Went to dyno today

[four six]

251.8 RWHP 276.62 RWTQ



Maybe I was just expecting too much but I really think those #s are low. It was a dyno jet BTW. A/F was pretty good, Ill scan my sheet later

 

[Stan Weiss]

What were you expecting? The PI swap should get you to 260HP flywheel. Your cams and exhaust have gotten you to about 300HP flywheel.

This is a 98 GT remember, a 98 Cobra takes FULL BOLT-ONS(headers, full exhaust, intake, spacer, udp, tb) and dyno tune to get to 277~whp

 

[SilverBullet00]

It's had the PI swap though, so I would think it should be around 265hp and 290tq

I don't know. Like I said I just had too high of expectations

My 98 Cobra doesnt have an intake or headers and it makes 276rwhp

Has your car been dyno tuned with your current setup? I would have thought that your numbers would have been higher too.

 

[Kilgore Trout]

Are those corrected numbers? Was it really hot and dry when you did the pulls?

 

[CobraRed_96_GT]

my guess w/ those mods would have been 255hp 283 or so tq, so it's not that much off. When did you last tune it?

 

[four six]

Those are my current numbers

PI swap
VT cams
exhaust



He "tuned" it with my diablosport. All he really did was adjust the WOT fuel and check the timing.

KT yes those are corrected (SAE)

 

[RoadconeTuning]

its a little low... i would expect 270's or so... if you did the heads from a PI motor then your in the mid 10:1 compression and should have much better flow... and with a set of longtubes and a good tune should be over 300whp... whoever tuned your car needs to do a lot more work or you've got some crappy rings.

 

[98gtblue]

You need LT's!

 

[four six]

Yeah Im hoping I don't have really bad rings.

Does anyone know where I can get a mail order tune for the diablosport?

 

[four six]

You need LT's!

I know, I know but I need $$ first. Im kinda broke after all of this

 

[nesqwick_05]

dont let these numbers put u down, remember hp doesnt win races, tq does .i would be happy with those numbers if it where my car, and after all this i think you need some spray

 

[02TruBlueGt]

how you like my 4.10s man?? numbers seem aite. Also to the guy who said a 98 cobra takes full bolt ons to get 277 rwhp you got something wrong. My friends 96 cobra with lt's xpipe catbaclk (all bassani) and C&L intake make 295rwhp and 295 rwtq.

How many miles do you have on the engine???
Just contact Diablo and they will make you a custom tune.

 

[MyBloodRunsBlue]

my SAE numbers are listed 245hp/290tq with the listed mods below. you shouldn't be too disappointed those aren't shabby numbers at all for a 98 GT

 

[four six]

I LOVE them. Thank you again They help with the city driving a lot. I also went on a little road trip and they were not bad at all. 4.10s FTW

I know the #s aren't bad for JUST a PI swap but my big thing is that I have VT stage 1 cams too
