Well atleast we're both on the same page now :TU: . This turbo is a good starting point for us due to our limited power goals with this block. The cfm and velocity from our heavily ported stage 3's should help offset the ''lag'' from our heavy wheels and lack of ball bearings. The Nice thing about this ''diesel'' turbo is the fact that it's popularity has gained it a niche in the racing circle. The 85 mm wheel is also upgradeable to an 88mm wheel which actually will outflow PT's 88. Kudo's to you for undertaking that EFI project. My 1st forced induction car was an EFI turbo setup and I soon got sick of tracking down gremlins, unhappy sensors and malicious computers. Blowthru stuff is too easy nowadays for us dinosaurs. It's also much cheaper to run than EFI. There's several blowthru cars already knocking on the 6 second door. Blowthru cars have also become very competitive in drag radial classes where low 8's high 7's are the norm. It's just too bad the aftermarket hasn't yet caught up to the Buicks. You can order every hotside part for fords and chevs now to build a 400hp to a 2000hp turbo setup. Anyways keep an eye on us Jason
I think it's THE most helpful turbo database on the net for sure :TU: . PM away, I'll answer if I can
Bored so I thought I'd post more pics Aeromotive 6 Port Regulator Here's a cool gadget I've been using for a year on my car Innovative's LM1 Wideband with RPM converter Right now I use it to datalog AFR, RPM and Boost . I still have 2 channels open on it so I was thinking prolly air intake temp and water temp. I'd post pics of the CSU bonnet but it hasn't been polished yet so it looks like it belongs on a ford right now ou: Most of the engine parts are on the way. We still need to buy a fuel pump and bunch of hotside parts.
Confirmed, GRP billet alluminum rods with je custom dished pistons are on there way another set of cometic gaskets a custom solid turbo grind from cammotion it will all be here in a month or so maybe then we can post some pics :beer
I would have to agree totally. I have all the Buick sites marked and watch there for useful info also. But nothing I have found remotely compares, cept'n maybe speed talk. I had a one hit odd ball question there, and got an answer really quick. Also, far as I know, fastest hot blo-thru I have found is Bill L's camaro. He's 7.20's on 10.5W's(OSCA rules). I'm a Buick fan, but I'm sorry, I ain't seen anything that compares to that. Not yet anywayssssssssss. There is one coming. And it damn sure ain't mine. Mine will look like a pooch in comparison for sure !!!
The LM1 is a nice piece for the price and will aid in getting the car dialed in for sure. The CSU hat is also a nice peice. CSU and the EV have the best hats out there IMO. You can most defenatly spend a bunch of time modding the carb yourself getting it work via Blowthrough. (I spent about 80 to 100 hours on my first carb). Or you could call Quick Fuel or order a CSU carb that's setup. I went with Quick Fuel. Their Carb is like the Holley HP's wiht the adjusable bleads in the Metering blocks, and the PRVC's.. Very Very tunable. It came very close from as well. I swapped 2 bleads, and 3 sets of jets and it was dialed in. Buying a carb from a place like that will save you TONS of time and headache... Looks like a great project good luck with it. --Rich
Hi Guys, You all might want to take a look at a back-to-back comparison of the CSU & Extreme Velocity carb hats.....there's a good HP difference there! Just looking at the outside of the two different hats one should be able to see a definate approach entry angle difference.:Smarty: The EV hat also has a "flow-director" plate from the inlet all the way to the carb venturis. Here's the comparison details... http://www.superiorairflow.com/new_page_4.htm Here's my buddy's '77 Ford Pinto with a factory iron-head 147ci 2.3L we built of the winter....after you read the above link you will (more-than-likely:TU: ) figure out which hat we went with.:TU: Here's a link to his car at Gateway International... http://www.fastrides.net/board/viewtopic.php?t=17595 Anyway....best ET to date out of this little black Pinto is 10.54 with best MPH at 129.87. We had several problem dialing it in....blowing head gasket after head gasket....with only 19psi boost. Come to find-out Joe....being (almost obsessive at times) weight conscience (car's almost 3000lbs with Joe (he's big guy) )....was only putting about 3 gallons in the cell before a run. Then to make matters worse, while I was not around he and another buddy had used a l-o-n-g bulkhead fitting (long-side INou: ) in the cell when putting the car together.ou: Well we got those issues straightened out and then started blowing the hat off of the carb and breaking mounting flange ears on the base plate.:af: Come to find out on that one the distributor was slightly out of phase and sparking to the next terminal instaed of the one it was supposed to fire. Can you say EXCESSIVE spark advance??? Funny thing is it was not apparent till it was building boost...no cranking issues, nothing till you were on it hard. With a little more boost this is a 9 sec car easily! :Brow: Sorry for my rambling on.....
Hey Guy's, I'm personally using the EV hat. There are guys making big power with both of these hats. Both sides claim advantages over each other.... I personally feel you can't go wrong with either, but I do lean towards the EV which is why I went that route :Brow:
Thanx for posting that but you have to admit, since it was on EV's website it might be a little biased ou: I went with CSU because of their lower price and their EXCELLENT customer service. Kevin will give out his phone number and answer as many questions as u throw his way. I wish others companies would follow CSU's service. I've seen numerous dyno comparison's on TM.com with both bonnet's and with or without spacers. The numbers are always much closer than EV's claim. It's funny how the big carb companies are now also trying to cash in on blowthru stuff. BG has a full lineup of bt carbs now too. I modded my blowthru 650 with relative ease thanx to this great website http://www.hangar18fabrication.com/blowthru.html My carb runs absolutely great from vacuum thru 12psi boost. I just set the jetting up on the dyno to 11.9 across the board. ANyways blowthru is the way to go :TU:
I agree....being on EV's website is more than likely biased towards their product.:TU: BUT.....looking at the hat's and thinking of an intake port what do you see from just a glance? What I see is the CSU hat has a hard 90 turn into the carb on both the long and short sides (major turbulance if left unchecked). The EV hat is a nice smooth radiused turn just like an intake port bowl should be. Think of how a port will flow with that same sharp 90 at the top and bottom of the turn like that in the intake bowl?o No: Definately does not enhance flow I can assure you of that!:grin: I will say that I have not seen a CSU hat in person but from the pic's I have seen of them, there is no flow-director to even help turn the air either?o No: I just "see" lots of turbulance with that hat compared to the EV. These are just my thoughts concerning these two different hats. Next time my buddy has his hat off I will try and get a pic of it to post here to help show what I'm talking about.:TU: Anyway...BEST of luck with your project, hope to hear more of your progress in the near future!:TU:
