    M52tub25, race gas and lots of nitrous?

    How much nitrous will a M52tub25 take? We are going to run C16 with the factory tune. It is a port nitrous system. Starting with a 125hp shot and working our way up to 200hp if it will take it. It's for a drag race application. Some Amazon headers to get the exhaust out. Has anyone pushed the M52tu beyond its mechanical limits?

    Main problem with m52tu is pulling studs out of the block. I would say 200 shot is the maximum you can do without $#@! hitting the fan.

    There was a time people thought a 125 shot would kill an S54 and look at the M52U handling it no problem!

    We were going to take it back to the track last month but I got sick and we didn't make it. So next event we will spray it with a 175hp shot.

    Still waiting on them to schedule the next event. If they don't do it soon we will just take it to a test and tune.
