So, with the New Rotrex kit now installed along with upgraded 1340cc injectors we are only seeing 550whp @14 psi which is the same thing we saw with the previous kit. Car is still in the shop at RT Tuning. They have been in contact with Aaron so we'll see how it goes going forward. I was also told anything above 600whp on 93 might see some detonation. My goal was 625wph to 650hp on max boost but if we can't get there, I may be looking into methanol injection. If anybody has any thoughts or suggestions, I'm all ears. Thanks!

Use E85, it's much safer, burns cooler, yields more power and in a safer way.

You need the sensor. I am using Zeitronix kit from SpecialtyZ, call them or email so they can send you the correct parts for your setup.

E85 stations

Should of went with a turbo if you’re expecting those number out of a blower using pump gas.

I am also planning to eventually bump the power to around 625 - or at the very least 600 - using pump gas. Top Gun mentions on their website that this should be possible with the kit, so fingers crossed...

I do have E85 at a few stations near me, so I might go down that road in the future if need be.

Unfortunately, E85 is not readily available in my area.

Best of luck to you! I have every supporting mod required and we were limited to approximately 570whp at 16 psi, hence why I am adding the methanol injection.

That sucks. I made 585whp at 12psi with turbos. I didn't even push it though because it is 93oct.

What is the tuner saying the limitation is on your car?

The lack of a twin turbo kit.

From my understanding, they can't get any more than 16psi and mentioned a fear of knock with anything over 600whp. Not sure if my tuner is afraid to bring it up more or if this kit just doesn't live up to the hype. I'm definitely not worried about pushing the limits.

I run 17psi on pump 92 with no ignition correction, it's fine but you have to retard the timing so much that the car honestly feels like **** regardless. If I recall right at WOT it runs 8 degrees of timing and that's it.

I also contemplated meth injection as well but there was so many cons to running it I didn't want to deal with that, so I had a 55 gallon drum of e85 delivered instead as there's zero locally available e85 stations.

Aside from the cost of initial setup, and having another fluid to occasionally fill up.
A proper WMI setup has no cons.

Are you using a Wastegate setup or trying to control boost with Ecutek and the BOV?
