Yup, the old V-10 sitting close to your knees problem. Previous owner added another carpeted floor mat under the original mat, that seems to keep a lot of it away. Also be
sure the "doghouse" is sitting properly and latched properly. If it was removed it may be off kilter. That's a lot of motor real close. I believe they could have done a better
job of using heat shields to deflect the exhaust heat away . I have considered fabricating an air dam to bring air up into the engine compartment that could mount
underneath. I could sell a million of them.
i have a polaris ranger side by side. That thing has horrible engine heat by your feet.
