Last week I performed a baseline run of my 426 Jeep running Gen1 Mondello Heads. The dyno sheet compares last week to this week with the Gen2 Wet Flowed. All three runs last week were within 1-2 hp of each other. The shop performing the pulls is Integrated Performance and they have a dyno that sports four (4) rollers for two and AWD vehicles. The vehicle sits down between the roller rather than on top a single roller like a DynoJet. It is so refreshing to have the beast sitting down in four (4) rollers versus bouncing around on front and rear single rollers like a DynoJet model. The DTS doesnt throw the big numbers a Dyno jet provides, but close enough for checking my preliminary tune from [email protected] Needless to say I was pleased by the back to back consistent results!
I finally received and installed the Mondello Wet Flowed Heads on Saturday 1/10. Upon opening the box both myself and my LX car buddies couldnt take our eyes off the reworked combustion chambers. They are simply a work of art! Upon removing the Stage 2 Gen1 heads the block revealed deep gouges at the 12oclock position of 4 cylinders...I was not happy...... but shes making power so.....thats for another discussion about strokers. I redata logged and promptly sent the results off to Bob at SVS. He let me know the tune had now significantly changed. I went with a second preliminary tune because time was running out and my appointment on the Intergrated Performance DTS AWD dyno was scheduled for this morning at the same time as last weeks baseline run.
Judge for yourself by reviewing the attached dyno sheet. Quite an improvement for just changing the combustion chamber a tad.
As previously stated, the DTS eddie current doesnt throw the big numbers a Dyno jet provides. This dyno really loads the engine down and you can hear it grunt and strain against the preloaded parameters. I've been around the so called "awesome" tuners and watched the old Dyno Jet model spin its bearings to a frenzy!
There is no doubt when Bob receives the data logs from the dyno and subsequent run back home, the HP/TQ will rise, but for now, having a, or the only, naturally aspirated Jeep, clicking 503hp/482tq with a 22% drive train loss is nothing to be ashamed of..LOL!! I guess old Joe Mondello know what he is doing!!
The test was with conducted with 91 octane unleaded fuel at 188-190 degrees coolant temp.
