If only Lake Havasu wasn't 6 hours away, 2 toddlers can make that drive seem like it will never end. But it does give me an excuse to drive to Vegas

This is my dyno from yesterday with a 6.2 Whipple set up with a stock air box and stock manifolds.. just Cat Backed. I am having 2 inch custom American Racing headers, cold air, catch cans with a new custom tune don't today. Notice the Boost PSI readings with stock manifolds and air box. I do not intend on changing pulleys to increase boost so my new dyno on Wednesday will tell the tale.....

This dyno chart confuses me. What is happening at the 4949rpm mark to cause about a 129hp drop?

I know reading dyno sheets gets really confusing sometimes. The drop you see is the converter locking up at the same time the transmission shifts. That is perfectly normal and because we didn’t tune it originally we didn’t have it set to lockup during the pull. You will notice the final dyno sheet looks different also because in the software we will lock the converter during the dyno pull.

 

The above was explained by my tuner, I hope this helps...

 

The truck should be on the dyno again this afternoon !!!!!!!!!

Still running the stock air box KP is building me one but as you can clearly see the boost pressure is down due to the headers..........the truck is running Very Strong !!!!! Not loud at all very please with this current set up...However I just ordered a new pulley to get my boost back up....my goal is 600hp to the ground.

So the truck makes less power after the LTs??

 

I thought it would make the same power under less boost. Learn something new everyday.

makes more HP but less TQ.......made 47 more HP and 47 less on the TQ...and will make even less boost when I install the cold air.....but when the cold air is finally done, I will change out the pulley to recover the boost to the original boost level and recover MOST of the lost TQ....and more HP ta boot.... my goal is 600 + HP to the ground and at least 600 TQ....This is the ultimate sleeper truck....it will get a 3 gear scratch in auto mode on a greasy asphalt road...

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.
