In the interest of conducting research for our LNF turbo upgrade, we installed a ZZP turbo manifold in place of the stock manifold and bolted up a Bullseye Power S256 extended tip turbo. It is basically the same as our twincharge turbo, except for a smaller exhaust housing. We quickly got into the 370whp range, but then we began battling the ECM and all of it's abilities to veto anything radical. We hit 390whp on 93 octane, but ended up putting in some 110 because we figured we'd be making a lot of pulls and didn't want to risk a 4k mile LNF motor this early in the game for us. Many pulls later, we surpassed 400 with a clean 403WHP at 24psi. FWIW, this was done with the factory airbox with a custom short ram intake tube, drop-in K&N, and inlet tube mod.

We will be racing this car soon, but I'm afraid that I'm going to have a lot of difficulty getting down the track. The boost hits way too hard to feather the throttle for moderate power. I'm hoping to set up a multi-stage or progressive boost controller to keep the tires from going up in smoke until half-track.

Any guesses what times/mph it will run? Keep in mind that I have very little experience drag racing a manual trans car. I also won't have the luxury of having 28" tall slicks and wheelie bars like I do on the Grand Prix. I might not do so well the first time out.

 

14.xx@ 118ish

 

Either way, that's awesome! Keep up the good work.

Do you have a dyno sheet for us to look at?

 

rite........i'm thinkin more like 12.xx@115-125

 

I think he spins through 3rd.

Maybe 13s

 

12.7 at 118

 

i say 13.2-13.5 @ 115+

good driver def 12.8

 

since my friend has a 400hp civic and getting in the 11's im thinking 11.xx if he can put the power to the track instead of up in smoke.

 

12.8, 120mph.

 

12.5 @ 122

Ending the race close to redline in 4th

 

lets see your dyno graph

 

wow. 400 ponies under the hood with very few mods... i have turbo envy. good work guys.

 

at 320 whp with no traction i ran a 13.4 @ 116mph

 

With that turbo and tuning the redline should be raised.


Probably revving it out to 7200

 

24psi?

using a map clamp?

nice numbers

got any graphs with stock over lay

 

11's should be there!! come on

 

We were dynoing up to 107 in 3rd, so 4ths redline should be in the 130s.

Regulators. What we really need is more PCM access so we can alter the MAF delta limits. Every time this turbo hits hard it closes the throttle instantly. We have to bring in boost progressively. It works, but the torque numbers are only in the 360-380 range when we do this, depending on how quick we bring in the boost. When we let the turbo hit, torque was over 400 just before shutting down.

I'll get some dyno graphs printed today.

 

11s with dr

 

I think that will take better tires.

 

This car sounds like a beast. Vids or graphs would be nice.

 

12.3 @ 124....... do i get anything if i win?


like...... i dunno...... the turbo kit?

 

I say 12.5 at 120mph

 

thats what i was thinking...ishhh

 

you better be looking at full out drag slicks

 

I was thinking the same.
