A big dog for sure!


Juan, How about a few details please and a pic of that shiny stuff under the tail?

I don't want to hijack the thread

That was at 28 psi of boost but in reality I run 32 when I have the chance, for SURE that in the next mile event I will have the chance again we have done so much R&D that I don't even remember many details I know she will pull 7800 rpm 16 psi of boost, we have to remember that my turbo is HUGE and is a Dinosaur by todays standards however I hope to install a Precision 67.81 with a billet wheel very soon.

this is the latest set up all done by Bello

I have to ask, what was the source of the headers, muffler, & intercooler if I may?

I figure to pull that kind of rpm and boost it has to be a huge turbo and probably dose not reach full boost by 3000rpm.

I don't know the intercooler is one of those for big supra horsepower that he modify, the rest is custom.

don't forget, 3LDZ Brick as well... - you can definitely see the advantage of the K27 series in boost vs. RPM... (sigh)

Then again, the ONLY mod to this car is exhaust (headers & muffler) - and that made a significant difference. (and more so in the weight department)

Juan - are you using the stock 3.2L fuel rails? And, you are single plug, right?

Looking good Tony!

Yep we are still single plug, rails are factory with bigger fuel lines, that muffler was made by Jose Estevez from Turbo Werks, I will see if I can get photos of one that Bello did no long ago

EmptyGarage,

What a great data set with boost data on an interesting build.

Looks like a .8 bar and a 1.15 bar (1.8 & 2.12 bar) boost setting made about 335 v 375hp.

That is 20% more boost yielding 11% more HP. Also, the .8 bar peak HP was at a higher rpm.

I am not an expert but something may have become a limitation. The 7006 has a great hot side and a K29 compressor should not fall off especially with EFI but something seems to be costing efficiency with more boost. (edited)

At least that is my guess.

Again, I am not an expert but I would think Groupe B cams would make there power at a little higher rpm possibly indicating some limitation.

Sorry, I can not help myself. Great build and data.

This is RWHP so over 400 flywheel with 100 leaded @ near14 psi boost. Electromotive XD12ECU @ 25 BTDC. Another setting will program in more fuel and another 4 degrees to 29 BTDC when using 110 octane fuel. Enrichment is both Andial and Miller Woods set ups with larger injecters and injecter blocks to the hone matched intake and heads. We did not do another pull that way as fuel and time did not permit however the shop said it woud have some more HP but do not use the 4 more degrees but for short runs like 30 secs or so.. Motor inside is 7.5 compression 3.4 w B&B headers, Tial waste gate, heads ported and polished to 38MM larger intake exhaust valves, not sure of the cam grind, Garrett GT35R and lower end just redone with the good stuff. I suppose I could use more boost but this shop builds road race motors to last so they recommend pretty conservative boost levels.

Your right on . I was interested in that car also. I spoke with Chris@turbokraft who had the car for getting it set up after years of non use. He thought a Garrett turbo along with EVO cams and more fuel up top and better intercooler would compliment what he thought was a great build otherwise. After finding out how much more to spend to get it finished, I decided to keep the one which I just put up the dyno sheet for, as it was a fresh build earler 930 (1979). Also the leak down numbers varied on that other one.

Tony,

I love playing amateur tuner but I have a lot to learn.

Your post that peaks HP at under 5500. Dose that look like a stock cam? Also, what muffler dose it have?

I had 91 C2T with Andial/S2 intercooler, SC cams, ports, 7200, B&B's, my own programmable control pressure based fueler based on Andial Plumping that I dialed in on a load dyno for ideal AFR's.

I came up against the same HP level. On a whim I cut open the B&B muffler to find the largest internal passage was 2.5"d.

With a Borla straight through right side exit muffler I added 35hp at .9 bar.

???

The muffler has the exit on passengers side. The records just say cam sent out for reprofiling, maybe 964 or SC sort of grind, however stock cams seem to get hp from 3500 to 5500 . these are from 4500 to 6500. but I do not think to evo or groupe B specs as I have these cams in other cars and they do respond differently. Thanks for your suggestions. I do feel it puts out good hp with over 400 FWHP @ 13.8 psi. I'm sure I could get another 30 or so with more boost and the timing and enrichment dialed in. However as I previously mentiond the shop that did the dyno tune for me sets them up to run the road course. So for short runs I could get more out of it but its fast enough if that means it will last longer this way. Besides the car is bone stock looking otherwise with just turned 38K miles by the first owner. He got the more HP bug @ around 36k miles but did it wrong so he cooked the motor with just more boost and add ons. A good shop did this hot street build for him ( it took awhile so he bought a new one instead of waiting ) so it works well ( sleeper ) for the way it looks.

This is 2 1/2 years ago at TPC ( Mike Levitas - former Daytona Rolex winner & Charlie Murphy engine builder). It was 98* in the garage - see the ice bag on the I/C.

Engine is 3.3 with Carrera intake/TB, 951 injectors, SC cams, ported heads, Koklen i/c customized to fit the intake, GHL headers, K27, ARP bolts, EBS tuned the heads coated the piston side skirts. Prolly couple of other things we did I can't remember. These were 80 and 90% runs. We hit 426 rwhp at .8 bar.

oops, forget the Motec

Dyno run at TPC

Tony spoke as well as I could about this car. The grade B cams are the major issue here.

One side note was that the owner said that this was a dialed back tune and the car makes 400+ hp when programed so.
