on some wonder dyno sure, on a dynojet, there hasn't been anyone that broke in the 300's yet. the figure seems to be in the 290's... but then again, i don't think there was a full bolt on hr on a dynojet either. but i can pretty much tell you right now it won't be as high as 318...

 

Have you been living under a rock?

i can think of 2 people right now!

 

who?

 

A.H.(Arsh)

and this guy=

And there both Automatics.....

makes you want to change your signature doesnt it!!!

 

Neither Arsh nor the youtube guy did there runs on dynojets....

I have all the breathing mods they do, and i dyno'd at 262whp up here in the Mile High City....

At sea level, on a not so friendly dyno, 290's sounds about right....

 

No........A.H car is a myth until it runs on another dyno and/or at the track. If it pulls the same numbers sae on a dynojet or traps 110-112, I will be more than happy to go back and delete any derogatory comments towards his car. The second vid was on the same dyno. So no, still no 300's on a "non magical" dyno. I really hope someone does and I do believe it is more than possible.

Don't go and dig up all those crazy numbers from the one shop in NY either. Lakeside made 26X and with the same mods put down 30X on that dyno.

 

dual CAIs
test pipes
true dual exhaust
uprev tune

i'd leave it alone after a while after those 4 things, but if you want more you could go crazy with an N/A build:

clutch/flywheel
headers
high compression pistons
rods
cams + valve work (springs etc)
head work

would be very expensive but pretty cool when its all done.

 

like stated above, A.H didn't dyno on a dynojet. I'm not talking down A.H one bit. he did alot for hr owners. his peak number may be off, but he still tested all the bolt on parts and found out for us which parts make power and which don't.

there are 2 local hr's with all bolt on's minus headers (one just ordered headers). one with a technosquare reflash, and one with a cobb tune. both dynoed in the low 290's on a dynojet. according to A.H's test, headers are worth about 5 whp peak (more throughout the rest of the rev range) on a generous dyno. my best edumacated guess is that peak dynojet whp for a bolt on (with whats available now) hr is just under 300whp, maybe barely breaking the mark...


ps. if you know of a z that did more than 300 on a DYNOJET, lets see it

 

Added the bold.

I agree. I think it will be pretty exciting to see someone do an actual build of an HR.

 

^thanks for the addition, i should have mentioned that

although come to think of it, i don't think i've seen over 300 STD correction either...

 

^^^ word
with a N/A build of 10k, i'm sure it could be possible to get 330ish to the wheels on an honest dyno. put some spray on it on top of that, and you have such an adrenaline rush at WOT....

it would be cool for some people to state possible ideas of their own future build on their HR. (not including CAI's, Headers, Test Pipes/HFC's, Exhaust, Dynotune(we all know this is a must lol)

 

well since you're asking, power wise mine will stay the way it is right now (motordyne y pipe and fujitsubo exhaust) till / if sasha makes longtube headers for it. then i'll prolly get those. if those never get make, i'll prolly add hi flow cats or test pipes eventually, and an uprev tune to match whatever i get. shorter final drive and lsd are the next mods for me. then more suspension stuff...

 

^thats fair, i'm sure you'll be happy with your results

 

so this might be a silly question but does it do any good to swap out ur exhaust to a catback, and swap out for an intake and test pipes if u leave the stock headers on? I mean will they be restrictive or do the headers not really make a difference?

For example if ur gearing up for an N/A or FI build and aren't sure which yet? I'm assuming u need increased airflow for either which made me wonder about the headers and if they would be restrictive or not

 

you'd be fine keeping the stock headers. according to A.H, they're worth about 10 whp through out the rev range and about 5 peak. i don't know of anyone else that has a before and after dyno with them on an hr engine...

 

headers aren't really worth the trouble. i got them on my car, i did hear and feel a difference, but it's not worth the install

 

really only worth it to do when you're getting your motor pulled for whatever reason.

 

Over 300 doubtful with just those mods. And he has a manual not a auto.

 

318rwhp will not happen. Over 300 will not happen. Look at my numbers on a DynoJet tuned by UPREV themselves.

 

Yep and both those dynos you take with a grain of salt as they aren't with a Dynojet. Mine was. And I have the same or better mods than they do. I might be able to get a little bit more out of mine by going Test Pipes, but that's about it. Mine is a full bolt on HR and look at my sig for the numbers in 100+ degree heat it was tuned and got heat soaked quick.
