hi all, first thanks to OZ for all the predyno info. This am I took my 2010 xfr that has a eurotoys, lower/upper pulley and tune. center section removed with x pipe and mina axle back. I can tell you all looking at input from so many on this site had me scared to go to the dyno as many say the mods i have aren't worth much. Well I took it to latemodelthottle in Waukesha Wisconsin and Jeff put me on his dyno jet dyno. HP 539.24 at 5900 and 573.71 at 3500. This was after a hour drive and 20 minute cool down as I didn't have an appointment. We shut it down talked for about 15 minutes and ran it again 538.97 and 567.30. I will put the dynoi sheet up when I have a few minutes to figure out how to do it.

I have to say the dyno supported my seat of the pants feel and was happy as I could be. Look forward to the next rounds of mods right now I have 25K in the car including purchase.
lmk what you think

so what I learned today these cars can be beasts with very little modifications ones that don't cost alot, if about 120 rwhp isn't worth $2500ish I don't know what to tell ya


eurotoys and Mike Werner have my strongest support as a vender
jeff at latemodethrottle is the place to get a dyno run if ur within a hour or two of his shop
these folks have always been willing to help a guy who knows little about power added cars

 

That looks really Good! Not much power loss at all between runs.

 

Yep, great results!
Nice AFRs as well, as expected started to drop (get richer) after around 5,300 rpm but not too much.

 

oz if this was ur car what would your next mods be? I plan to have eurotoys put the upgrade charge cooler and bosch pump along with the timing set llikely the coolant pipe that is always a problem and a solid coupler.

have new prop shaft and all the fluids changed

 

Yep those mods are what I would do as well. If you want a bit more power and much better (lower) IATs then I suggest you look into water/meth injection, a few have done this on their F-Types with good results.
On a 2010 XFR you will have the alloy upper coolant pipe (cross-over pipe) as opposed to the later crappy plastic seam welded one and they rarely if ever leak, dunno about the lower coolant Y pipe so maybe replace that one, and replace the SC coupler. While you are in there replace the SC oil and consider replacing the SC bearings, you can get coupler, bearings and oil kits from Powerhouse. Replace the coolant manifold pipe as well (the cross-over pipe at the back under the SC).

 

the guy that dynoed it said I should have the supercharger rebuild and ported, he said that supercharger he has seen 40-80 whp from a guy not far away at jokerz performance mike thought injectors, maybe fuel pump.

I would like to get to 600 rwhp if I could without spending a ton

 

Interesting as I have been in contact with Brett at Jokerz about porting my XJ blower. I have not sent it in as I am waiting to bundle a couple of items together to make it worthwhile to pull the blower. He quoted me 30-50 HP and about $1450+ for cost. But I only have the lower pulley as VAP has warned me about adding the upper due to heat soak.
Take a look !
Blower Porting

No idea where you can get bigger injectors either?
Same with upgraded fuel pumps?
Might have to adapt something from a different car?

PS; They port the TB but has anyone added a bigger TB?
