Sneak Peak: Superman09's 98-02 Turbo Kit

[kammi10]

Because I am building a turbo setup for my 3rd gen. That intercooler "appears" to be about a 31 x 12 x 4 total length.

if it is the same as me the main part of it is 28 inches wide and then you have the peices where it comes off for your couplers. with an inch and a half on each side it would come out to be 31x12x4 like what u thought.

The thing that I notice most about the kit, is that your hot side is based off of what people "think" is the best size. Is there any real math or calculations to your hotside? What makes a 2.5" crossover effiecient UP TO 1000 RWHP? I think if you plan on mass producing this kit, you need to do some calculating.

I'm not trying to bash your setup but, if you are going to sell this it needs to be built as the most effiecient design. I personally wouldn't waste $3,000 for a kit based on what you read on a forum. You didn't say well, I did these calculations and based off of this data, we determined that 2.5" piping is the most effiecient way to reach our power goals of 550-600WHP.

Every kit produced out there is 2.5". I have done PLENTY of homework and have been into the turbo LS1 game for 5 years now..... 2.5" IS the correct size for the crossover and 3" IS the correct size for the downpipe for this kit and people wanting to boost their LS1 from stock form and up into forged applications! If you want to build a kit with a 3" crossover then be my guess but the only thing that extra size is going to do is kill your spool time! I know what's happening here sir

if you ever need a test vehicle for an LT1-maggie kit you know where to find me

And if hes not available im willing

Can a mod please clean this up? This is an informative build thread and I don't need it filled with an argument of strict criticism. Thanks!

If this is an informative thread then why not acknowledge his concerns with facts? He does bring good points to this build. Also isn't that the point of a thread that people can post comments and concerns?

I know my opinion doesn't matter because i'm new to this site but in not new to the game...

cleaned up and moved back into power adders forum

Everything has been acknowledged. This kit will utilize the following based upon personal experience, and other PROVEN set-ups.

Being built for: 98-02 LS1 street/strip car from a stock engine 500 rwhp build to a forged 400+ CI build looking for 800 rwhp. After that a larger downpipe would want to be looked into

Features:

Hot side= 2.5" Cross over with T4 turbo flange. The 2.5" Cross over is proven to provide great spool time on even a stock motor and can be capable of far more than the turbo is capable. 3" V-banded downpipe. A 4" Downpipe will be looked into for a future option for those running a larger frame T4 and a turbo style K-member for clearnace. 38mm Wastegate flanges off cross over and to recirculate back into downpipe

Cold side= 4" Core intercooler with custom bracket requiring no cutting or modifying of the car. 3" Cold side piping from turbo to IC and IC to throttle body. 50mm BOV v-band flange between intercooler and throttle body.

Will include all couplers and t-bolt clamps minimizing couplers as much as possible (entire cold side is just 3 pieces). Will include a bracket to relocate the alternator as well.

Kit is being built around a Master Power T76 Q-trim turbo.

Kit is going in for a sample make here shortly

also if you guys are not interested in this kit please bow out now.

This is what is beings made. If there is enough interest(from people who are actually going to buy a kit) than a 2" version will be made....

Update for the rear mount guys..... I hope it is relevant to this killer thread. I finished the new 2" cold side and it made a BIG difference....power, spool and even with drivability on tip in. Just to recap what i've done the past month, i fabbed an entirely new hot and cold side twin rear mount system and relocated the turbo's up and in for better ground clearence/straighter shot. I had a twin STS system before the changes and it worked well for what it was (683rwhp at 14 pounds). I changed the hot side from dual 2.5" all the way to the turbo's to dual 2.25" and then stepped down to 2" just before the turbo's. I also installed larger housings at the same time, went to t3 .82's from .63's. The hot side change made for quicker spool with less backpressure (with larger exh housings). Then I changed the cold side from dual 1.75" to dual 2" and also shortened the cold side piping at least four feet per side. With the new system, it transformed the car!! I played a bit on the way to work this morning and it is stupid fast now (relative term)! It comes in quicker and much harder versus the STS system. I will try to take some pics tonight to show my new system. This weekend I'll do a backpressure test and update with results. p.s.... i moved my hp goal up to 900+rwhp!! I think i'm there now under higher boost (22 - 24 pounds or so). Boost is so addictive...... Thanks for the help phil and casey


Cliff notes
Smaller hotside tubing
Large A/R on the exhuast side of turbo
Larger cold side piping

Anyone reading this would think, hmm smaller hotside equals more backpressure right? Larger A/R turbos equal more lag right?

Read the whole thread, it has good information
Its also on ls1tech.

2" piping is lighter, cheaper, will spool faster and work with 90% of everyone on Mifbody's turbo build with supporting information and data to prove so. Sounds like an efficient budget kit that works and has good data. Somewhere north of 1200+HP is when you would switch to a 2.5" kit

Cleaned up the thread again. Keep it on topic, there's no reason to argue here about it. If you want to argue about turbo kits, start a new thread in the FI forum. Don't clutter this thread with that nonsense anymore.

Thank you! If you want to post your ideas or your findings, make a thread about it.... this isn't the place for it! Also if you want to discuss rear mount twins, please do the same as this is for my f-body single front mount kit!

arent you doing a turbo setup?

[Superman09]

deciding on final materials to be used. thinking 304 or 321 for the hotside and debating between stainless or aluminum on the cold
