I suspect if you run e85 and ramp the boost and power on progressively it might be ok. The stock turbo is superior to a pulsar or anything else for that matter, up to around 440rwkw. Don't touch it unless it is damaged.

bodhi03 New Member 15 Member For: 3y 6m 16d Posted 01/10/21 07:38 AM Author Share Posted 01/10/21 07:38 AM is there any way to minimise the motor from sh*tting itself? like for example more cooling or whatever.
