He dynoed @ the wheels & made 700 HP @ 6500 RPM w/only 7 PSI of boost pressure..
His engine is designed to go to 9000 RPM.
Normally aspirated (no turbo) car made 411 HP @ 6500 @ the wheels..
Very impressive!!! Douglas.Sorry Douglas,,,I had to give some updates before you,,,but I could not wait. I tried asking you when I IM you,,but I think you fell asleep. MBHD

wow! how many psi does he think he will need? 7 psi really woke it up. 14 may break it. hope not. when is douglas going to run it down the 1/4?
sure wish we had more specs on his motor. cam- lift /duration /type compression fuel type.

700 HP at 6500 with 7PSI, is serious! What is it, a good NA engine at sea level is 85% efficient? If I could make my 292 work here like a 100% sea level engine I'd feel great! A few psi is all you need, but a few more..........

Specs on cam are big,solid roller,,Approx 255-260 degress duration @ .050 .700 lift,115 lobe center or there abouts IIRC? He is planning on running 30-35 psi. 8.5 to 1 compression. Fuel type is methanol. The engine is a 250 L6 w/a Kirby/Sissell 12 port head. The engine is not built to run normally aspirated,he just did the normally aspirated runs to do baseline tunning & make sure there are no other problems before he put the turbo on. He hopes to make 1100-1400 HP to the wheels. He ran it in the 1/4 mile but had problems w/the converter not stalling high enough. I am pretty sure when he has time to post some more news & pics here ,he will,,,he better! MBHD

MBHD A bit more boost should fix that. Best of luck to him with it, truly amazing what they are getting out of them at that lattitude.

His car ran 15.2 @ 130 MPH with the boost still only @ 7 psi.
Once he gets the turbo to spool up & make boost on the initial launch,,,,whatch out!!
He might break the record now in Brazil of 8.4 seconds w/just the 700 HP.
The guy that set the record,,his car makes 1000 HP.
Should be interesting to see it run good.

from the vids, it looks as though he has abit more tuning to do. no surprise to me. once he gets the tune ironed out then he will have the cat by the tail. tom

I gave a few tips on hopefully to get the turbo to spool up tunning wise. We will hopefully see it set all new records.
He really put in a lot of time,effort & not to mention money into his really nice looking car.

Another pre update. Tomorrow 7-12-09,,, Douglas told me he is going to the race track.
He said he will be running 20-22 psi of boost pressure. He estimates it will me making over 1000 HP.
Hope all goes well!
GO DOUGLAS!

OK, here's the update,he ran two passes with the nitrous (only used to spool up turbo,meaning launch only) 1st,10.15 2nd 9.0 @ 155 MPH 243 KPM,,no time requested http://www.youtube.com/watch?v=95Jk6jw345k1.3 60 ft time. Launched @ only 4800 rpm & 7 psi of boost pressure ran 14 psi up until it reached 7000 rpm in 2nd & he saw 26 PSi,so he let off. He said he needs to look into why it did that. But he said it is scary fast & during the passes he only saw 35-45% TPS,he is getting used to the car still. He was the limiting factor as why it was only seeing 35-45% ,,, his foot. LOL. It has a lot more potential. Way to go Douglas,!!! Keep it up!!! MBHD

Thanks guys!! We finally ran the car launching like we want! The car runs straight as an arrow... I´m really happy! I´m just a little scared about how the car keep pushing on all rpm ranges. It seems that the engine have NO END!!! We are not revving what the cam needs yet, but we are upgrading the power level as I´m getting used with the car... It´s like I´m racing for the first time!!! Next step, we´ll see what was the problem with that 26PSI boost at 2nd gear, and we´ll try to get more boost on the launching. The goal is a 1.1 60ft time... Here is some more videos of the testing day: First Burnout: http://www.youtube.com/watch?v=nC2ZKgJJcb8&feature=channel_pageFirst 10.15s pass: http://www.youtube.com/watch?v=ek7wCI9wEJo&feature=channelSecond Burnout: http://www.youtube.com/watch?v=uqfscY9192c&feature=channelTalk to you later, guys... Hope you like it!! Douglas Carbonera - Brazil

Well,,, it is a complete tube chassis car ,that weighs approx 2400 LBS,maybe less. His orange Opala weighs 2000 LBS
He is looking to make 1400 + HP.

It is all in good fun! I think a honest goal for us is 8.80-8.90 @ 3000 lbs. That is with a 10.5 wide tire and stock style suspension. Steven

MBHD Yes, but it's still not a rail car, so there's going to be some aditional difficulty there. Not insurmountable, just a bit more of an accomplishment when it's achieved.

Hi Harry,
his next race is August 8th.
Not sure if he has done anything else to his car.
I believe he will turn the boost up more,he says driving his race car is just like learning to drive a car all over again.
Very intimidating/scary ;-)
He has a new Y2K Turbonetics BB turbo he will eventually use, but for now he is going to play around/tunning with the 94 MM non BB turbo.
Other than that,I think he is just waiting for the next race.

