Dyno run
Dyno run
Ok the vehicle was dyno'ed today its a 1995 Q45T with 85k miles on it, all stock. with 2 runs in 3'rd gear all the way to red line its pushed 238.86 hp at the rear wheels the second run was 236.34 hp.the tq was 291 and 294. now is there anything that i can do to increase that. any ideas

all depends on how deep your pockets are....as there are no cheap tricks to these cars.
For Increase HP...the following come to my mind.JWT ECU ($650) ~~~20HP gainJWT Pop Charger ($125) ~~~5 Hp gainCarbon Fiber Driveshaft ($1,400) ~~~Unknow HP gainBRM Cat Back Exhaust X-Pipe ($850?) ~~~ Unknow HP gainHeaders ($2,000???) ~~~ Unknow HP gain...but I like them
NOS System ($1,200???) Clean Intake/Throttle Body (DIYer...)Synthetic Fluids
For increase in 1/4 times you can do the following:Higher Torque Converter Stall..OEM is a variable 2,100-2,300 ($500+)JWT TCU ...moves redline up to 7,300rpms to hold out the gearing longer which improves acceleration ET's ($400)LevelTen transmission (although some may disagree @ $3,500)4.08 Rearend...from 3.54 gearing ($1,200 done right @ Unitrax or $800 for piece of $hit rearend that whines from another source)Replace your 95 transmission with a 90-93 transmission...the 1st gear is shorter in the 90-93 transmission by 7% so the acceleration times are better...2nd gear ratio are less than 1% different
I have the following:LevelTen transmission Rebuild2,400 Stall92 transmission into my 95 Q45THeaders (no pre cats)BRM Exhaust (no cats)JWT ECUJWT Pop ChargerSynthetic Fluids
I have yet to dyno the car...but will do so this fall....I got a 14.6@97mph 1/4 ET which from what I can tell is so far is one of the quickest documented ET...but I have many different mods than others who have run there cars so my car is not comparable to others.
Congrats on your great dyno numbers...I am sure Q45tech will comment on the variability of the dyno results. My suggestion would be to replace parts as they wear out with more performance oriented parts which may cost the same or a little more. It will take longer to get a nicely modded Q45...but it will be cheaper in the long run versus replacing parts that are already functioning good. For example, the OEM driveshaft usually need replacing around 110K for $900+installation, but for an extra $500, you can get the carbon fiber driveshaft and increase the performance of your car.

Just for clarifications sake, the CF driveshaft will not increase your horsepower, but it will increase RWHP as it decreases the "loss" from crank to the rear wheels.
I know it's symantics and that Rob knew what he meant, just clearing it up as we seem to have quite a few new Qmembers lately, and they might not have read the CF drivesahft thread.
Now, back to modding that Q.
Nice run BTW, be interested to get Dennis' (Q45Tech) thoughts. Do you know if the knock sensors or o2's are new? When were your plugs replaced and are they the NGK OEM spec?

thanks for the clarification Rex....
Also the 4.08 vs. 3.54 rearend will not improve nor reduce your 1/4 ET....see my experiences with both in another thread....but the 4.08 will help your 0-60 times and makes the Q a lot of fun to drive around town for some casual street racing here and there.
and as Rex said....make sure your car is properly tuned and within OEM specs before you start any mods.

Must have been a Dynojet dyno to get those EXTRA HIGH [238/236] RWHP numbers.
A Mustang dyno loaded to simulate real world conditions will show about ~~ 15-20 RWHP LESS.
The numbers suppled for RWTQ cannot be real as those are the normalized flywheel numbers.
Anyway either set of HP numbers are ok showing the engine to be ok.
The best mod based on HP dollars is the JWT ecu, the most feelable increase in 3500-7300 rpm range for dollars spent.....especially in the 50mph -100 mph range. This will add up to 20 RWHP as measured on a Dynojet.
