what sthe approximate range of HP for Spec boxster motors?
obviously i know it varies from car to car, and from dyno to dyno.

but whats the range for a leading car? 185, 188ish, 190+?

I won the SB title in 08' with 162 rwhp on a Dyno Dynamics machine. My competitors were up to 182 that same day. We dyno'd several at T-hill last Nov. on a Dynojet w/SAE correction and had 2 of them at 186, 2 at 197, and one over 200.....

Over 200 RWHP on a stock 2.5L ? Hard to believe.

Agreed but since he was a newby and running TT's only we let him go-for now. I did DQ one of the 197 cars as his A/F ratios were flat-lined thruout the range at 12. The other SB's all went up and down, but this particular car was different....

Mine has 294 at the crank now,....hehehe.

Same as JR, I have seen mid 165'ish, to low 190ish.
From my experience I would believe the 185-190 cars to be well prepared and still within the current Spec Boxster rule set, past that you do start seeing the A/F ratios really working, well, let's just say a little outside of what would normally be seen on cars that are known to be stock.
I've seen a few also with the hp in the mid 180's but with better tq curves and different A/F ratios to match. It's not really rocket science if you know what you are doing, it's not really rocket science to figure out the cheaters either.

Our spec boxster makes 191 give or take 1hp on a dynojet, SAE smoothing 3.

hey guys.

this is so paralleling my experience with the Spec E30 guys... a 'really stock' (like straight off the street with say 100k miles on it) 2.5 E30 motor will put down low 140s at the wheels on a dynojet (assuming healthy). a 'decent rebuilt fresh normal' E30 motor will do high 140s low 150s. a 'pro shop rebuilt E30 with all the legal secret things done to it' will do high 150s low 160s. and when dynoed, the A/Fs definitely are not perfect by any means, on any of those. if you dyno one and it is mid high 160s it'll prob have a 'perfect' A/F (been chipped or reflashed or whatever).

for a while when that was going on, sometimes before the race there would be a meeting and everyone would bring up their ECUs and have to do a random swap. that was an effective way of stopping the 'chip madness'.

typically the top cars (like at the Nationals) were all pretty close in the high 150s/very low 160s. I believe they all had pro motors in them, in varying states of 'freshness'.

once Spec Box really gets up and rolling and super competitive, you guys will have to start instituting some sort of system to make sure cars are compliant. a 5whp difference in Spec E30 is fairly large; what you guys were seeing so far in Spec Box i'd consider huge. once you have 8-10 very good, very close drivers a hp diff of 10 whp will make it almost impossible to overcome.

No, not really, its easy to get the computer to do what you want when you send it the signals it wants to see, then the stock box will do just fine regardless of whose you swap it with. Many other ways to make power outside of the box as well.

Keep working on it. My 3.4 put out 315 @7500 rpms hehehe.

yeah, seems like from all the reviewing and discussions ive had with some of the top guys in top cars, looks like 185 to 190 is a sweet spot for a leading car. obviously driver talent is huge, but im just saying, drivers ideally being equal, seems like the top echelon of cars are high 80s, 90,91 ,92

TIM COSTA

Anyone have dyno #s for their car using a DynoPak??

Werkstatt

Tim, are you still running that 207 HP Spec Boxster?
