Safely without stressing to the point of blowin a hole in the block..
I have a walbro255 in tank..H/C that dyno'd 441whp..
I was wanting to do another 75-100 shot wet kit..but just curious on what I should expect? or should I wait till I start putting together another motor..

How much have you ran?
How long have you been running it?
How many miles are on your car?

 

1. 225 so far on stock bottom end
2. few months
3. 51k miles

However all these question have little relevance in the longevity of the motor. As you research more you will find that there are several factors that some into play on how to make the motor last, the tune-up being one of the most important.

2. 2009-125, 2010- 150
3.103k

 

Carter.. What kinda power did you put down on the cam only..And have you ran the dyno with spray?
Are you running the 225 shot on top of the cam only!
Dang man I was thinkin of only trying a 100 or so
Ive got 53k on the car so i thinkn the motor is still strong..

 

Made 391 rwhp cam only with the auto.

have not dynoed with the spray.

And yes, 225 on top of the cam only setup.

 

Nice numbers..So I guess ill bump upto a 125 then..Is yours stand alone or do you just run high octane? And Im assuming your Nitrous tuned

 

No standalone, ran pump gas on 150 shot, went to 112 on the 225. Probably over kill but I want this motor to live.

As far as Nitrous Tuned, well i have a good NA tune and I adjust the timing/fuel via plug tuning.
