Pump gas and sane levels of boost are in the future... I'm still just reminiscing of the Honda days where 9:1 was nice for a street set up... off boost torque and a slight bump in MPG.

Thanks, I may reconsider... I'm building some "cake to eat" so I'm looking at daily fuel economy too. Some will say I'm crazy, but you can get big blocks to run over 20 MPG or better with the right set up.

 

Honda has a very good combustion chamber design, but you still have to be carefull running high boost on 9:1 compression on pump gas.

 

Of course... yet it is all relative. When customers are ready, do you stock the kits, or are they ordered?

 

Evo8 stroker kits are ready to ship today! If you want custom compression or custom rods then there might be a slight wait.

Martin,

This is Lee, I bought Mike Iuro car w/ the 3076 turbo, I'm tempted by this 2.3 stroker but first some questions

The obligatory how much more power can I expect ? what will the redline be set at ? what kind of boost can I run on 92 oct pump w/ the recommended 8.5 CR ?
I imagine it would be more streetable than the current setup w/ 272/272 cam ie closer to stock in idling and low RPM driving characteristics.
How many have you guys done so far ? I would really like a ride or drive one if at all possible before making up my mind.

Last questions concern my current setup and tune w/ the AEM. I can only get 92 oct premiun here, I understand the car was tuned on 93 oct CHI gas and w/ the cold weather already here should I be concerned ? Does the boost need to be lowered ?

 

The tune should be good for 92 octane, just make sure the correct map is in there! (pump gas map). You will really like the stroker BTW. If you want you can send me some datalogs and I can see how everything looks.

What is a realistic redline for a well built stroker using a 100mm crank? I've been quoted "up to 9,000 rpm" by AMS on the phone and I've also read it posted by Buschur as well. Spinning a crank at that speed creates a mean piston speed of 30m/s. By comparison, F1 engines in the mid 90s were seeing mean piston speeds of 27m/s. I'm sure the machine work of an F1 engine is far better than that of the factory and certainly much better than that of any machine shop you'd take your parts to to have balanced and fit. It seems that a maximum sustained redline would be around 7,900 rpm yeilding a mean piston speed of 26.34m/s. How fast can you spin a stock bottom end? I seem to recall that the stock bottom end can handle 9,000 rpm (26.55m/s).

Thoughts?

I'm just wondering if it's better to have a turbo like the GT35R spool 500 rpm sooner with 2.3L or have a redline 1,000 rpm higher with a 2.0.

 

Propeller head don't forget with the stroker you will be making more power throughout that rev range with the stroker where as with the built 2 liter you will have the same, or most likely a tapering power band.

I have a 2.3 in my car and i take it to 8500 all day long. I really dont think 9k is a stretch at all.

Eric

 

Cool!

 

Thank Martin, I'll have to get someone to help me w/ the datalog I'm clueless when it comes to these things.


Eric, how much boost do you run in your car w/ premiun 93oct. gas ? I should have ask you for a ride in your car while I was up there at the shop, should give me a good indication how the Evo will feel w/ 2.3L

Will the 2.3 necessitate head work also ?

 

Eric - Yes, I am also interested in this information as well. On 93oct pump gas with your stroker kit & head full head work - when do you see full boost? Can you please list how many pounds of boost you are getting with your stroker kit & 35R at the following RPMs, again on 93oct pump gas:

2500
3500
4500

It would be helpful if you could compare it to a stock EVO. Good/slightly slower?? Also, as listed above what is the max boost on 93oct pump gas are you running - safely?

Lastly, how reliable and would this set-up be for the street. I do not want a dyno queen or track only car.

I want a fun - RELIABLE pump gas set-up, which is why I am asking about the 35R & stroker kit. I hate lag & I am trying to see if this set-up will reduce the lag on pump gas for your 35R kit.

I am looking to get 450awhp on pump gas and this seems like the best way to go for the street. Any insights here would be greatly appreicated, specifically if this set-up will not be reliable on pump gas. I want a one-time set-up that I will not constantly need to tear down & rebuild.

 

What about Pauter rods? Do you advise the use of them? I've heard that they are the best that money can buy. Have I been misled?

Thanks

 

Pauter rods are good rods, but we'd have to make sure the big end of the rod clears the bottom of the block in a stroker.

BTW the spool on a stroker with a GT35 will be slower than a stock EVO8 turbo... If you wanted stock like spool with a stroker then I'd go with the GT3071, but you will not make 450whp on pump gas. Get the GT35R, it will still spool quickly and it will make over 450whp on pump gas. I made 468whp on our 2.0L at 24psi of boost. on the 2.3L that should be no problem.

Dammit! Every time I convince myself to stick with the BR440 (3071) someone comes along and teases me with the prospect of what the GT35R will deliver with a stroker.
