Mustang Dynos read lower than DynoJet and Dyno Dynamic reads lower than Mustang. It's probably more than 600 at the crank.

Cams are good, you need cams..........cams..........and more cams......

E55 RUSS

OK...which Cams then ???

Am I just being paranoid. I just don't understand why it makes sense to open your engine and put in new cams for 15hp. Will it really make your car that much faster? I think a larger heat exhanger, stickier tires (to put the power to the ground), and other mods to focus on keeping the engine cool make much more sense. Can someone please prove me wrong and show me 1/4 mile results before and after cams.

SleeperX

and less weight. My next mod....

Sleeper how much is your E making to the rear wheels if you don't mind me asking?

Give me 2 more weeks...I am the test mule here in NYC.

don't worry, i'll get you some 1/4mile results. unfortunately they won't be direct comparisons until summer is over because of our extreme desert heat. based on my experience, even with the limited data from this dyno run, i fully expect a MINIMUM of 2/10th and 2mph from the cams.

you also mentioned stickier tires. i've only run on street tires so far and i believe i was near their limit before the cams so traction may become an issue now. if so, it's entirely possible that my future 1/4mile times may actually suffer without moving to d/r's.

keep in mind, you're not really opening the engine up. they're pretty much a bolt-on upgrade. cooling mods are definitely a good thing and no one could criticize you for going in that direction.

i am paranoid also bro thats why i started this thread to see what people thought. i agree with the rest of your post also but damm i already did all that and some. there are no more bolt on mods left to do. unless you call nos bolt on.

2/10 of a second doesn't excite me considering that I can see that variability depending on track conditions and launch. 2 mph does get me very excited, but can one really expect 2mph from 15hp. Question: I believe Rock got 125mph trap speeds before cams. How does he achieve this? In my opinion cooling and weight reduction are better mods. I for one am anxious to see VRUS' new heat exchanger mod in action. As for further upgrades, I don't think they are necessary. If anything you have too many considering the cars limited cooling capacity. At this point we are seeing diminishing returns from addtl mods. Why do you think stock cars and stage 1 and 2 cars are so strong at the track. I hate to bring this up....ughhh, but why is there a video of an M6 walking a stage 4. COOLING! At this stage we need to think about cooling mods..

MIG-E55Rocket,
Before you put the cams in, get the ECU flashed. You have a beast already my friend.

V12Godspeed

I will....I have an intercooler so big, I am affraid it won't fit in my car, lol! I am working on that already...hehehe

2MANYCARS

Mig,
Good luck to your project, you will hear burbbling noise once you have the cams installed like mine. How big is your intercooler? I bet it's not as big as my APS intercooler on my EVO.

ROCKETW19

i already have the heat exchanger and pump upgrade + the 10deg star mod also. i think the kleemann car already reached the speed they were racing to. i dont think the kleeman guys are that stupid to not know the pump was out. besides even if the pump was out the M6 caught up so fast he had to have let off.

SleeperX

Yes, but I think a big heat exchanger would allow the car to produce even more power.

E55 RUSS

Everyone talk about cooling and etc...but I dont think Kleemann, MKB, Carlsson, Brabus, Vaeth, Evotech are stupid enough not to include cooling MODS in their stages...

Infact only MKB offers bigger cooler on thier 680 HP 55 and Evotech on their 700HP beast...but any 55 below 620 HP do not have any additional cooling mods with all major tuners...They put Cams before cooling and do work on transmission ECU and reinforcing...and Cooling is the last mods they do...

ProjectC55

Still I think cooling would be the best mod for a modded 55. After I get the best cooling application done I would inquire about cams. This is the same premise done on high hp Turbocharged cars.

More boost ,then you need a more efficient intercooler to dissapate the heat.

Bigger Turbo,then you go cams and bigger intercooler.

Hi, guys. Got the dyno results today. 439 HP, 443 ft lbs TQ on a Mustang dyno. The car has SLR cams and VRP 80 mm throttle body.

Some more details here: https://mbworld.org/forums/showthrea...32#post2152032

ROCKETW19

with no base line the info dosnt help! but thanks for share anyways.

jmf003

Yeah, I had planned to have a dyno done before my first mod but due to a scheduling glitch, it never happened.

Other forum members have posted results of 390 HP to 410 for their stock 55K engines on a Mustang dyno. If my car was in that range then I'm getting at least 30 additional RWHP from the cams/TB combo.

So it's not the hard data that you and others would like to see but it's consistent with the notion that the cams are adding 15 to 20 RWHP to the engine.

SleeperX

I have to disagree with this statement.. I bet the TB added at least 20-25rwhp.. Implying to me that the cams added about 5-10hp... but then again this doesnt mean much without a baseline...

chiromikey

imho, i don't think the tb is going to show that much hp on a mustang dyno...more like 12-18hp tops. but i could be wrong...at least my wife tells me this all the time.

SleeperX

There is only one way to solve this.. time slips....

Hi, Michael! Thanks again for the spacer and tech info. The installation went smoothly and I'm lovin' the results!

SleeperX, the TB install definitely added a significant amount of HP to the engine. The car was noticeably quicker after the install.

Renntech claims their 80 mm TB will produce +15 HP (difference between Stage 3 and Stage 4) to +20 HP (standalone claim) which is close to the numbers you've suggested but a little lower.

I also used the lowest possible figures when I made my "at least 30 additional RWHP" comment. If stock 55Ks measure at 390 HP to 410 HP, my increase was in the range of +30 HP to +50 HP.

Using your numbers of +20 to +25 for the TB, the cams would have produced +5 HP (worst case) to +30 HP (best case). Midpoint of that range is +17.5 HP. Using Renntech's numbers, the cams would have produced +10 HP (worst case) to +35 HP (best case). Midpoint of that range is +22.5.

So no guarantees but I really do believe the numbers are consistent with the cams producing +15 HP to +20 HP.

There you go! We need a Pinks All Out AMG episode.
