How much power and torque do you think this custom cam will make over the tsp220r
also do you drivablity will be better

 

You will make more torque and very similar horsepower. You will get the power 3-400 rpm sooner. It will be a better cam in everyway IMO.

 

Sorry buddy but that is kinda a blanket statement. The peak TQ will be less and the peak HP significantly less.

The lobe patterns are significantly different. The 220 XER lobe is considerably more aggressive then a 220 XE high lift lobe and cannot be compared in the same ball park. Since it is just the .050 duration, take a look @ the duration @ .006 and .200

Also when the valve events are taking place, make a big difference.

Still feel your best bet would be a XFI 214/218 or LSL 215/219 on a 110 LSA and the ICL depending on what you want your DCR to be.

The lobe pattern for the LSL and XER are more in the same ball park as well as the XFI intake lobes, the XFI exhaust is in-between a XE high lift and XER if you want to say. So you can better compare the duration @ .050 since they are similar also @ .200 and .006

The XE's have there place too, but if he was already considering a 220r then upgraded high end beehives is not out of the question. Also the XFI and LSL lobes are easier on springs the the XER despite the higher lift.

hey guys I truly do appreciate all the help
Its guys like you willing to help is what makes this site so cool
But i would like to keep it some what simple lol
Im ordering my convertor tomorrow 3200 circle d
And i have narrowed it down to pretty much the xr265hr 212/218 on 114 or the tsp220r 220/220 on 112
Mainly because ive done a bunch of home work on both cams and they both seem to work really well

 

I would agree with you if we were talking about a truck with better heads and shifting higher. However, the torque made from 3000-4500 rpm will be significantly better vs the tsp220r. The peak torque will be a difference of what 2-5% and peak horsepower will likely be what 2-5%?

 

Those are two very different cams.

If you don't trust us then go with a custom grind from Geoff, Patrick G or Brian Tooley...

The 212/218 is not optimal for the 4.8/5.3 and neither is the 220r, advancements have been made. Benefit from them.

Or go the "proven" route or have the correct cam for the job and be done with it. What to the fast guys do? Custom grinds, I rest my case...

You go with the 212/218 you may feel you left power on the table. Go with the 220r you may not like how late the power comes in.

Up to you man, just trying to help.

My suggestion VS TSP220r

Intake Lobe Profile XE 218 vs XER 220
3712 271 218 136 .331 .059 .048 .497 .530 .563
VS
3720 269 220 143 .342 .062 .049 .513 .547 .581
Exhaust Lobe Profile XE 222 vs XER 220
3714 275 222 140 .333 .066 .054 .500 .533 .566
VS
3720 269 220 143 .342 .062 .049 .513 .547 .581

 

Also I agree on the TQ coming a bit sooner.

Even a margin of 5% is significant.

 

Double post...

 

Im all ears guys lol i love to learn and im open for any and all advice
Im just a little lost on specing cams
