what are the steps i need to go from my sequential setup to inline, just take out the butterfly? i need ab oostcontroller too right?

 

if your sequential works fine DONT go the parellel... it sucks ***

 

they dont , my second hits and i justhear air blowing. not sure whati s wrong
but has no leakage. any ideas?

 

Try this...

If you hear air blowing but your not getting any psi you should check your plastic elbow, your most likely leaking.....

Honestly, only go parellel as a last option. It ruins the fun of the car. IMO

 

If you have a boost leak, going non-sequential isn't going to make anything better....you'll still have a boost leak.

 

then is there even a benefit?

 

There's a difference between a boost leak and a problem with some aspect of the twin control system. Most people go non-sequential because:

- they have problems with the twin control system that they can't solve.

- the transition tends to get more violent as you mod the car and raise the boost. Non-sequential obviously eliminates this

- they regularly road race the car and the non-sequential torque curve is more predictable with no surprises

- they are deluding themselves thinking that non-sequential is more fun in street driving.

 

I agree.

Mazda Australia raced there FD RX-7's in non-sequential form for the 92-93-94-95 Bathurst 12-hour. This was to ensure a predictable torque curve & get every last ounce of power from them.

Having driven there 95 race car both on the track & street, it was a complete dog until after 4000rpm & I would have hated it if it were a street machine.

 

wow ,thanx guys, so maybe a vacuum line is hooked up wrong?

 

infact!!!!!!T the seoncd turbos intake... thats the wrong way.... you can hear it boosting OUT the second intake!!!!!

 

Huh

 

Sounds like your CRV isn't closing for your secondary boost.

Look at the area for the secondary boost.
