Ok, well last year around this time on a mustang dyno I put down 241/228 with just a stage 2 and K&N intake. Do you think I could put down (on that same dyno same time of the year) around 270-275?

Since I dynoed 241, I have added the following:

2.9 pulley
zzp midlength combo (1.75 primaries / 2.5 dp with high flow cat)
Custom 2.5 magnaflow exhaust

Seems far fetched...but breaking down expected gains from each of the mods, I guess it seems logical to me (definitely a noob)

Also, would I dyno more with a heat exhanger or would I just hit full boost faster?

 

no....

 

Not even close

 

You wont lose as much gains on the top end of your run with the heat exchanger because you wont get as heat soaked. It wont help you boost faster, that is the pulley. No you wont hit 270.

 

Are you on the Stage 2 tune? If you are I see 250-255

If you are tuned I can see another 10 or so!

 

easily 250.. but i dont think theres anyway ur goin to get 270.

 

ok, first off, who cares what you put down for numbers? You should be more worried about what kind of gain you get from those mods.

I would hope you gain about 20 horses from those mods, at least. So I'm gonna guess you lay down 261 and 243, that would give you +20whp and +15wtq which is a pretty good gain for those mods. With a tune, I could see as much as +30whp and +20wtq putting you at 271 and 248.

 

Get custom tuned.

 

only one way to find out...get dynoed.. dont get your hopes up dont expect a certain kind of number

 

have them tune it while its on the dyno...duh...lol

 

i made 265whp with my set up, but with 2.9 and 42s I dont think so.

 

I put down 262/ 243 on a 2.85, full exhaust, intake, custom tune!

 

i put down 227whp on gm s2 tune and all the mods you have but with an cobra h/e

 

i got 263 with a full 3" exhaust, Intake, 2.9 and 60's, Dyno Tune

 

add some meth and get tuned for it, 60s lbers, 2.8, with your full exhuast youll hit 270

 

if ur goin to run meth just go 2.7

 

haha be dumb like my cars prevous owner was an get a 2.6 with no cooling mods haha!!!!!!! jk dont go smaller 2.8 i think. o gl hittin your mark

 

i have a 2.6 right now with a big front mount, i think im just creating mroe heat than boost that i benefit from. im gonna switch to a 2.8 with some meth, yet tuned for performance as well

 

250??? I know I asked for advice but I think that is wrong. I mean, I understand I asked. But think about it. My previous dyno (on this dyno and this time of year with stage 2 and k&N was 241).

2.9 pulley (? whp)
ZZP combo (rated 15-40 hp depending on mod level)
Catback exhaust (5-10 hp?)

I understand that hp doesn't simply "add", but you are saying that those 3 additions will give me 9 hp "at the most"????? I apparently know less than I thought

 

every car is different, do it and find out how much you get

 

ricer math FTL, look at what everyone else is getting with similar mods plenty of people have posted up there results. Don't ask what it could gain, then nah say when everyone tells you different. Do it, see what kind of # your car puts down, and go from there

 

TROOF... every car reacts differently to mods.... I would give you 255-260 but 270 takes a lot of tuning to get it!

 

he has a point

 

Is there something wrong or ricer about me not understanding why a header, downpipe, catback exhaust, and a smaller pulley would only give me 9 hp? Wanted to know if there was a method to anyone's opinions. One guy said he dynoed 227 with my mods....Well I dynoed 241 w/o most of my mods so that obviously suggests that every car is different.
But ricer????really? keep the gloves up...

 

Dood, chill! But that is the lingo man... Ricer math when you base everything on estimated power numbers!

If that were the case I'd be well over 300 whp but i'm not!