Update,Douglas 1st run today 8.8 2nd run 8.6.
Numbers Taken from a local forum in Brazil.
The record holding Black Opala wagon ( which is 8.4 seconds),seemed to be on an 8.0 pass,but blew up the rear end. BTW he was running a lot of boost,but now also running Nitromethane. This info taken from a friend in Brazil.

Update, the class record was broken w/Black Opala wagon,record is 7.8 seconds now. No nitromethane was used,(3rd or 4th hand info) ,but he was running as much as 45 psi!!! Douglas running 25 psi in 2nd gear & only 14 psi in 1st. Douglas, still can only launch on 10 psi of boost pressure. Trans brake problems. Ran a 1.31 60 ft. This time out ,,no nitrous to spool up turbo. Switching to smaller BB Turbonetics turbo next time out. This pass 9.?? ran lean Still not dialed in yet,but it's pretty damm fast so far. http://www.youtube.com/watch?v=jBMHJ-O4l...player_embeddedMBHD

Thats making a little progress! Douglas running 25 psi in 2nd gear & only 14 psi in 1st.
Douglas, still can only launch on 10 psi of boost pressure.
Trans brake problems.
Ran a 1.31 60 ft.
This time out ,,no nitrous to spool up turbo.
Switching to smaller BB Turbonetics turbo next time out. This pass 9.?? ran lean Soon as he gets issues worked out I think it should go 7.9-8.0 pretty easy This time out ,,no nitrous to spool up turbo. BTW- Why no nitrous to spool the turbo? Steven

[quote=MIGHTY6] [quote] Thats making a little progress! Agreed.Soon as he gets issues worked out I think it should go 7.9-8.0 pretty easy Yes,transbrake,acting wierd also, w/trans brake, he could only launch @ 7 psi,w/out tranbrake he could get 10 PSI.BTW- Why no nitrous to spool the turbo? He decided just to spool it up w/no nitrous,it took several seconds in doing so though.Going from memory,,The specs on his turbo were 99 MM inducer,104 MM exducer,,w/a 1.45 A/R T6 turbine housing,,,,that's too big,and part of the reason he could only get up to 14 psi in first gear.S [b]The Turbonetics Y2K turbo has a .96 turbine housing,,,that should help out a lot along w/it being a BB turbo.
His plans (as stated earlier) on running a 1.1 60 ft time & of course setting the record & run 7's. GO DOUGLAS!!!MBHD

That car really gets the power to ground quick. It just squats on the rears and goes. No chassis flex(or minimal) and no front end lift.

Those of us who have trouble keeping our street cars on the road are fortunate to have guys like Douglas carrying our Inline Banner into battle! Thanks to everyone who is pushing an inline to the extreme. Old Red Chevy pickups at Bonnivelle , little blue pickups that saw off V8 Mustangs and lots more. It gives us all hope and bragging rights at the local watering hole! Tom

Douglas running 25 psi in 2nd gear & only 14 psi in 1st. is this a typo "nitromethane" or "nitrous" VP Raceing Fuels M5 has a little nitro in it? Any idea how much hp Doug car make with 25 psi boost?

The cars run on methanol ,,,ALKY
The same source I got my info from,,told me the Black wagon was using nitromethane,,,but later I found out this was bogus info,,sorry bout that.
Douglas has not dynoed his car w/25 psi,,,, but when he raced the record seting Black wagon,,,Douglas was 10-15 KM lower trap speed.IIRC?
I was told that the Black wagon dynoed at 1300 HP,,,,but he is running 45 psi!!! Yow!!
Also,,,the Black wagon boost launches @ 30 PSI also,,where as Douglas launched @ 7 PSI,but still got a 1.31 60 ft.
Douglas, needs to fab up some parts for the Turbonetics Y2K turbo before he installs it.

Thanks guys!! We are making some upgrades on my car to make teh car launch harder, and we´ll make some dyno session to get more power from the engine. I´m really happy with the goals... we are the third 6cyl car in Brazil to run on the 8s, and we did it in the second race of the car!!! That´s great!!!! So.... here is some pictures of the black wagon engine. This guy is racing that car since 2003. Pretty simple setup, but this car have a LOT os power!!! The turbo is a Bullseye S480 (80mm), 1.22 A/R. Steven... Nice work on the Mighty6!!! Hope to hear good news about the engine pretty soon!!

Is it me or does that turbo look big for a 80mm. Maybe I am used to seeing my dinky 78mm Any body notice there are no front brake rotors or radiator. What does that car weight because looks very simple and well thought out.

Last I talked w/Douglas,he had installed the Y2K turbo on & tried a few boost launches & then the turbo let go.
It had gone to 20 PSi while on the transbrake as compared to 7 psi before w/other turbo.
Wiped out the BB turbo.
I contacted Turbonetics to see if they could help him out w/the repair or replacement of his turbo,(only had 30 day warranty) But I had no response from them.
I tried. MBHD
