To stroke or not to stroke....

 

Are you stroked? If so what kind of hp are you throwing down? In the process of stroking the engine right now and looking for a good turbo to throw on...

 

I run a HTA 3586R with a 2.3 liter, numbers should be coming soon!!!

 

Nice, I'll be interested to see what kind of numbers you pull. Let me know...

 

Great info!!!!!..


Ps im looking for a 03 T-case

 

stroke it dont beat it!! but good info

 

I had my eclipse stroked. it was nice on the street with a 50 trim, but if I were to do it again I would of done a built 2.0

 

Stroke it brooooooooooooo

 

I bought my Evo with a 2.3L and bb 50 trim. If you are going stroker, don't waste your time on anything smaller than a 54 lb/min turbo. I personally will upgrade to at least 65 lb/min. This 50 trim with .63 housing makes 356 tq at 4700 and 351 hp at 5700 on a mustang dyno. HP drops to 320 at 7200. The car has stock head with HKS 264/272 cams. The turbo just can't keep up with the 2.3 and you can feel it.

 

4g64 2.5l strocker

 

great info

 

very informative.

 

stroke it 2.3L rocks

 

Old thread found while searching I know, but for the sake of the archives... Nitrous definitely does help spool. I agree with your reasoning above for increases in CR, but remember that nitrous is more air and more fuel burned at that same rpm, which results in more exhaust product, which results in a lower boost threshold. It's the same thing as increasing displacement, more exhaust product per rpm level. In fact I think one could make the arguement that if you add 20% of your power with nitrous the effect on boost threshold is the same as a 20% increase in displacement. I used this theory to calculate the increase in fuel requirements with a dry system on my car and it worked out to within the accuracy of my horsepower measurement at low rpm.

On the automatic the benfit is two fold since the added torque also gets you higher up on the converter making more boost, but that conversion is unlikely to interest anyone here.

 

has anyone de-stroked an engine? Like with the principals of a formula 1 racecar? make the pistons not move far at all, but move a lot? seems like you would rev REALLY high that way and make good power and torque? i might be way wrong, just seemed cool and didnt know if anyone had done it or even looked in to it
