hp is the goal, supercharger is the only option i have found so far

I went with Dinan. They had several more mods when I did mine but they still list engine software and a bigger throttle body.

If you add low restriction exhaust along with the Dinan mods you would surely notice the difference.
About a year ago I searched for supercharger and turbo kits I could install. I never found either. Next step was to get two quotes for custom installs of each.
Both quotes for custom supercharger were around $10,000. The install would take 3 weeks with no time estimate for tuning time.
The estimates for turbos were both for twin turbos. One estimate was $8,500. Down time was about the same as the supercharger. The other estimate was from STS. Their install would be under the X.

I didn't do either. The route I went was Nitrous. I have a 150 shot with methanol injection. The nitrous won't fire if the methanol tank is dry and only at full throttle. The methanal synthetically increases the octane to around 104 so I have eliminated the risk of having it run too lean---nitrous + lean condition = big boom. HP is 525-540 depending on the dino and no one believes me when I tell them the torque numbers. They tell me if they are true the transmission would blow.
I show my X at the Dallas Cars and Coffee. Lots of lookers and many smiles and come look at this.
