports and enter the engine. Has happened more times than not unfortunately.

My freddy plenum has been ordered. Only changes will be injectors (740's maxed out) and cooler piping. I will keep the same boost as a back to back comparison.

Check spark plug condition

The diff and gearbox have filler plugs on the side. These are at a certain level therfor u cant over fill them if the car is level

Possibly a fuel pump issue

Dont drive it untill u have checked turbo's. if it has popped and u keep driving the engine can ingest ceramic dust leading to a rebuild. Remove the speedo cable and check its condition. Its common for them to break Read the attessa code (flashing LED) under rear parcel shelf and then google which fault code u have

??$$$???

Will post up the dyno sheet from Kurtis's car if he doesnt do it before me. Sorry have been flat out in the shop.

Boost leak has been fixed since then Deano, the bov he installed was poo. Was leaking at 1 psi with the smoke test. But yes its a nice linear power curve not a lag monster

Mines an rb25

If it reads low dont go and drive it to see if its gonna read different. Top it up so it reads full before driving

Can u post up a pic of ur dyno sheet Ron

Drift pipes change the sound alot too

Lol Ron, 4000rpm is not laggy
