I am in the proscess of trading my Savage for a Hellfire. both are rollers as I am keeping my LRP .28 to use in the hellfire. I'm sure someone on here has used this engine in their HF. how does it perform in the truggy? do I need to do any upgrades to handle the power? it was an awesome engine in the savage and I imagine it will be great in the HF. I will probably need to replace the front diff since the guy that has it now thinks it is getting worn out. what is a good replacement diff to use? and what weight oils do you all suggest I use for the diffs? I will be just bashing with it so I would guess that the heavier the oil the better? I have had several nitros over the years but this is my first truggy. is there anything I should know?
Thanks
I had the lrp28 in my HF before upgraded to os28. The lrp is great for bashing. I used a 14tCB and stock spur. It had excellent bottom and mid range and a good top end. Great mill for bashing in a truggy.
Some people are using the stock diffs (shim both pinion and ring nice and snug) with good results (i had bad results).The best upgrade diffs are the hot bodies spiral diffs(lightning etc) and the CEN GST diffs. I recommend the GST diffs (i use). They have extra large teeth and are strong (you still must shim!). The pinion/crown fit straight into the hellfire cups with shimming. They change the gearing ratio so you have to drop your clutchbell size. Iam using a 12T CB. I tried 14T and it had crazy as top speed (os28). The 12T gives a good bottom/top.
Since your just bashing i say aprox 7/20/5 oils. Iam using 7/100/7 at the moment. The high centre oil gives the truggy more all wheel drive but is bad for turning. Racing 5/7/3 or similar.
A truggy is way better for bashing than an MT,IMO. They jump better, turn better and can handle higher power engines.
Thanks for the info... did you have any trouble with the pullstart on the LRP being too big? or was yours a bump start?
Now i remember, thats right. The bottom of the pullstart plate is slightly too big. Mine just fitted but i couldnt move the engine across to use a larger clutch bell because the screw/edge was in the way (if i remember correctly). I know others have shimmed the engine up slightly with washers or used some alloy or similar, or ground the bottom edge off.
I just went and checked as i still have the lrp parts. The only reason the screw hit was because i had extra long engine plate screws coming up thru the plate and the right side pullstart screw just hit that. If i had used a normal length plate screw all would have been ok.
