Dyno'd Crvtec Today
 

Today I finally had time to dyno my car, yesterday it sat at the track like a little bitch in the corner that stored coolers & food. ::)

sad sad....

As expected, I hit my goal, a tad over 300whp. 306whp / 228tq running 12psi on pump gas.

It took 18 passes on the dyno to get this fucker tuned, Nick lopez helped me out working with my fuel map, it took almost 15% more fuel than the LS/vtec map I had made. I'm a bit worried my dsm injectors are about out of juice ;)

Overall, I'm really happy, the car ------- rips incredibly hard. Traction... well there is none. The lag of the .63 housing is nice, but I still need a bigger compressor IMO. The spark map is very friendly, so not worried about detonation, also installed my walbro 255 back in.

I dont think I'm gonna drag this car again, maybe.. My goals are almost done 12sec/300whp daily driver, and a 10sec/400hp race car.

18 runs? Good lord. :o At least it is all tuned in now. You need to make at least one pass to see if it can actually run a 12 :P.

he ran a 12.7 on the LSVTEC...

Re:Dyno'd Crvtec Today
 

----, nice dude.

You HAVE TO atleast run it 1 time down the track..

Re:Dyno'd Crvtec Today
 

I don't see the difference between the ls and crv tech numbers.
What rpm does that .63 kick in at?
Overall, I like. :)

Re:Dyno'd Crvtec Today
 

You dont see the difference?

lets take a closer look... ;D


https://www.homemadeturbo.com/turbo/b20/b20dyno.jpg
306whp / 228tq (12psi) B20 .63ar

https://www.homemadeturbo.com/ride/89si2/dyno.jpg
263whp / 201tq (12psi) B18 .48ar

The turbo definatly takes a tad longer to spool, but I think I could use a new compressor.

Re:Dyno'd Crvtec Today
 

ya looks like it falls off near the top.

Re:Dyno'd Crvtec Today
 

What about the hp vs. costs difference of an ls block and the crv? I thought the crv blocks were expensive these days. Just wondering

Re:Dyno'd Crvtec Today
 

hehe, its fun having that much hp isnt it :) now you just need a little more torque....

looks good man, put some race gas in and run it..

Re:Dyno'd Crvtec Today
 

Nice, that's awsome for a daily driver. I really need to get a CRX.

Re:Dyno'd Crvtec Today
 

congrats !!!!!!!!!! jeff......im right behind u.lol. i got my post screws from eldyn so hopefully by doing it right and a little more boost ill reach the 300 mark .......keep updating us on ur progress ;)

Re:Dyno'd Crvtec Today
 

you now you will come out and play.. you dont got to lie to kick it.

Re:Dyno'd Crvtec Today
 

pluse its just a hunduh not a dsm ;D

Re:Dyno'd Crvtec Today
 

Congratz Abaz. Those are some impressive numbers. You gotta take me for a tire smokeing ride. ;D

Re:Dyno'd Crvtec Today
 

Is there a difference on the motor if you drag the car at the track compared to at the street races?!?!?! It's the same 1/4 mile isn't it??? I'm confused!!!! :P lol

Re:Dyno'd Crvtec Today
 

what i was thinkin.... 8)

Re:Dyno'd Crvtec Today
 

Time for nitrous?

Re:Dyno'd Crvtec Today
 

ok so you made 268 with a 1.8
and 306 with a 1.97 (b20 is not a true 2.0l for those that dont know)

this is my plan true 2.0l b16a by bore, because the rod/stroke ratio and the short stroke I think myght serve well on a 2.0 litre block. which may make more than 300whp.

but hey I am a stupid ass so I could be wrong.

but for instance my friend thang who owns a local shop over here has his 9 second b16a powered crx, has his b16 bored to 2.0l (85mm on a b16a) and he made over 650 hp on the first run. the only reason that he has only ran a 9 is because he has stupid little problems with the car.

ok I go

Re:Dyno'd Crvtec Today
 

Thats like saying a GSR isnt a true 1.8L who the ---- cares?

I thought you were banned pizza boy..

Re:Dyno'd Crvtec Today
 

and a d16 isnt 1.6, its actually 1595 ;) (or about that, I know its LESS then 1600!!)

Either way, Jeff, propz, very nice dyno chart, ,I am SOOO jealous ;)

But I think you are right about your injectors. With a .63 it should be climbing still at red line. Time for some 720cc's huh!!

Re:Dyno'd Crvtec Today
 

we could never be that lucky. pizza face, shut up, you aint doing ----. you just came on this thread and posted something that you prolly just learned 2 minutes ago, and you impressed yourself, but we don't care. oh yeah, mad props on the crvtec jeff, those are impressive numbers, did you put you lsd in there, or do you not have it yet?

Re:Dyno'd Crvtec Today
 

1.97 IS 2 liters. .03 doesn't matter

Re:Dyno'd Crvtec Today
 

I'm assuming you wre running open exhaust straight from the downpipe. Good numbers.

Re:Dyno'd Crvtec Today
 

what can a ZC be bored out to?

Re:Dyno'd Crvtec Today
 

Not much

Re:Dyno'd Crvtec Today
 

Full 3in exhaust was used at the dyno.

and 77mm bore is about as large as you can go on a D-series, But its really pushing it.

Jeff

Re:Dyno'd Crvtec Today
 

i just bought some new top secret parts that should put me in the high 300hp range :) :) :)

Re:Dyno'd Crvtec Today
 

Jeff.... I'm a little bit... yeah, Jelous of that :'(

But good Job!!! ;D

and yeah, that's an awesome difference in power... Can I ask that you not take it any higher than 12-13 psi ???

Re:Dyno'd Crvtec Today
 

naaaawwzz ? hahah

Re:Dyno'd Crvtec Today
