nice numbers,who did your tune?

 

friend of mine thats local fellow evom member as well.

 

VD graph looks inflated past 6k. Probably closer to 450whp with your mods on the red...

 

looks good OP!

 

THANKS IT RIPS

 

i dont see how .i know he didnt do a helium injection at 5850 .

 

Holy crap, That is extremly nice.
Makes me feel good about my future setup with a 2.4LR and built head!

 

I have another log that registered 496/394, and that was after pulling a degree after 6k. Both done on same flat stretch of road.

My hks 264/272(puny... ) bbk full car registers 370/340 at 24 and 410/370 at 28 consistently within 5-8hp/tq on the same patch of road.

I'll admit it sounds freakishly high....but, I dunno. Back in the day my 50trim stock motor made 508 on pump/meth, and at the time that was freak, so I'd guess some cars are just more prone. His car does have a good bit of breathing mods done that I feel can attribute to it's power.

As far as the "inflation" past 6k rpm...if you'll notice the boost crept up to 27 for about 1k rpm, right where the tq curve came up...

 

God damn those are awesome numbers. Great mod list! Power makes sense based on the mods Op has done in my opinion. Seems a tad high on 93 but im not doubting it

 

it is inflated.. theres a hump at the end.. sorry OP but just trying to help you.. if you want ill show you the proof with my vd in smoothing 0.. theres a big spike at the end im sure.

on another note.. nice engine bay.

 

send logs to tscompusa@gmail.com ill show how its inflated. you can also reference this thread https://www.evolutionm.net/forums/ev...-properly.html

4th graph down is the same issue you're having.

if not show smoothing 1 and then show smoothing 10 of the same graph you just posted.

 

What causes the humps, bumpiness of the road? If so I guess I need to find another stretch of road for my tuning! I've seen some waves on 0 in mine, but usually not more than 20-30hp, not real sure what's considered a lot...?

 

Nevermind, just saw your post! Id say I need to tweak where I start/end my pulls. Between 1 and 10 smoothing there is a 20whp difference on the pulls I have. On 0 smooth there is only a 140whp diff in the bottom and top spike, which isn't as exaggerated as the 4th graph on that page, but obviously not optimum.

 

basically its the road and road surface in general. even a road that looks real good is sometimes bad. i ran into the same issue on my personal car.

the only place i can get an accurate reading is the interstate where the roads are real smooth and concrete.

gotta remember the surface area the runs being tested on gotta be perfect.. just like a real dyno. if the rollers had spikes on them it would make the graph jumpy.

also check tire pressure in the car, make sure that is good also.. uneven tire pressure can cause issues also.

my advice would be get it on the interstate and redo some pulls! it will be more accurate.
