4" DP Dyno

[93H22ACX]

Well..its not a really good comparison since i wasnt tuned on the 4" dp and it was just bolted up....

Boost was spiking up to 30psi and it blew my ebay 90 degree coupler <_< so we had to call it a day..... didnt get a chance to set my boost controller (once it hit 22-25psi it'll spike to 30psi) at all and fuel pressure was mmmm not right either....

the 4" DP made alot more power up to 80-90mph but once boost spiked...the power was lost....but you can see its like 40-50whp more

We'll get it tuned again at balance soon so we'll really get a good comparison. Here's the dyno sheet from yesterday and a dyno from Dyno day..both were at Mainstream Performance...

Thanks to charles and mike for letting me use their dyno....and danny and peter for moral support and fixing my map sensor LOL...


The lower dyno sheet (615whp) was only reved up to 8500rpm.... the motor is reved up to 9500rpm during races....and this dyno

Full boost at about 6200-6300rpm
