Dyno Predictions?

[turbocody]

i will be going to the dyno on saturday and i was wondering what numbers to expect at 23-24psi? i dynoed 316hp and 456tq when i had the stock turbo.the only thing i have changed since then is a Ta-49, Boost Controller, LT-1 valve springs, JL 104 race chip(23*), all RJC Aluminum pulleys,and 50# injectors. so what kind of #'s are we talking here. temp will probably be around 90*. thanks

 

[TurboShane]

about 360 that's my guess. Let us know.

 

[FastRegalWE2]

I'll second that, 360-375

 

[turbocody]

any torque #'s?

 

[BLACK6PACK]

If you push it, 400 hp and 500 tq, but with just a 104 chip Ill say 375 and 475tq.

 

[turbocody]

well, i guess i will shoot for 375hp and 475tq, i want to run 25psi of boost, is that ok for the 49 if i don't get any knock? i have been 23-24psi with no knock so i guess my question is if i turn it up to 25psi will it start to blow hot are and go downhill??? i'm going in the mornings so some quick answers are greatly appreciated.

Funny, I'm going to the dyno this Saturday as well. I have nearly identical combo as you. I'm going to be running pump gas and alky with the TA49 set at 24lbs of boost. I'm hoping for 400HP/500TQ. I think I'll hit the torque but be a little shy of the HP. We'll have to post our results and compare.

Should be fun.

I just went to the dyno a few weeks ago. 413 RWHP, 570 ft/lb TQ.

Geoff is that the same tune that got you the times in your sig??

I'm hoping to dyno my soon.

Jeremy - I drove to the track later that night. I did however, have to run a bit fatter (richer) at the track since my EGT showed that I was running lean.
The timeslip in my sig was from that night; -the only full pass that I made, and the last one of the night. I had another problem right before the 1/8 on a bunch of other aborted passes. Still unsure of the cause............

Needless to say that I was given a warning from the track official right after the last run.

 

[Nocooler]

Wow, makes me wonder what I put to the tires with my Ta49 trapping @ 117mph.

BTW - with the new NHRA rules - my track doesn't seem to care with me clicking off mutiple high 11's in a night.

well i got it Dynoed. it made 380Hp and 523Tq at 24psi and 23* of timing on 104 unleaded with 0 knock. i did not lock up the converter but i guess it was worth 20hp and 20-30tq i think but oh well, i'm happy with those numbers since it was 95* and 60%humidity you should have seen the look that one of the dyno guys made after my run maybe next time when i go when it's better weather, i will turn it up to 26-27psi and shoot for 580Tq thanks for the predictions. you guys were right on!

 

[TurboSlacker]

Similar results for me yesterday. 363HP/549TQ. Converter not locked-up and 92 pump gas w/ alky. And was while experiencing erratic ignition drop outs. My best numbers of the day started recording after my peak rpm.

I would like to see closer to 400HP and 575TQ but no complaints here either.

Maybe after fixing my ignition issues, I might take it back to the dyno to verify the problem is solved and get a few more pulls.

Great numbers guys. How much did it cost to dyno and how many runs did you make? I want to dyno mine soon. Since you guys came so close to guessing their combo numbers how about taking a stab at mine? I have a 14" K&N, TE-63-1, ESP f/m, power plate, SMC single nozzle alky, ported heads with bigger valves, .030 over with forged pistons, 206/206 Comp Cams, ATR 3" terry-style downpipe, 3" hi-flo cat, 3" single shot, Walbro 307, 009s and a 20 degree street chip and K-B hot flash chip. I have the usual stuff like adj. regulator, Scanmaster and K-B boost-a-pump to push more fuel. I'll push as much boost as the injectors can handle with the street chip but only around 18-20 with the hot flash chip. I'll be getting a Turbotweak chip soon but not sure if it will be here before getting dynoed. Any guesses? This won't be a track car, just my daily driver. I am just curious as to what kind of power it can have with a good tune.

I ran on a DynoJet. 3 pulls for $65. A great deal compared to the typical price of $75-$100. Some the other Turbo Buick guys that came out even ran up to 6 pulls trying to work out tuning issues and they still only charged them $65. Fortunate to have a cool dyno shop near us.
