Ok so wondering what kinda of numbers my budget build gsr will make here soon. Everything done and runs smooth way better on a chipped p72 running 92 but wondering what the tune and dyno numbers will make???

Gsr head
Gsr mani with mild port and polish
dual valve springs I&E gsr's
GSR cams(trying to find itr's before tune)
stock valves and redone seals
Arp head studs
stock head gasket
Greddy header with 3in straight pipe (ment for turbo but its all i have for now)

Gsr block
81mm PR3 pistons
Gsr Rods with arp rod bolts
balenced to 9k

planning on reving to 8.5k with or without itr cams. Anybody tell me what numbers i might make???

 

+180hp imo..

 

What dyno are you going to dyno on? Street tune or dyno tuned? What Engine management? Gsr mani with or without Butterfly valves? etc.

 

Dyno it and figure it out. Stupid post.

 

This car might make 160.

 

Chipped ecu?? Chipped for what mods? The only one that can accurately tell you what you are going to make is a dyno

 

x2. Its a stock motor for the most part. MAYBE upper 160's on a dynapak

 

There is a lot of factors to involve when talking about dyno numbers. You are missing a lot of info to really give you a some what accurate guess.

The bigger factors that you are missing are the proper EMS you will be running and what dyno... I always run on a dynojet (most accurate IMO) because of how accurate the correction factor is.

For the most part I will agree with everyone else and say maybe high 160s or low 170s if you have good stand alone (S300 or some type of AEM) and if you have the ITR cams with a good tuner who knows what they are doing.

Also as a side note, don't get caught up in the numbers game. Doesn't mean S**T.... Use it as a reference rather than a make or break factor.
