what would i have to do to rev the car up that high? just rod bolts? would you even try it on a 98? every friday night from spring to fall me and my friends go to the track, so it would probably see alot of track time too.

 

Most customers run that camshaft without worrying about rod bolts. If I was going to spin over 6700-6800 I'd think about rod bolts though...

 

I have Katechs

 

I did consult graphs. That's how I go the 6250rpm peak figure for the F11.

F11, Stock heads


F11, stock heads, vs ported


F11 Stock heads, cats


F11, stock 243 heads

So, how is the F11, not comparable to the TR224?
It puts out, over and over, 10-15hp more, while retaining a decent tq curve.

 

Jason Torquer V2 on a 113 peaks at 6200ish....You said it could be shifted at 6400....What would be the best shift point from a track perspective...

Im running 3.73gears and a 4000...but this is a daily driven street car in the summer.

I was considering this cam also I just did not really want to shift past 6500....I don't really want to spend the time replacing rod bolts on this motor....

 

hey south, thanks for the dyno graphs. Those are definately helpful!!

 

I don't know much about the cam but you might want to rethink your decision about the rod bolts since you have a 98.
I got a call from our shop(SN is "SRP" on here) last year asking to come down and look at what was left of this LS1 block that came out of a 98 TA. The #5 and #6 rod bolts had let go in this thing at high rpms and the block was toast. I had them change my rod bolts(to ARP) and rod bearings while they were making my true duals and my #5 & #6 rod bearings were starting to show abnormal wear compared to the other six.
My advice- if you're gonna run a 98 up past 6000 rpms, change those rod bolts. Do a search on here, it's actually not that hard to do.

 

Do you guys even read any posts.??????

 

Well i am willing to replace my rod bolts, but would i have to replace the rod bearings while im in there? I am prolly going to do a cam liek the f11 or so. Just to be on the safe side.

 

nope, just the bolts, 1 rod at a time, 1 bolt at a time.

 

No problem!

 

hahahah where is the comparison overlay where it beats the tr224? I can show you graphs as well but until you get a similar car side by side on the same dyno you dont have proof of anything. I have an overlay of a tr224 vs an fm13. Both xcar are almost indentical in mods. The tr224 outpulls the fm13 all the way to 5800 rpms. Then the fn13 catches it and has 10 more peak hp after 6000 rpms. It aint better until you get to the rpm range. Are you gonna run your car at 6000-7000 rpms all the time? THIS is where the serious thought comes into play. At what rpm range are you going to drive your car?

 

Bah! The F11 will make tq and hp sooner than the F13.

 

I have one with TR224/G5x2/FM13 overlay with similar results under the curve, but above the curve 5250 things start to change.
One reason I say for pure street 22x range cams are plenty, but at the track, the big boys will shine.

 

I ran the TSP 231/237 and spun it to 7000 on stock rod bolts in my DD. I now have the TSP MS3 and will do the same. The torquer will be fine for daily driving.

 

These are the numbers from an fm13 vs a tr224, done on the same mustang dyno within a week of each other by the same person under the same weather conditions. One car is a 99 ss the other is a 01 ws6, both cars are almost exact in mods.

line graph goes beyond 5600 rpms, this was a print out of the numbers. I'm sure I dont have to convince anyone the fm13 had more peak.

 

Your car looks REAL street 4thgen
Come on man, DD for you is if it starts

 

This is great data to look at. Thanks!

 

Daily Driver is used loosely nowadays. My car starts and runs every day I drive it. It just might not be every day. And I can drive it anywhere on the street and be legal.
