Wow !! HBP is on, installed at Comptech today

First, i don't have a scanner so i'll give you the before and after dyno #s the best i can. Also, it was 94 degrees at Dyno time So, not the best time to dyno but hey, what are you gonna do ?? At least it's apples to apples and both dynos were done on the same equipment within 2 hours and only 1 or 2 degrees difference.

When i had the car dynoed on the same dyno back in the winter, i topped out at 269HP/220TQ, it was in the upper 50s temperature wise. Today, my peak baseline was 248.9 HP/209TQ, so obviously, the extra 38 degrees was a real drag on the #s.

Here's the before and after dyno for the HBP :

2200 RPM HP - 48.2 / 51.0 TQ - 115 / 122
2400 62.3 / 64.8 136 /142
2600 76.7 / 78.1 155 / 158
2800 89.4 / 94.8 168 / 178
3000 102.9 / 109.4 180 / 191
3200 109.8 / 120.6 180 / 198
3400 119.5 / 132.3 185 / 204
3600 129.9 / 143.0 190 / 209
3800 139.9 / 152.4 193 / 211
4000 146.7 / 163.4 193 / 215
4200 158.5 / 175.1 198 / 219
4400 169.3 / 186.5 202 / 223
4600 177.7 / 195.1 203 / 223
4800 185.1 / 204.5 202 / 224
5000 196.9 / 217.8 207 / 229
5200 207.1 / 228.2 209 / 231
5400 214.1 / 237.5 208 / 231
5600 220.3 / 242.9 207 / 228
5800 225.1 / 246.7 204 / 223
6000 233.8 / 257.9 205 / 226
6200 239.7 / 263.4 203 / 223
6400 245.5 / 269.3 201 / 221
6600 248.9 / 275.2 198 / 219
6800 246.9 / 279.6 191 / 216

So, 280 HP to the wheels on a 95 degree day, and a 31 HP peak gain, not bad !! I figure that since the base dyno today was down 20 HP from the previous that if i ran it again in cooler conditions that i'd be right at 300 ( 269 previous HP plus the extra 30 or so from HBP)

It was 102 degrees when i left Comptech. I only jumped on it a couple of times, it perks up quite a bit quicker, YEEHAA !!! Can't wait for cooler weather. Oh yeah, it's running at least 95 octane and i won't go below that !!

 

Holy shit! I can't wait to get mine!

 

Wow... 300 at the wheels would be sick! That's like 400 at the crank!

 

AWESOME!!! 300HP to the wheels on an auto is AWESOME!!! If I get a B-pipe and some lighter wheels I should be right there with you. I've got a 8:30 dyno scheduled tomorrow. I've got the 19's on right now but I'll take 2 of the stock 17's so see how much power loss I get. I also want to see the difference with and without the IMRC hooked up.

Now get to the track!

 

More like 350-360.

 

25% loss = 400

 

Hey Glen, can you send/post a picture of your V1 hardwired? I never did get a chance to see how you mounted it.

Oh yeah, forgot to say - BE CAREFUL!!! Torque steer becomes a little more pronounced.

 

Yeah, now that I think of it, we do only dyno 190HP stock = 25% loss.

 

Nice #'s Glenn!! Not too far off of cls6spd's #'s. I think he dyno'd on a much cooler day too.

 

Nice!!

 

congrats, nice to see the cali peeps gettin the hbp

hit the track up

 

What should a 300 whp CL-S run in the 1/4?

Given a good 2.1 or 2.2 launch

 

13.3@105, seems very possible, flint ran 13.6 on heavy 19's

red riders car is very capable of very low 13's with the right prep and driver, with the hbp i'd run straight 100 octane w/ no chaser at the track

 

correct me if i'm worng but isnt there a correction factor for temps, so it doesnt really matter what the temp is when u dyno

 

Hmm... i wonder what a little eManage would do...

 

Nah shouldn't be. If the engine has a higher IAT it won't make as much power.

 

Very impressive numbers, given the conditions!

 

15whp at the least, once u add f/i there are no limits!!!

 

Congrats

Wow. I didn't think that the HBP would add that much more HP. The 31hp is almost a 12.5% increase. That's pretty significant. Good going Glenn

 

the hbp really needs the higher octane, so it makes a bigger difference when you have it on with about 95. if he were to put regular 91 in, that % increase would go down.
however, those numbers are excellent and i would be very proud if i could pull off similar. btw, can you give us some other little details such as: what kind of dyno? and did you have the 95 mix in the baseline runs with the stock pulley?

 

if you can post the dynos that would be great too, i can use yours for comparison as your setup is close to mine.

 

Good PAWA
Enjoy!

 

those are great #'s. you need to take it to the track quickly. time for me to rethink my next mod. humm, supercharger or bottle????? so hard to decide.

 

I dont know if I agree that the tranny always eats up 25% power even when more hp is being produced. Ltes agree that stock the tranny steals 60hp, so add 60hp to his whp and you get ~350hp at the crank (i'll split the difference between his 280whp dyno and the estimated 300whp @ cooler temps). If the car actually had 400hp it would trap close to 110mph pretty easily, which no SC car has done to my knowledge.

 

he should trap 105 on a good run.

 

Drivetrain loss is measured by a percentage, not by a number. Increasing 60 at the crank doesn't mean 60 at the wheels. No offense, but your theory doesn't make sense.

If you lost 25% while you were stock, you will lose 25% even with a S/C. He hasn't made any improvements to the drivetrain to make it more efficient; he's just added power.

 

Glad to hear the success. I know you will enjoy that extra power.

 

See Glenn i told ya.

Awesome man.

 

Thanks everyone !!

I will take it to the track in November when temps are cooler, maybe MATTG will come down from PDX and test drive for me

 

I'm glad i did the dynos before and after, we were all wondering what it made and now we know. It's funny, cause a few people said that the HBP gave the car as much Butt HP as adding the SC did !! I guess they were right

I hope your dyno comes in where you expect, what are the temps up there today ? Good luck Bro !! I'll be looking for details tonight !!

 

The way i figured 300 at the wheels comes out to about 384 at the crank. Our dynos stock average 198-208 so i figured 203 average divided into 260 = 78.07. 300 divided into 384 = 78.12.

 

I'll see what i can do on the V1, would you PM to remind me, thanks.

I gave it more of a test this morning, it definitely kicks ass, it was only 68 degrees !!

 

Yeah they looked at his dyno and it was May and in the 70s.

 

I topped off with 100 last night to increase the %. Comptech advised me to run more octane. The nice thing is where i have started to buy the 100, last night she said they would give me a discount so at least it came down from $6 a gallon to $5.40. I'll probably run 60/40 100 to 91 octane. What the hell

 

They told me that the 95 degrees was gonna be a big factor, it was a Dynamax. The important thing was doing both within a couple of hours so i could see what difference the HBP meant. As Arnold once said " I'll be back "

 

Dynamax.

Yeah, the 95 mix was in for both runs. Truly apples to apples as they say.

 

I'll ask Hammerman to post the dynos for me. He'll be back from Hawaii tomorrow.

 

The bottle is great for those quick bursts, MATTG showed us that

The SC is great for having lot's of power ALL the time. Maybe you should do both

 

Thanks Steve, time to talk IC

 

You were right
